Another day with rain, wind and clouds with 0% change of any sunshine.
Temperature dropped below 10°C. Thats why people wearing wintercoats..in June..jezus fcking christ..
Autumn, Winter, Spring 3 seasons of shit weather.
Considering about moving to another country in the Mediterranean area.
Spain seems to be immume for rain.
*sigh*
I feel you, dude.
Maybe some of you were asking themselves why i didn't post any offtopic space images in the last weeks/months...
Well, i was trying to push the edge a little bit and capture a rather dim, nebulous object, using a telescope that is rather darkish in terms of illumination, with two different filters and convert the resulting stacks into a true Hubble Palette color image. As if this wasn't enough, i had to wait for weeks for clear nights, just to get the minimum amount of light (2 nights, about 5 hours each) to pull this off.
After combating several problems at processing the images from the combination (dim object, dark optics, high magnification) night after night, i was finally able to improve an acceptable result of IC1396, the "Elephant Trunk Nebula" in Hubble colors:

UPDATED version:
After all, starting off by building a DIY autofocus for the 1500mm telescope, it took me nearly two months to pull this off because of nightly weather conditions.
EDIT: There's that red blotch that shouldn't be there, though. I have to look at the data and workflow, to find out where it's coming from. It could be stray light, lens fogging, too much background reduction in the blue and/or green channel (mapped to Oxgen-3 and Hydrogen-Alpha radiation wavelengths), because Red is mapped to Sulphur-2 radiation, and this wouldn't be so strong in this place of the nebula. Actually, S-2 is quite weak here, so the image is mostly tinted green-ish to blue-ish.
Seems to be my Sisyphos target, but i need work like this going on to wrap my head around.
EDIT2: Added the corrected pic. Et voila!
