NGC2359, Thor's Helmet. RC8 third light...
Hello everyone!
Well after what seems like an eternity, I actually have something new to post!! Last night, Thursday night, I set up my scope for what would hopefully be a good night of imaging. But it didn't take long for the gremlins to raise their ugly heads!
I had trouble drift aligning, there was some flex in my rig and I was using a new version of EzCap for my QHY8L. No dramas there except that on my very last sub I realised I was using the default Gain/Offset values rather than those that I had calculated. I also hadn't done the auto crop so my images didn't match the size of the darks in my library. In other words, the following image does not have darks applied. However it does have flats and dark flats.
Anyway, enough of the complaints, here's my rendition of NGC2359, Thor's Helmet. I spent some time trying to get rid of what I thought was background red noise, until I checked some images on the web and realised it was nebulosity! This image is 2 hours worth of 10 minute subs taken from my backyard in Brisbane - I've also attached an light pollution map of Brisbane (I'm the red dot) which illustrates how important my UHC-S light pollution filter is!
Stacking in DSS, processing StarTools, final cosmetics in GIMP.
Any hints, tips, thoughts or donations gratefully accepted!!
Cheers,
Mario
