so this one is a composite of 3 images. the background was taken with a DSLR and AT6RC with a 0.8x reducer. the two galaxies were taken with an SBIG-8300M and an AT10RC. the galaxy images were registered to the wide image in pixinsight, then the Galaxies were merged in using GradientsMergeMosaic, overlaying the low res galaxies in the original image. unfortunately I clipped the background a little but there's no IFN visible anyway so it does not matter too much, although holmberg ix did suffer a little.

thanks - yeah they are pretty good performers for the price but they do have some shortcomings.

You can't deny this is the best variation of this joke.

great analysis. very sad for this country.
Michelle originally shared:
 
"...the Mayor of Oakland acknowledged that the Department of Homeland Security had participated in an 18-city mayor conference call advising mayors on "how to suppress" Occupy protests."
Naomi Wolf: The violent police assaults across the US are no coincidence. Occupy has touched the third rail of our political class's venality

I used a DSLR and never had luck with it.  I then got a QHY9m about 18 months ago and really liked the chip.  When the STT came out with the 8 position filter wheel and OAG built in, I knew that was going to be my new camera.  And so far its performing better than I had hoped.
