sh2-240 in bits and pieces

[pc387]

Can't remember if i've ever posted a photo on this forum before; but here goes:

I've tried to reconstruct this based on files obtained between 2014-2018,; never having the good fortune to chase this target  for a full capture sequence overnight, the latest captures were last week under very windy and sometimes cloudy conditions.

Details as follows HA; SII; OIII 6x600 secs each 2014

HA; SII;Oiii 6x900 secs each 2015

HA; SII; OIII 6x 900 secs each 2016

HA; Sii ;OIII 3x1200 secs 7_Dec_2018

HA:SII 4X1200 secs 13_Dec_2018

 

Camera ATIK 460 EX Mono; ATIKEFW2; Badder (H,O,S) 7; 8.5; 8.0 nm filters; Nikon 180mm f.2.8. Combination of SW NEQ6 and Paramount MyT.

No Darks; Occassional Flats (as per learning curve over a 4year period)

Processing; A bit of a challenge in Pixinsight, trying to use image integration and gradient merge mosaic

Very nice image of a really challenging target.

I've started on the same journey this year and so far only collected about 4 hrs of Ha and 2 hours of OIII but my image is still very indistinct. You've managed to reveal lots of detail and structure. Very nice job.

Thanks for sharing.
