94005 StarSense Automatic Alignment Telescope Accessory, Black

I'm not sure Celestron aren't milking it a little with the separate autoguider, Be nice and would seem to make sense to combine them but I guess that's business and there may be technical reasons, perhaps. But it's a great bit of kit, I still take time to polar align as well as I reasonably can after all it's not going to hurt - and anything to get the best results. It's quick to get going and within a couple of minutes it's oriented itself and you can then further add precision by adding other stars, systematically using a more powerful lens and then precision tuning it. It's not cheap clearly but really does mean you can get viewing quicker which is even better if it's not an entirely clear night, or you only have a short time. Reassuring too as it's scanning numerous stars across the night sky. After a quick alignment I've certainly had stable 45s-1min 15s exposures.

Excellent item. I use this to align my avx mount. Once calibrated to your scope setup it works great. I run it from the cpwi software an not the handset. I think I set the axis limits to 20 degrees so it won't search for stars below my fence line. The calibration to your scope is very important but is not difficult to do, an you don't have to calibrate each time you use it. Once you click the star sence auto align ,it only takes a few minutes to align it self. You can also run a polar align routine if you want to get your mount spot on, but read up an how to do it in the instructions first.

I believe when this works it’s great, however mine didn’t work and Celestron were not very helpful. I don’t think it worked from day one but it was very hard to be sure. I eventually managed to get it to connect to my computer which brought up an error fault and when I contacted Celestron they told me it was out of warranty but they could look at it and see if it was possible to repair. It wasn’t and now it sits reminding me to beware of making expensive purchases!

First time out, seems to works well, no more fiddling about for ages finding/centering alignment stars. Magic to watch it do it all itself, much faster than you can! (Everything (location,time, mount mechanics) has to be set correctly of course.) Its a bit pricey, but there is a lot to it, and the quality is good. Note: there is no new version of nexremote (to do the pc mimic of the new handcontrol), which is a shame - i found that really useful with the original nexstar handset. However, to make set up easier without nexremote, Ive found I can set the location and time data from a laptop via the starsense handset serial port, communicating with the same command protocol as the old nexstar handset. Once aligned, Goto's etc should therefore work with stellarium etc, communicating through the serial port, but i havent tried that yet.

This accessory works very well now and I am able to auto align and GOTO stars and planets with ease. At the time of writing this review, it does not yet work with all Celestron GOTO mounts such as the GT but they are working on it. Be prepared to spend time updating the camera and handset to the latest firmware online. The manual that comes with the unit does not explain how to do this. You will need to join 'Team Celestron' to download the latest update(s) and connect the handset and camera to the PC and the mount to install. Alignment is very accurate. Overall very pleased so far with this purchase, it saves a lot of time and effort aligning my C8 AVX telescope. ***** Update **** Planet pointing has now been fixed, planets and earths moon now appear near or even right in the centre of the eyepiece every time. Polar Alignment has also been fixed. You will need to download, install and update your mount and StarSense camera to the latest version from the Team Celestron website. Recommended.

Great piece of kit. Bit pricey but worth it makes star gazing a lot better...

Without doubt, this is the best accessory I have bought for a telescope. Initial set up took a little while but was straight forward. Now I have a fully automatic scope that works flawlessly. Select the auto-align option from the replacement handset and the scope moves to various parts of the sky and after a few minutes it is done. Now select from the thousands of objects and it will put the item in the centre of a 20mm eyepiece. It makes casual stargazing in town so simple, even I can do it.

This was a christmas present. But it never worked. When it arrived the box was ripped and damaged. Put it onto my celestron 8se and got error messages I tried for ages to get it working and waited months for a clear night to first use it. But lucky Amazon was very positive and helpful. Got a telerad now stay manual.

