I am posting my photos in an effort to contribute to site traffic even if minimal. I have another forum where I post stuff so posting here is not to satisfy some need to publish.
I hope someone gets a kick out of following my progress to master the game..years off yet.
This image is the same as the last one..it is known as The Fighting Dragons but catalogued as NGC 6188...it is an emission nebula about 4000 light years away and is a star forming region with some young stars probably only a couple of million years old.
the image above was the Hydrogen Alpha data collected to that point which was only a black and white image that I coloured in via Photoshop..a terrible thing to do and no doubt frowned upon by folk at the pointy end of the game.
the image below not only has additional Ha data but data in red, blue, green, luminance and oxygen..I thought I had data for sulphur but it seems to have vanished.
there is probably thirteen and a half hours of data in the one below and has taken me over a week to process because my stacked files were rather big (one point six gig) and the lap top crashed many times before I could crop and bin the various stacks..usually nearly at the end meaning back to square one..but happily one run it did not crash giving me manageable files that were manageable by my lap top. I actually have my desk top here now but it also had problems..but faster..it still played up.
Anyways I tried various times to process and nothing seemed to be anywhere decent and although this one should be better its not..so I will post it and forget about this object for a while..the captures were thru only an 80 mm refractor so I am very happy with the detail. the mount was an heq5 pro without guiding so exposures were one and two minutes ..the Ha had 250 subs maybe six hours via short exposure..I use the Hubble colour palette to map HA to green, and oxygen to blue and just let the colours run wild really but its is probably not conventional.
and for those who may look here but not at rivers latest gravity wave length thread I include a photo of my new observatory which although cost me a small amount of cash I regard almost as a gift.
