Popular Post +Derbyshire Dave Posted April 10, 2022 Popular Post Share Posted April 10, 2022 Went up to the Chesterfield Observatory on Friday night.. the weather was poor, and it looked like it would just be one of those evenings having a chat, and maybe a beer! But the weather picked up, and the society's 19 inch scope was trained at the moon. Totally unplanned, but the lunar X and V were clearly visible, so I stuck the camera on my phone down the eyepiece and grabbed a few shots. Pleased to say that one or two came out OK... and that beer was still managed! Werisit, +Ibbo, +Glafnazur and 4 others 7 Link to comment Share on other sites More sharing options...

+Graham Posted April 10, 2022 Share Posted April 10, 2022 Nice grab Dave. Loving the photos of the scope. +Derbyshire Dave 1 Link to comment Share on other sites More sharing options...
Clive Posted April 10, 2022 Share Posted April 10, 2022 I've read (in a BAA short paper from 1996) that the 18" (457 mm) mirror is only 38 mm thick. In terms of mass to thickness ratio, that would be equivalent to making a 130 mm mirror with just 3 mm thick glass! +Glafnazur and +Derbyshire Dave 1 1 Link to comment Share on other sites More sharing options...
+Glafnazur Posted April 10, 2022 Share Posted April 10, 2022 that's a great shot, and the photos are great too, how old is the scope? +Derbyshire Dave 1 Link to comment Share on other sites More sharing options...

+Bino-viewer Posted April 10, 2022 Share Posted April 10, 2022 Thats a fabulous looking telescope Dave. I had no idea such a beast resided there. I've looked through the 24" at MSAS (Sherwood) a couple of times but this looks equally impressive. They use a fork mount on that scope though (on a wedge) rather than the German Equatorial you have here. Very impressive. Link to comment Share on other sites More sharing options...

Let's try and get a clear night. We're there every Friday night if you want to meet the gang, otherwise I have access myself . I'll be rusty in using the scope myself, so let me get a couple of practices in first +Bino-viewer 1 Link to comment Share on other sites More sharing options...
