40 year old Big Bertha tries to shoot the Cygnus Wall (in 25minutes)

Updated: Jul 22

There was so little wind so I chanced my arm at lucky deep sky duo band imaging with Bertha and her huge unguidable clockwork drive mount. Really you need 10 minute exposures for this kind of imaging but Bertha only managed 7.5 seconds before the stars went wobbly. So gathered 200 x 7.5 second exposures... 140 of which were usable.



I think that's really good considering the limitations. Next time I will try polar aligning better to see if I can get longer subs.

Then I put Bertha to bed under her stylish pebble shower curtain cover thing.
