Description

Allot of upgrades behind this image after a break, so this was more or less a test with all the new stuff. The background is not yet optimal (purple blotch) but I will look into it for a updated version. I had allot of gradient to remove, will look into my second data set from last night how that works out and might redo this one.

Updated technical procedures:

- Using dithering (aggressive because of my OSC-camera).
- Longer exposures (300 sec) and higher gain (20).
- Using new full frame Riccardi reducer with Starlight Xpress 9 slot filter wheel.

Seems to have solved quite some issues which I still was experiencing.

Next will be start using my monochrome camera, ZWO ASI 1600 MM PRO, since my filter wheel is connected and working great.

removed purple blotch from the background. Was actually quite easy using PixInsight. Created a mask using range selection so I could exclude all the signal, then applied massive de-saturation to the background. Much better.

C

tiny crop on top just to make it a little bit more perfect :-)
