Title: Gecko Nebula Sh2-126 2021 and 2023 combined
Post by: Carole on Oct 06, 2023, 16:50:34
I took this image from Home in 2021 using a Hutech Idas LP filter instead of Luminance.
I recently took a widefield of the same image with the Samyang lens at DSC.

Decided to try to combine the data for a "close up".

Data from 2021:
Atik460EX and William Optics ZS71 on HEQ5
Idas filter (Lum) 450sec subs x 32  = 4 hours
Ha 6 x 600 secs
RGB total of 1 hour combined (binned)
Taken over 3 nights
Total imaging time 6 hours.

Data from 2023
Samyang Lens 135mm @ f2.8
Atik460EX
Lum 1h 40mins
Ha 1h 40mins
RGB 1h 40mins
Total 5hours

Total for both = 11 hours

Combined image
