Still learning... Pleiades

[gaz81]

Had a go at Pleiades... still leaning 🙂  

With Skywatcher 72ED, Sony A7II on a skywatcher AZ GTI in EQ mode.

15 x 4 min subs.

I did have a generic Sky watcher light pollution filter on, but have a feeling I lost data due to that... only my second real attempt at long exposures like this though.

I feel I have over processed, but seems a difficult subject due to the bright stars in the middle and still getting my head around PS.

That looks a really good capture at 4 min subs - good detail and nice round stars. Perhaps a bit too strong on the blue in colour balance?

Ahhh... thanks for the feedback. 
 

Thought they were ment to that saturated, can if hard when looking at examples of other peoples edits online 🙂 

Will gave it a tinker. 
 

was pretty good doing an edit while watching an Astrobackyard vid. Like editing individual colour channels for noise etc.

I think there is more to this data. Here is quick extract of green channel as luminance and a bit of stretching:

Once gradient is removed and color calibrated and applied to this luminance, I think there could be rather nice image.

Your original rendition is too blue and stars are without color - as if whole image is monochrome with a blue cast over it. Data is not like that - there is quite a bit of red and yellow in there as well.

4mins with an AZ GTI is pretty impressive. Even in EQ mode.

Cheers. Waited until SharpCap gave me ‘Excellent’ in polar alignment before I started.
