Title: The Trapezium from last night
Post by: RobertM on Mar 17, 2009, 21:07:56
Conditions were "FAIL" but I wanted to try the 9.25 after it had been off for a service at BCF, and this is one of the test images I took.

C9.25@F10 unguided 9 x 30s with Canon 450d, this is the full frame resampled to half size.  No flats,bias or darks or field corrector.

Conditions: abysmal, lots of high cloud and through a pear tree.

And yes I know it's noisy - I only took 9 frames!
