Omega Centauri – 2016-05-02

Omega Centauri

While in Namibia, I imaged the largest globular cluster or galaxy remnant we have, the ω Centauri. I used a rather dark 300 mm photo lens, and my Canon 1100D mod on the HEQ5. I have taken 36×90 sec, ISO 1600 at f/7.1, according to the EXIF. I may still have some unprocessed raws hiding in some folders on the external hard drives :)

NGC 6791 – 2018-06-19-20

NGC 6791

I also captured an open cluster, 12x90sec, ISO 800.

NGC 6791 [open cluster in Lyr] 9.5m ø10′ [wiki] [simbad] 750mm, 800mm, 1000mm

It is not particularly interesting for visual/photographic viewing, I chose it because it is on my local zenith – and accessible in spite of the heavy light pollution. It is however a cluster that fell onto the sensor of Kepler during its first mission, and it is a very very old cluster. At 13000 light years, it is also very very far away for a visible open cluster.

M39

During that same night, I imaged M39, 12x30sec ISO 800 frames.  (tovább…)

Messier 92 – 2018-06-19

Messier 92

I chose an unlikely location to image M92, I thought since it was in the zenith, I imaged it from the city. So I used my equipment, the N 150/750, Baader MPCC Mark III, Canon 1100D mod, HEQ5 with no naked eye Milky Way. I acquired 11×90 sec ISO 800 frames. Then began the hunting.

To my surprise, many faint, >16m galaxies are visible too, in spite of the heavy light pollution.

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.).
