Back at the clearing of the summer back log - day 7

Yet another object I've already shot.  Here is M102, a small, edge on galaxy.  This time I decided a side by side comparison as it was taken with the same scope and different cameras.  The canon 7D is on the left and the SBIG STF-8300M on the right.  They were taken in different conditions and different nights.  Things that jump out at me are the image scale on the Canon is larger as it's 0.55''/pixel whereas the SBIG is 0.7''/pixel. Also, the Canon 7D is shot in bayered color mode and the SBIG being monochrome is only shot in clear / luminance channel. The other thing to note is that the integration time is quite shorter on the SBIG. You be the judge.  

Here's the recent work on M102

And the old shot

And the side by side

Not meant to be a real or honest comparison, just my happenstance results.

I've always loved facts, provable facts of nature and things concerning science.  

Over time, I found that most facts are mostly reference and it was the creation of and discovery of new things that intrigued me.

"A good friend once told me you are our memory
without them we equal nothing
And all I can see is the place I wanna be
Suddenly my life was so free
Leaves at my feet, blown to the ground
their echoes are reaching my ears
Nights coming fast, suns going down" - A7x
