now imaging m101

Has anyone done any rgb images of m101. I have just taken the red set of images and they are fairly dead looking. I kept going back to the scope to check for dew. Green images seem to be fine. Red may be lacking in this galaxy but not sure . Might try some h alpha after blue images.

I took some mono 101 images last night - its a tricky subject at the best of times - seems to have a fairly low surface brightness (compaered to say M51).

Dave,

It costantly looks blurred in the sub frames but the red images are worthless so I am now taking some H alpha to see what the result will be.

Kieran - don't throw out the red frames just yet! See what happens when you combine all the subs. It may turn out OK.

still have them but guiding is giving me jip at the minute so losing a lot of frames
