Managed to get rid of green gradient but at cost of loss of detail. Used gradient layers in Photoshop.
Here’s my first pass at processing some Mars image runs. I’ve been a bit too gentle on the processing this time round so I’ll go through again. The polar cap and some of the surface is starting to appear nicely. I need to get a better Barlow though.
The data set I’ve got to work with is 3 image runs totalling 15000 subs, taken with ZWO 170MC and Celestron 8SE with a x2 Barlow
The picture is a little noisy – but worse still is the nasty green light pollution gradient – everything I try to remove it also takes out the nebula – suggestions please!
Here is my first attempt at the Western Veil Nebula. I am actually hoping for clouds tonight, need some sleep.
This target was a tricky one indeed. I have found the reflection nebulas, small and difficult to get lots of detail. This was my first attempt at this particular nebula. I have only 1hr55mins of 5 min subs. I feel I need 3 times this amount of data to get more detail, so will add to this over time.
Focus point on Sky Watcher Equinox 100mm+Tele Vue 75mm extension tube:
= 74mm Quark H+Daystar interference elminator+QHY ASI174MM.
= 44mm Quark CaH+Daystar interference elminator+QHY ASI174MM.
