Thanks Kevin,
It's amazing what you can do from the suburbs.


I did a couple of interesting pics.
I use a 1222 mm focal length 8" Newt.
This gives me a 0.91 arc seconds per pixel ratio with my KAF 8300 sensor = 5.4 micron pixels.
The seeing is never that good - typically 2.5 to 6 arc seconds.
On the night these images were taken it was poor at about 5 arc seconds.
Therefore binning at 1x1 was of no use to get more detail.
Also - I chose binning 2x2 after seeing the noise around the horsehead in a 10 minute
sub frame of Ha at binning 1x1.

I produced these pics from the original 10 minute frames.
They were stretched in FITs Liberator & further stretched
in Photoshop to try & give equal justice to them.
There were no: darks, flats or biases applied.
This is raw data at original pixels.
The only conversion is to JPG but they don't look any different to the Tiff files.

Question - should I only image with binning at 2x2 from now on?

What do others think about this question?

cheers
Allan
