  1. Brilliant! That’s what I wanted to know.
  2. I did wonder about that in my naive way.
  3. Like this it seems https://medium.com/@EvgeniIvanov/how-to-verify-checksum-on-mac-988f166b0c4f
  4. Thank you both. I have no idea how I would go about using them so they’re rather wasted on the likes of me.
  5. Incidentally @gilesco on the KStars download page you linked what are the MD5 and SHA256 files? I didn’t download them before and yet my set up seems to work without them so what are they?
  6. Thanks. That’s how I originally downloaded the KStars I’m now using. It came with EKOS and INDI included. I wonder now whether I can just download the newer version on top as it were of the version I’m using, or whether to delete my current version before downloading the new one? I’m worried about losing all my device settings and the files used for the plate solving.
  7. Just that really .... how do I update KStars/EKOS/INDI? I run KStars/EKOS/INDI on my Mac with devices connected directly to it. I don’t use an RPi or similar. There doesn’t seem to be an update button in KStars, and anyway INDI might be updated differently. I’ve tried googling and searching the INDI forum and found nothing. Well except people saying they’ve updated drivers but not how to do it. I assume this is such an elementary question that no one thinks it needs explaining. Thanks for any help.
  8. Nice rich star field. The North America nebula stands out well, and the nebulosity around Sadr. It’s amazing what’s in Cygnus isn’t it. I reckon one clear night a week in Cornwall is doing quite well.
  9. Yes @ShrewView. This time I used the automatically selected points, size 48. I think it generated about 30 if I recall correctly. Anyway, the weird box has gone! This is the new image. It's the best 25% of 5 x 1000 frame AVI files. So it's using 12.5 times more data than my first attempt. I don't think it is very much better in that it hasn't brought out more features. Maybe it is slightly less noisy. An interesting exercise anyway. Thank for all the help.
  10. Thanks. I did wonder about that. On this occasion I did manual selection of the align boxes whereas before I used auto select. I’ll give it another go.
  11. OK I had a go at using PIPP to combine 5 AVI files all taken over about 15 minutes - 5000 frames in all. All seemed to go swimmingly through autostakkert and Registax until I started sharpening when I noticed the strange rectangular artefact in the image below. I've slightly exaggerated the sharpening it to make it more obvious. It doesn't appear to be in the original videos, but I can just see it in the TIFF output file from Autostakkert. Any ideas?
  12. Is there any correlation between clear skies and the period around new moon? It’s probably my imagination but I sometimes have the impression that it is more likely to be cloudy when the Moon is out of the way and it’s best for imaging.
  13. Didn’t we have many a clear night during full lockdown earlier this year? The problem for me was that I do almost all my imaging in Cornwall, but couldn’t get there because the travel restrictions. Being ‘socially isolated’ from my scope was very difficult especially when I saw night after night of clear sky go by.
