Sundry Lunar images 11th-16th Jan

Tommohawk · January 22, 2022

As a DSO fan, I'm beginning to wonder if there's any meteorological correlation between there being clear skies, and a full moon???

Anyhow, I thought I'd give the moon a punt with my Quattro and Omegon 385, with a 5x powermate (working at about x4) - had only used this on planets until now. Mostly seeing wasn't great - my neighbours roof gives off some heat I think and mist encroaching too.

A lot of this was just experimentation with different file types - AVI vs SER - and I made some interesting discoveries. Main thing is that with OSC the undebayered SER file size is much smaller cf AVI - which is handy given I ripped through 160GB of data!

My feeling is that the Quattro mirror doesn't quite perform to the highest standard - sometime I think I'll replace it with something better, hopefully before Jupiter and Mars come around. (see my want ad for a 250mm mirror!)

All slightly haphazard targeting and some duplication. The terminator stitch is a right mess!. One thought I had on this is that I'm routinely oversampled, and apart from possibly losing resolution this makes for many more frames than necessary when doing mosaics. Neil has posted some wonderful lunar images which are a bit undersampled, and he has way better quality images and only 9 required for a full disc mosaic! (You need to zoom in on his to get all the detail.)

Thanks for looking - labels are above respective image!
