M31 2ndAug-3rdAug Using Focal Reducer - Removed Colour From 1st Image

[jcm]

Again skies not good - haze and moonlight.

130mm APO , 0.8X(2") focal reducer , 20X2.5min , 350D 800 iso.

This is really a test of the reducer. Quite please most stars are sharp and round. Some small black marks - dust etc? Did not get the framing quite right , but OK for the test.

Will now have to start doing some flat fields. Anyone got some info or a link to a step by step guide?

That's a corker of an image John.

Whatever you put into the optical train, it did the job good.

I am glad the end result was OK - the reducer cost "an arm and a leg"

Nice shor John.

M31 is a big 'b****r', and your focal reducer has contained it nicely.

Nice one John. That's very impressive with the moon being up to no good.
