The Pelican Nebula
A H II region of space. A H II region or HII region is a region of interstellar atomic hydrogen that is ionized. It is typically a cloud of partially ionized gas in which star formation has recently taken place. The Pelican is much studied because it has a particularly active mix of star formation and evolving gas clouds. The light from young energetic stars is slowly transforming cold gas to hot and causing an ionization front gradually to advance outward. (Wikipedia)
74 180s lights (3 hours and 42 minutes) taken over 3 nights with flats and bias. Dithered.
Telescope: - Skywatcher 130PDS Newtonian.
Camera: - Nikon D3100.
ISO: 400. Automated white balance
Filters: - Baader Mark-III MPCC Coma Corrector. IDAS D2 Light Pollution Suppression Filter
Flats taken with a Huion L4S Light Box and a white t-shirt.
Wireless Remote: PIXEL TW-283 DC2 2.4G.
Mount: - Skywatcher EQ6R.
Guiding: Skywatcher EvoGuide 50ED & ZWO ASI120MM-Mini.
Polar Aligned with SharpCap Pro.
Control Software: - Stellarium Scope, Stellarium, Poth Hub, EQMOD, All Sky Plate Solver, PHD Guiding 2 and PHD Dither Timer.
Processing Software: Stacked in Deep Sky Stacker and edited in Star Tools.
Moon: A waking crescent which was about half way there on day 3.
Light Pollution and Location: - Bortle 8 in Davyhulme, Manchester.
Seeing: - A mixture of average and good nights.
Notes: - Processing threw a new curve-ball at me for this picture. Not only is the nebula taking up the whole frame, but there was a line going through it. After a bit of forum help and a reprocess I have tried to remove it. Apparently it was caused by a reflection of something out of frame; as it pointed directly at Deneb, this is the likely candidate. The Star Tools Heal module did an OK job. This is a reprocess of the original I uploaded getting rid of a lot of noise and green although both is still present.
It’s been hot in Manchester for a little while now. Its nice to have a good few nights of work to do even if I don’t get many subs per night.
I managed to get a lead and adapter that will connect the mount to the shutter release in the D3100 so I feel my road to automation is getting closer. I tried to get NINA to work which successfully opened and closed the shutter once but then it seemed to want to find a picture file. Unfortunately it doesn’t seem to let me do that on the D3100. I’ve done some research and ordered a wifi sd card which I believe will give NINA somewhere to look. I just have to wait a month and a half until delivery date!
