Description

An accidental capture of the wizard in all his glory.

I've just been trying to sort out my collimation and my focusser alignment.  It is way out of alignment (because I'd dabbled with it) and I had to revert back to the stock focusser and start collimating all over again  I used the wizard as the target as it was an available nebula in the sky all night.  Having done so, I have made some progress in collimation whilst actually capturing an OK-ish image.

Much more work to be done as my stars are still not right, however quite pleased for something I never really meant to capture

Title: BlurXterminator version

Description: I decided to see what a quick re-processing with BlurXterminator would look like.

I used 0.25 sharpening on stars and 0.6 on non-stellar. I should probably have used 0.5 on non-stellar as I think I have oversharpenned.

FWIW: the process I used was:
* dynamic crop of individual S, H and O images
* ABE applied to each (I was being lazy)
* BlurXterminator applied to all 3 channels using a custom PSF size determined by using PSFImage script
* I have a custom STF that I use which is a small to medium stretch which I applied to each channel to effectively achieve the same as a linearfit, but with the stars where I want them brightness-wise
* I did an SHO combination for one image, then a Foraxx combination for another image
* I did a 50/50 combination of the SHO and the Foraxx images
* Used StarXterminator to extract stars
* Used GHS, Curves transformation and ArcSinh stretch on the starless image to get it roughly where I wanted
* Used BackgroundNeutralisation with a range mask to get rid of colour cast that I had created on the background
* I used NoiseXterminator at about 0.4 on the starless image
* Used pixelmath to add the stars back in
