M81 & M82 Drizzle (Re)processed
May 17, 2017 20:27:14 #
My previous M81 and M82 images were undersampled so decided to 2x Drizzle process the subs in PixInsight to see if I could pull out more detail. The end result for M81 is not too bad. M82 could have done with more subs and less cloud/moonlight (and a wider crop)...

Never happy with processing results so I redid these two galaxy images. Maybe better? Maybe not?
I think I'll throw M82 in the garbage and shoot new subs w/o cloud and moonlight!!

Very nice job Brian. I don't think I have seen a shot of M82 that close here before. Did you use a Barlow lens?

Now wait a minute...
Very nice!
But aren't you the guy that told me not to be so fast about throwing away files?

Yup, that was me AND I decided to give it one more try. This time I used Registax to align and stack the subs. I can almost live with this result...

No Barlow used. In fact I used a 0.6x reducer on the AT8RC to get a 960mm focal length (and an acceptable f/4.8).

Yeah that's a push between power and f/stops. And your new stacks really clean up the shot.

For the sake of completeness (consistency? curiosity?) I've reprocessed M81 in Registax as well...
I prefer my previous version.

I hope to be able to do as well as this someday when I grow up:

I first saw this image on DPReview.com. The creator of this image is Michael S, who lives in Austria. He did this with a 10" newton reflector and a Nikon D5300a plus about 4.5 hours of integration time. I find this image just jaw dropping in what he was able to do. I've looked at his other images, and this is no accident. I don't think we needed Hubble. Just supply Michael the RA-Dec that they want to see, and turn him loose. Click on M82 and watch it go large!
