NGC 6888 Crescent Nebula – 8 minutes

NGC 6888 (C 27) Crescent Nebula

The main target of the night was the Crescent Nebula. I imaged it with my usual telescope setup, N 150/750, Baader MPCC Mark III, Canon 1100D mod, HEQ5 with the resurrected guiding camera. I took 15×4 min ISO 800,  and just for fun, 2×8 min ISO 800. To my surprise, the sky allowed this, having almost no background fill inspite of the long exposure.

NGC 6888 Crescent Nebula

NGC 6888 Crescent Nebula, 50×45 sec

I found some forgotten raw material I collected during the summer. Tech details show the frames were more like tests than a serious attempt at photographing this object. Nevertheless it was worth the shot.

NGC 6888, also known to amateurs as Caldwell 27, the Crescent nebula is a faint, 10m deep sky object in Cygnus, near the well known Sadr (γ Cygni) region. The nebula is blown by the Wolf-Rayet star WR 136 (HD 192163).

Astrocamp at the Rotunda Pass

Astrocamp

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…)

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.).
