M51 and 80ED first light

[Bagnaj97]

I recently bought a Skywatcher 80ED and I added an Altair Astro 0.8x reducer/flattener because it's almost £100 cheaper than the Skywatcher 0.85x. This is the proper first light (I had a quick visual peek between clouds with no flattener) and I'm pretty pleased with it. I was slightly concerned about flexure, not because of my 3d printed tube rings (they're very solid!), but because of the 3d printed extension tube for the guide cam to reach focus. This is just a quick stack and levels in DSS at the end of the imaging session and the colour balance is a bit red, I'll process it in PI later.

18x600s lights (ISO200), 20x flats, 30x bias

Scope: Skywatcher 80ED DS-Pro

Mount: Celestron AVX

Camera: Canon 450d (modded)

Guiding: ST80, Altair GPCAM, PHD2

 

The subs have all got this line down them, which I've never seen previously. Any ideas what could cause it? I hope it doesn't mean the sensor is on its way out...

Great Image, I imaged it once using a 200p but it's good to see the size with your scope as it's comparible to the 130pds I'm using now.

Finally had a chance to play around with the data in PixInsight, I still don't have much of an idea what I'm doing in it, but I think I've improved things. The colour balance is certainly better.

Beautiful widefield view. Looks pretty good, just a slight colour gradient to background.