I apologize for the length of this review, but I thought the details might be helpful for folks interested in this awesome little gadget. My Celestron StarSense arrived last week, and I’ve had a couple of chances to try it out. I’ve used the device exactly twice, but I think my experience may provide some useful information to others who are thinking of purchasing this device. My focus is on astrophotography and my rig is 100% portable on a tripod, so alignment is a frequent chore. I held off buying the device because I had read that it had severe issues integrating with Celestron’s native polar alignment process, ASPA (All-Star Polar Alignment). Once those issues were corrected by Celestron and I read a positive review of the device in Sky and Telescope, I went ahead and bought it. So far, I’m very glad I did. After unboxing, I immediately updated the firmware on the StarSense camera and the included hand controller. Be sure to do this – as I mentioned, Celestron fixed some major problems with the software since the release of the device, and you’ll want to be sure to capture these. Be sure you have the appropriate cables and adapters ready for this. Once the firmware was updated, I attached the SS camera to my scope. I have a non-Celestron OTA, but a Celestron Advanced VX mount. This was one point of annoyance with Celestron. They provide two mounting methods – a super-solid one for Celestron OTAs, and a not-so solid one for everyone else. I was mounting to a dovetail plate, and it was annoying that I couldn’t use the more solid method just because Celestron had made the mounting holes too narrow. If they had just provided a couple of holes at the standard mounting sizes they could have given folks a lot more options. Left with the secondary mounting method, I was glad I had an extra mounting base available, because Celestron doesn’t provide one with the unit (they assume you’re replacing your finderscope with the SS camera). I sacrificed my mounted laser pointer in favor of the SS camera and continued. If you have a single finder\guider and no other mounting base available when the unit arrives, you’ll be waiting for Amazon to deliver before you can use the unit. After setting up outside and doing a rough polar alignment with a polar scope, I turned on the mount with the new HC and SS camera attached. The first thing the HC does is search for the SS camera, which it found with no problem. At startup, the HC gets a little “bossy” – there doesn’t seem to be a way to start up without going through the SSA (StarSense AutoAlign) process before doing anything else. I’m used to entering the Date\Time and location, but that didn’t seem to be an option at startup. You can press the Menu button to add those details, but I didn't know that at the time. I let the SSA do its thing, and it slewed to four different sections of the sky. I was in my side yard, where the house and trees block much of the horizon, and light pollution is fairly severe. I had also neglected to turn a bright flood light attached to my roof off, just to keep things interesting. I started quite early, and I could only see 5-10 stars visually. I noticed that the HC was reporting that it was finding dozens of stars in areas of the sky where I still couldn’t see any. After a couple of minutes, the SSA wrapped up and reported success. At this point, I was 90% certain that the device hadn’t actually done anything – it was just a little too quick and easy. I told the HC to find Albireo. There it was – off center, but within the FOV of my 20mm eyepiece. Not bad. I told it to find Antares in the south. There it was. Whoa. At this point, Celestron has you resolve the error between the SS camera and your telescope by performing a centering procedure. This is done in the HC’s software and doesn’t involve adjusting the camera physically, which was a relief – I think I’ve had enough “dance of the thumbscrews” for one lifetime. The HC has a process for this that involves centering the star in your eyepiece and then confirming that it is centered with the HC. This was simple enough, but the (printed) instruction manual actually has a mistake in it about the steps in the process. It's a good idea to just download the (corrected) online manual if you buy this device. After the centering procedure, the HC tells you that you will need to repeat the SSA process. At this point it was a little unclear whether it expected me to simply run the process again or actually reset my mount to the alignment marks and start over. Thankfully, the former seemed to work just fine. Now, I had done all of this before entering the date, time or my current location. It seemed wrong to move on to polar alignment without entering that data, but then again – does the HC need to know the time or location if it knows the positions of all of the stars, especially if you’re not targeting solar system objects? The HC certainly didn’t seem concerned about it – I had to go menu surfing to even find where to enter the date\time\location – I was never prompted for the information. I went ahead and entered the info and the HC told me to perform SSA again, which I did. The polar alignment process was simple. ASPA normally has two steps – the first where you center a star using the direction buttons on the HC, then the second when you’re asked to center the same star using the mount’s ALT and AZ alignment knobs. With SSA, the first step is done automatically and the user is left with the ALT and AZ adjustments. After the centering\calibration process and ASPA, any stars or objects I selected were perfectly centered in the reticle eyepiece. I spent some time selecting objects near the four points of the compass and just being amazed when they all came up dead center. I started guiding and did some test shots using the CCD – I had perfect pinpoint stars for 12 minute exposures. That night I took 14 12-minute exposures of the Pelican Nebula and had some of the sharpest, roundest stars I’ve ever imaged. Long story short - ASPA was very easy and very accurate. On the second night out, I was just doing a rough alignment so I could take pictures of the moon with my bigger scope. I simply took the device off my refractor and put it onto my SCT, put the OTA on the mount, hooked it up, turned it on and let it align. I started even earlier that night, with only a few stars visible to these middle-aged eyes. No re-centering or fine-tuning, no entry of date or location, no polar alignment. A couple of minutes later, the SSA was done and the GOTO put the moon in the FOV of my 20mm eyepiece on the first try – this is with a 10” SCT – the FOV was less than a moon-width. I also tried several stars and they were all close to center, despite a different OTA and not performing a new centering\calibration procedure. The bottom line: this device exceeded expectations on its first two nights out. I’d say if you have a portable setup this is a no-brainer purchase. Pros: Easy setup (other than the firmware update); easier telescope alignment; simplified ASPA; more accurate polar alignment (at least in my experience). Works in twilight, so you can start your alignment earlier. Works despite trees and\or buildings obstructing large parts of the sky. Fast. Cons: Mounting brackets aren’t all that they could be (see above). Finder mount base not included. New HC has small-print display by default – can be hard to read especially from a distance.

