Description

Taken with my Optec Lepus 0.62x FR and newly repaired Canon 50D. The presence of hot pixel streaks seems to imply that somehow the sensor characteristics have changed even though the only repair was the replacement of the shutter. In addition, there is a dust-bunny in the top right. Need to redo the flats or clean the optical path (or both).

The real purpose of this 'close-in' image of M33 however was to check out the new software solution I have employed to correct for flexure issues I've been plagued with. Many of my previous uploads have had some 'eggy' stars and it was only recently that I have attributed this to flexure between the guide scope and the main scope. As you can see the stars are nice and round even with the 180sec subs (not perfect, but much, much improved over previous imaging at > 120sec).

The software solution was to use Metaguide as the guiding software and FlexRX to correct for the flexure. I am very pleased with the results!
