I'm very happy with it so far, though the weather hasn't been particularly cooperative. Lower noise and higher resolution compared with my previous OSC camera.

Moving quickly! We had a very interesting talk on 3I/Atlas by Darryl Seligman yesterday at @astronomyedinburgh.bsky.social . It's available on YouTube and well worth a watch: www.youtube.com/watch?v=zQUM...

Very nice! I bought a mono IMX571 recently along with LRGBSHO filters, and am looking forward to trying these two.

Really nice. You can zoom in and see loads of detail brought out by the Hubble palette.

If you zoom in on the Dumbbell Nebula, you can just see the central white dwarf star. Amazing for just a few minutes!

@e-astronomer.bsky.social and @astroroyalscot.bsky.social have set up the Scottish Youth Telescope Network to place smart scopes (S30s and S50s) in outdoor centres visited by Scottish pupils.

And here’s the M31 image straight from the Dwarf3. About 40 minutes of 15s exposures, straight from the Dwarf3

Just had a quick look at the Lunar Quick Map. No obvious mountains there. There's a crater near Adams that may be what you've caught. See the map here: bit.ly/43lGnZL

The crater just west of the silhouette is Adams, so what you've pointed to may be Adams D. Petavius is west of that with the rille in the crater floor.
