Last summer Wim @wimvband I entertained ourselves with processing freely available data (subs) from the Liverpool Telescope, since Sweden is too light for AP that time of the year. I was just told that one of my attempts on the Bubble made today's APOD! Yes I know, the data is from The Liverpool Telescope, a 2 m RC scope on La Palma, so not collected with my own stuff, but I did the stacking (Nebulosity) and processing (PS).
Now I just have to come down to earth again...
The result of one of my imaging sessions from Kelling Heath Autumn Equinox star party NGC 7635 The Bubble Nebula in Cassiopeia Imaged using Atik 314L monochrome CCD camera and William Optics FLT-110 refractor on NEQ6 Pro SynScan mount 10 x 300 second subs in H-alpha
Hi here's an image I took over the last couple of weeks. Its 30 x 10mins of Ha and 9 x 10mins each of RGB. I'm relatively new to AP so still getting to grips with everything (especially processing).
I've read on here that using Ha as a lum file is not advisable so would really appreciate any advice on combing Ha with RGB in this type of image. Would adding Lum, Oiii or S data help.
All feedback would be gratefully received.
My yearly four-day autumn sojourn to Kelling Heath yielded only one picture this year. I used my Astro-modified Canon 1100D to capture 28 x 300 second subs of the area around M52 in Cassiopeia. The camera was cooled down to just 6 degC by my homemade camera cooler and this certainly led to a relatively low-noise image.
The cloud we had led to the brighter stars having large haloes around them, which I had tried to reduce a bit.
