  1. The manual's wrong. I seem to remember you have to go to a set-up menu somewhere to enter the location, which can either be a city or a lat/long. The mount remembers the last location you entered, so you only need to change it if you move location.
  2. I agree it's worth persevering with the StarSense. I can't imagine going back to doing manual alignments. I know it's not that difficult to do a manual alignment, but you have to do it every time you switch on the scope. I love watching the StarSense do its stuff. It even works in twilight, when I'd struggle to do a manual alignment. After the latest beta, planets as well as deep space objects are spot on.
  3. The instructions in the manual on how to do "Calibrate Center" are just plain wrong (or at best, out of date). It caused me a lot of frustration when I first got my StarSense. proflight2000 posted some instructions that worked for me:
  4. StarSense is working very well now, unless you need ASPA (which still hasn't been fixed). The latest beta got the planetary positions spot on. I believe the CG-5 needs a modified splitter, which Celestron will send you. I'm very pleased with the performance of StarSense on my NexStar 4SE. It aligns very quickly and accurately, even at twilight.
  5. I have a 4 SE and a StarSense. The combination works very well. I'd have to take time and care in aligning to do as good a job as the StarSense. The StarSense is much quicker and more convenient. The StarSense is particularly impressive at aligning at twilight and on part-cloudy nights. The goto accuracy is spot on with stars. At the moment, it's less accurate with planets (Mars is just out of the FOV of a 32mm EP), but judging from posts by Celestron on Team Celestron, that's due to a known bug in the way the StarSense hand controller software calculates planetary orbits rather than any intrinsic limitation in the StarSense. It's slightly frustrating that you can't mount the finder scope at the same time as the StarSense on an SE telescope (though I might try some double-sided adhesive tape).
  6. Is there a list of changes in version 1.10? I've ordered a USB to serial adapter so that I can perform the update.
  7. I've been wondering how to attach my red dot finder scope to either the OTA or the StarSense camera. Do you find that double sided tape attaches the finder scope securely enough? Would you be able to detach the finder scope again without damaging the paint on the OTA? What kind of double sided tape did you use? Where did you attach the finder scope to the OTA? How did you get the finder scope aligned? Did you centre the telescope on a star, then point the finder scope at the star, then carefully attach it to the OTA? Sorry for all the questions, but I'm very interested as I'm also frustrated by the inability to use the finder scope at the same time as the StarSense.
  8. Thank you very much. That's a very helpful list of instructions. It was step 7 that threw me (it's missing from the manual). Once Chris Rowland told me I needed to press Align, I was able to "calibrate center". Like yours, my camera was quite a way off and I really missed my finderscope.
  9. I have a Celestron 4SE. My version numbers are: StarSense HC Ver: 01.07.13311 Bld: Nov 7 2013 StarSense Camera Ver: 01.01.13285 Motor Control Mdl: SE 4/5 Azm: Ver: 5.20 Alt: Ver: 5.20 I had no idea that Polaris would be a poor choice of alignment star. I tried a number of other stars first, but none of them were in the field of view of a 32mm eyepiece. I eventually calibrated using Polaris because I knew where to find it and it's the only bright star in that part of the sky, so I could find it more easily without a finderscope. I'll repeat the alignment with another star. The alignment does seem pretty good already. The only problem I've noticed so far is that Mars is consistently slightly out of the field of view of a 32mm EP. However, posts on teamcelestron.com suggest that the problem is with the algorithm used to predict planetary orbits, not with the alignment. That's all very well, but if you don't know to press Align after slewing to a star (that step is missing from the manual), then there are no instructions to follow on the HC. My impressions of the StarSense so far: Likes: - It's worked first time every time for me so far. Last night, it calibrated during twilight when only a few stars and planets were visible to the naked eye. I find it much less fiddly than doing a SkyAlign and it gets me observing much quicker. It's particularly useful on a part-cloudy night. Dislikes: - I don't like the fact the StarSense camera replaces the finderscope. The lack of a finderscope made it very difficult to carry out the initial "calibrate center", and I don't like being totally dependent on the Goto. - The mistake in the manual is pretty poor for an accessory that's marketed to beginners. How hard would it be to update the PDF manual on the website? - I find the user interface clunky and confusing (though no worse than the user interface for the original NexStar handset). Most tasks require a confusing mix of Align, Enter and Back.
  10. But if you don't know you should press ALIGN, there are no prompts to follow on the HC.
  11. I was able to centre on Polaris. It wasn't in the field of view of my 32mm EP, but it was the only bright star in that piece of sky so I was able to find it and centre it.
  12. I'm both impressed and very frustrated with my new StarSense. The good news is that it aligned every time the other night, even though it was part cloudy. The bad news is that I can't get the StarSense aligned with the telescope (a NexStar 4SE). The StarSense "Calibrate Center" doesn't seem to behave as described in the manual. The manual says that after pressing ENTER to slew to a star, pressing ENTER a second time should switch to fine centering mode, but it seems to slew back to the starting position again. A post on page 1 of this thread by hrgreen stated that "the Calibrate Center operation is not correctly detailed in the manual". Could anyone explain to me how the "Calibrate Center" operation actually works? A secondary problem is that the alignment between the StarSense and the telescope seems to be quite a long way off, even with a 32 mm eyepiece. I think the StarSense camera calibrates correctly because when I slew to a star, the telescope does slew to the right part of the sky. The problem is that the star is nowhere in sight in the eyepiece. It's very frustrating that you can't attach the finderscope at the same time as the StarSense camera. When I tried slewing to the moon, although the telescope was pointing in roughly the right direction, I found I had to move the telescope some way before the moon came into view. Could I do a rough align to the moon, then the final alignment to a star? Or is "Calibrate Center" a once-only operation? I find both the user interface and the manual rather hopeless! Any advice gratefully received.
