The Milky Way in Cygnus

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.

NGC 7000 North America (the December 2016 version)

I once more reprocessed the North America raws I have from 2015.

The Milky Way in Cygnus and Cepheus

The Milky Way in Chepheus and Cygnus

The Milky Way in Chepheus and Cygnus

I imaged the Cygnus-Cepheus region of the Milky Way characterized by bright emission nebulae, countless stars and dark clouds of interstellar dust. Deneb with NGC 7000 North America and its neighbour, the Pelican, and gamma Cygni with the nebulae rules the upper right corner of the frame, while on the left the much fainter IC 1396 holds the Elephant’s Trunk. Downwards from the center the Cocoon Nebula ( IC 5146 / Caldwell 19) is also visible, amongst other fainter and less prominent deep sky objects.

This time I used the cheapest lens I have, the Canon EF 50mm f/1.8 II in manual focus mode, which is held tight and in focus by some hard wire I put on it. Although dialed to F/4, it performed pretty well, given the circumstances. In order to avoid having bad corners, I made a mosaic with big overlaps. So the HEQ5 mount held the Canon 1100D mod camera on a ball head, with the lens. 50×3 minutes, ISO 800, F/4. I also used the healing program – source code below.

NGC 7000 – third approach

NGC 7000 as I processed it on 2016-09-22

NGC 7000 as I processed it on 2016-09-22

Back in December 2015 my modded camera had the first Ha-enhanced light. As I keep most raws, I dag up those in order to test whether my processing abilities have evolved. One aspect is the healing algorithm I wrote to handle the dense star fields – ie: remove all highlights and their immediate context and fill the holes from the remaining image data. Canon 1100D mod, 20×110 sec, ISO 1600, Canon 200mm f/2.8 lens dialed to f/4.5, EQ3 mount, unguided. More than fairly dark sky of a place near Dangau Mare, Cluj county, Romania.  (tovább…)

NGC 7000, gamma Cygni, M27 (2015-09-13)

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.).
