Title: M101 first light SW120
Post by: Fay on Mar 07, 2010, 13:58:18

18x480. SW120, Atik 314L, cls filter, 0.8fr, flats.060310. Did some RGB, but not enough, had to ge what Lum i could because of cloud.
This has been a nightmare to process as it is so long since I have done any, especially galaxies, that I had a brain malfunction regarding processing.
It is something you have to keep on top off, easy to forget little tricks etc etc.

I am sure there is a lot more I could do with it.
Clouds were scudding around & the sky was quite bright as I had to start with M101 quite low.

Thanks Mac, so hard to remember how to do what with the processing. It is something you really have to practice with, even on old images just to keep up with it.

That's a hard one to practice on Fay but you've done very well as it's very faint.

Very nice, Fay. I wish I was as out of practice as you!

Nice one Fay. I find processing very hard. If I got a result as good as yours I would be very happy.

Focussing is spot on and you've captures lots of detail there.

An excellent first light.  What's the focal length of the SW120?

900. I used the 0.8 focal reducer as well
