The Milky Way in Cygnus

Cygnus is a great vista even to the naked eye observer. Along the Lyra, the Northern Cross rules the region also featuring a bright patch of the Milky Way which the experienced amateur astronomer knows is loaded with deep sky objects. I decided to take a deep wide angle look at this iconic part of the northern sky. Although the lens used is a toy compared to other takes, I am pleased by the results. Prominent dso’s in the frame: NGC 7000 – North America nebula; IC 5070, IC 5067 – the Pelican nebula; Caldwell 33, 34 – the Veil nebula; open cluster NGC 6940; although not obvious, C 27,  NGC 6888 Crescent nebula; IC 1318 the Sadr (γ Cygni) Region, and so on.  Photons collected on 2016-11-20, 21×3 min, Canon 1100D mod, ISO 1600, Canon EF 50mm f​/1.8 II @ f/4, HEQ5, used my star handler.

The gamma Cygni region, reprocessed on 2016-10-14

I wasn’t satisfied with the outcome of my star handling program so I rewrote it. The goal was to obtain an image that is as technically accurate as possible, while contains less artifacts and it is more appealing than the original.

I recorded with the Canon 1100D mod 21×150 sec, ISO 1600, with the lens Canon EF 200mm f2.8L II USM dialed to F/4, mounted on the HEQ5. The main feature is the red glow of the ionized hydrogen region around γ Cygni (the brightest star in the frame) with dramatic gaps caused by clouds of dark nebulae. The Crescent Nebula is also there. The object is also known as NGC 6888, Caldwell 27, Sharpless 105, and is a nebula blown by the Wolf-Rayet star WR 136 (HD 192163) expected to go supernova in the next 100k years.

Astrocamp at the Rotunda Pass

Dark Skies 2016 Astrocamp, Rotunda Pass

Amateur astronomers from Máramarossziget/Sighetu Marmației organized the Dark Skies 2016 Astronomy Camp at the Rotunda Pass. The area is one of the last remaining dark spots in the EU, so dark that the clouds appear to be dark brown/black.

The camp being meant mainly for visual observers, had no electricity, just a generator run in the evening, during the dinner to recharge the gadgets. It is the owner’s fault we had no running water at all, an issue I would have imagined for the savanna/desert in Namibia, not the Romanian countryside with a long estabilished cabin with as much water that my jacket got wet in a clear night. So much for the level of civilisation and decency. (tovább…)

As a plan B, I imaged the γ Cygni region with my usual equipment, the Canon 200mm @ f/3.2 Canon 1100D mod 32×30 sec, ISO 3200, HEQ5 PRO. Plan B, because I forgot to bring the screws which set the altitude/latitude of the mount, thus effectively criplling the mount’s precision. With some non invasive, duct tape improvisation I managed to take surprisingly good 30 sec subs at 200 mm, the 150/750 newtonian being out of question. This is the result.

Canon EOS 1100D @ Canon EF 200mm f2.8L II USM on motorized EQ3. After an alarming amount of frames showed trails I took the mount apart, cleaned it, regreased it, hope it’s better now.

Jól kalibrált monitoron mindegyik számnál elkülönülő árnyalat látszik. Ha mégsem látszanak, akkor a megjelenített képek színhiányosan rajzolódnak ki. A monitort valószínűleg kalibrálni kell.

You should see distinct shades for each number. If those shades are not clearly visible, the displayed pictures will lack accuracy. Your display most likely needs to be calibrated (brightness, gamma, contrast etc.).
