A very late Cone


Recommended Posts

A high 90% Moon, a slightly dodgy sky, and a rapidly sinking target... makes for perfect imaging conditions? nahh! Didnt want to let that stop me though :)

So this is probably the last bit of Ha for a while, until Cygnus swings around again (where I'll be off to the dark site with the 135mm f2). I pretty much guided this one into the fence, and you could see the deterioration in the data as it slowly sank into the murk, but I stacked the lot anyway for what its worth. I also popped the camera into 2x2 bin to make the most of the short(ish) run.

One problem I ran into though was "walking noise", and my usual method of calibration/stacking wasnt working so I went for the full monty of darks, bias, flats and dark flats - which seemed to do the trick nicely.

Thanks for looking :)

Thanks guys :) 

I'm just a bit stumped on what to go for next, and whether it's worth dragging the 8" out to the dark site - or stick with the lens and do some of the IFN around polaris or draco. The easter Bank holiday looks promising, so I'll have a think about it.
