Took these Saturday night under clear light polluted skies with a moderate Jetstream playing with the seeing, so they lost the detail I can usually capture under better conditions. SkippySky was right again but I decided to set up in hope that conditions were going to be better.
Due to the average seeing, it was hard to establish whether or not the Mars dust storm is starting to clear, I think I can just see some hint of detail coming through so we wait in hope.
I put the 8 inch Newtonian through it's paces because after giving up on the planetary, I swapped the unmodded 550d over to the modded 550d and got this 10min integration exposure of M20 just to finish off the night. I took 40 x 40 second subs but had to ditch 25 of them due to bad tracking errors! I think I may have had the EQ5 mount weighted to the west which caused the problem, added to that the RA motor seems to be jamming a bit.
Exposure details: Planetary, 8 inch f5 Newt with 12.5mm eyepiece + 2.5x Powermate, Canon unmodded 550d, Movie Crop mode.
M20, 8 inch f5 Newt at prime focus, modded Canon 550d with UVIR cut filter, 15 x 40 seconds 800 iso.