Compré el StarSense Autoalign para simplificar la alineación de un telescopio Nexstar 8SE y puedo confirmar que funciona de maravilla. Es fácil montarlo y la fijación es muy solida. Una vez montado es muy rápido y no hay necesidad de identificar o localizar estrellas: alinea automáticamente el telescopio. Lo pones en marcha y se puede observar en pocos minutos. Es bastante mas preciso que hacer la alineación manualmente. Lo uso con un Celestron SkySync GPS que busca la hora, fecha y y la longitude y latitud de forma automática (algo muy útil si observas en sitios distintos). Es caro pero merece la pena si quieres pasar menos tiempo montando el equipo y mas tiempo observando el cielo.

premessa 1: possiedo un nexstar 6se, quindi perfettamente compatibile con l'accessorio; premessa 2: trovo l'allineamento con il cercatore in dotazione, ai limiti dell'impossibile; dato tutto ciò e leggendo varie recensioni positive, mi son fidato ed ho fatto l'acquisto dello Starsense. Risultato; dopo 3 giorni di utilizzo è una delusione, almeno per me; da qualcuno è stato paragonato ai "vetri elettrici" di un'auto....io lo paragono ai "vetri elettrici che si chiudono solo a metà in un giorno di pioggia"..... (quindi inutile.....). Il dispositivo è parecchio impreciso nell'allineamento; diciamo che punta sì la stella, ma.. "+-", con un errore anche di 10 gradi; e chi punta le stelle sa che anche una differenza di 1 solo grado rende la ricerca e visione della citata stella, in un oculare, del tutto impossibile. Così equivale a cercar un ago in un pagliaio. Oltre a questo, in modalità "auto align", va a caccia di fonti luminose dappertutto; il risultato ? a meno che non viviate in un ranch americano a decine e decine di km da un lampione, lo Starsense si "attaccherà" alle luminarie della vs strada e da lì non si schioderà più. vi scrive "acquired 100 stars" e poi impazzisce. metto 2 stelle solo perchè, montato sul nexstar, fa "figo" quando il telescopio è in casa. --- AGGIORNAMENTO DOPO VARI ALTRI TENTATIVI --- quando ci vuole...ci vuole: mi devo ricredere. Dopo AVER LETTO parecchi forum e spiegazioni d'uso in internet, ho trovato la "quadra" ed ora il dispositivo funziona benissimo; la questione è proprio questa: essendo precisissimo nella ricerca, la sequenza delle operazioni da fare (....modalità "manual align"....) per allinearlo DEVE esser altrettanto precisa; è vero, SE tutto è perfetto, in 3 minuti avete allineato il vs telescopio. Ecco perchè ora mi sento di metter 5 stelle al prodotto :) mi raccomando...CERCATE in internet la sequenza ESATTA; il manuale (esistente peraltro SOLO in inglese..... ) non è abbastanza dettagliato in merito. e buona visione stellare a tutti ! :)

très bon accessoire pour tout télescope celestron et autres marques également .permet un alignement rapide et sans prise de tête .pour débutant surtout mais produit trop chère qui équivaut à s’acheter un deuxième télescope donc préférer plutôt un chercheur de bonne qualité et professionnel dans une gamme de prix abordable

Genial. un poco complicado de usar al principio, unas dos veces y practica, y alineas tu telescopio en 5 minutos.
