Description

This is a test image from the other night while i was getting acquainted with my new guiding setup. I was extremely chuffed when i saw my first ever 5 minute exposure roll in with perfectly round stars

Was also a great opportunity to test one of 3 aperture rings that i recently received. When used in combination with the lens set wide open, it steps it down to f4. Except instead of those nasty star spikes the EF200L produces, i get nice round stars! Excellent. I think i will be using this ring for all my images in the future, i see no reason not to so far.

Only managed 45 minutes on this trial run as the Moon was rising but now that i know what i'm doing, i'm really looking forward to some clear nights. This image also shows many other galaxies other than Markarians Chain itself. Not counted how many yet though!
