  1. Now that is nice! I'll download RC 0.19.1 immediately and see if I can find out how this works. Edit: I can't find an .exe or .msi. Just ... Stellarium-0.19.0.16932-x86_64.AppImage Stellarium-0.19.0.16932.dmg Source code(zip) Source code(tar.gz) Am I looking in the wrong place?
  2. Lovely images, Avani. Great job! I tried to make a 3D view out of the images, but the planet hasn't turned enough between them so the 3D looks very flat. I suppose you need images taken about 15 minutes apart for that trick to work. Thanks for these wonderful images.
  3. Two awesome Saturns. The IR shows more details in the atmosphere, so I like that one best. Thanks!
  4. Hi Pierre, it's a wonderful image. Looking forward to tomorrow's, with Saturn.
  5. The 8mm BST is going to be much better than the 10mm kit eyepiece. It will Barlow just fine, but the magnification will be pretty high and the atmosphere may limit the 8mm's usability with the Barlow to nights of very good seeing.

    Mare Imbrium

    Beautiful sketches, very impressive!
  7. That Morpheus certainly found a warm home. Congratulations on your new eyepiece!
  8. Alcohol would do the job.
  9. My Bresser Everest ED 8x42 are the same as the celestron granites, just a bit cheaper (€125 less). I bought them on recommendations from bird watcher forums. Good binoculars, the dealer bought a pair for himself after we looked through them. But it was a few years back there may be better options today. Check the bird forums.
  10. Hi Avani, these are some really good images. Thanks!
  11. It's an excellent image, John. Thanks for sharing.
  12. The geometric mean between 5 and 9 mm is sqrt( 5 * 9 ) = 6.71 mm. This would give you equal steps in magnification of 34% from 9 to 6.71 to 5mm ES 6.7 82° would be your best in between fit, but I don't like that line due to its uncomfortable eye relief so I can't recommend it. I have a 6.5mm Morpheus which is really good at f/5. You might consider that along with the others you mentioned.
  13. This AZ5 would meet your requirements with just a little room to spare as it is rated for 5kg: https://www.firstlightoptics.com/alt-azimuth/sky-watcher-az5-deluxe-alt-azimuth-mount.html If you really want a photo tripod, remember that you need a beefy one and also some form of fine control that can handle the weight of the telescope with diagonal etcetera.
  14. Hesiodus A, my favourite concentric crater, stands out so well in the first image! And Dionysius looks wonderfully spiky with its rays. Thanks for sharing two great images!
  15. That's wonderful! Sorry, I couldn't help myself:
  16. Yes, Avani, Jupiter continuously rearranges itself, but one thing never seems to change: it is always upright! Would it not be extra nice if it had a decent tilt to its axis so we got to see views from different angles? Another thing that never changes is the superb quality of your images. If you looked in your archive, could you then maybe find images taken half a Jupiter orbital period apart, showing the maximum effect of the planet's tilt on its aspect?
