  1. Hi OJ87. I had problems with the Mesu meridian flip at the beginning. Mostly due to me not having a clear picture in my mind about how the Sitech controller on the eMesu 200 works. From a post I put on the Mesu-Mount group chat: "The SiTech controller has two important settings - the meridian limit and the track past meridian overlap.If you are tracking an object as it crosses the meridian, the mount will continue until it reaches the sum of the meridian limit and the track past meridian overlap. It will then stop.If your session management software tries to execute a meridian
  2. Another rare clear night. Quick! Image something! The Flaming Star area in Auriga in widefiled. IC405 with IC 417 and NGC1931. Plus M36 and M38. 100 x 240 sec OSC subs with Optolong L-eNhance filter. QHY168C camera, Canon 200mm F2.8 lens. First pass at processing with Pixinsight.
  3. Interesting. With a couple of clear nights every couple of months I would not risk nightly updates! But when a full release has bedded in... I do like the interface!
  4. NINA will not (yet) close up the observatory at the end of session or if it rains. Voyager will. NINA has no scripting language that I can find. The Voyager one is very sophisticated (at least so far). It also has a web browser interface so you can operate obsy from tablet or phone.
  5. I too have found NINA to be both flexible and stable. The interface is excellent and it is pretty easy to do the things you need, manually or in automatic sequences. For attended sessions it is fine, and my personal preference. however, it is less suitable for unattended/remote operation. For that I am persevering with Voyager. Much more complicated, and harder to just make things happen first time. But immensely powerful and capable of full remote operation, with error recovery, interaction with ancillary equipment (observatory etc) etc. So far it has worked well for me, and I am sneakin
  6. Just finished reading A History of the Universe in 21 Stars (and 3 imposters) by Giles Sparrow. A Christmas gift from my partner. As well as a reasonably comprehensive overview of how our universe got to where it is from its beginnings, it is also a very good trawl through the history of astronomy. As the title suggests, it looks at 21 individual stars, with a chapter for each. Either as representatives of an important stellar class that tells us something about the universe, or as the specific star whose study pushed our understanding forward. The three imposters are things that looked l
  7. I use NINA quite a lot, but don't suffer that problem. In NINA you have told it which is the main camera, and in PHD2 you have told it which is the guide camera. I just then walk down the list in the Equipment tab, turning on one item at a time. I then get the message as each connects to NINA. Works every time. Sometimes, NINA throws a wobbler if the main camera is not connected, but it is fairly obvious what has happened, and it is just a question (for me at least) of unplugging and replugging the main camera. If you have set up your equipment list correctly, it should just work.
  8. Very nice. I like the folds and swirls in the nebula. The bi-colour works well on this target.
  9. Thanks. I was genuinely surprised given how washed out the sky was. I think this Optolong L-Enhance filter is a keeper.
  10. We have had little in the way of clear skies since Christmas, so when the chance arises you take it! Inevitably, the skies cleared when the moon was up and approaching full. I definitely did not need a torch to find my way to the obsy. But clear skies, so go for it! Pick a target by turning my back on the moon - the Heart and Soul Nebulae. Across 2 nights I got 90 x 240 sec OSC subs with my QHY168C with the Optolong L-Enhance filter on a Canon 200mm lens. And here is the first processing pass. Not bad as the moon was so bright I could scarcely make out the Cassiopeia W.
  11. Correct. I found out from Mesu that SiTech.exe must be set to ignore or strange things happen.
  12. Very nice indeed! That's what I hope mine will look like with some more data. When I get some .
  13. Yes it was calibrated, but I may have screwed colour balance by stretching too far and not doing well enough on gradient and background neutralisation. I don't think it is worth going overboard in an attempt to to produce a better image. I'll wait until I have more data. Judging from the HFR measurement and star count for the subs, there was some wispy cloud or high level haze around. Just pleased to get anything, and how hearing about storm Christoph about to spend the rest of the week dumping hugea mounts of rain on us it may be some time before the next session!
  14. I have recently added a side-by-side bar to my rig with a Canon 200mm F2.8, QHY168C colour camera and Optolong L-enhance filter. I haven't been able to do any imaging at all since Xmas because of the continuous rain and the perpetual clouds. Last night there was a small gap predicted, so I went out to finish setting up, check focus, balance, guiding etc. Having done that, there were still some gaps in the cloud towards the zenith, so having been focusing on Capella, I switched to IC405 and started some data capture. I got 46 mins in 2 min subs before the cloud rolled over, so here is a cr
  15. Ahh! That could be a problem. At least it did not cost much
