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.

Messier 13 – 2018-05-13

Messier 13

As a secondary target, I imaged the Hercules Cluster, M 13, NGC 6205, Mel 150 [globular cluster in Her]  5.8m ø17′ [wiki] [simbad] 400mm, 600mm, 750mm, 800mm, 1000mm, 1200mm, 1500mm . It came out somewhat unexpectedly well, considering M64. I acquired 8×180 sec and 7×90 sec, ISO 1600, with the usual setup, N 150/750, Baader MPCC Mark III, Canon 1100D mod, HEQ5.

 

The bright galaxy is NGC 6207 [galaxy in Her] 11.7m ø3′ [wiki] [simbad] [photo-planner] and the fainter yet still obvious is IC 4617 [galaxy in Her] [wiki] [simbad] [photo-planner]

Messier 64 – 2018-05-12

Messier 64

The Moon was no issue on 2018-05-12-13, since the solstice is very near and the astronomical dawn started earlier than the rise of the not yet new moon. The seeing was below average, and it was windy, but I managed to image the Black Eye Galaxy, Messier 64, gathering 15x240sec, 11x90sec with my usual equipment, N 150/750, Baader MPCC Mark III, Canon 1100D mod, HEQ5, at ISO 1600, the rest of the frames, almost half falling victim to the wind.

The object itself is fairly small for this equipment, measuring only 1/3 of the moon’s diameter, and the camera has a small resolution sensor – only 12MPs which though otherwise ok (large pixels gather more light, smaller guiding errors don’t really show up), leaves very little room for cropping.

M 64, NGC 4826 [galaxy in Com] Black eye galaxy, Feketeszem-galaxis 8.4m ø10′ [wiki] [simbad] 750mm, 800mm, 1000mm, 1200mm

The 37 Cluster – NGC 2169

NGC 2169, Col 83 [open cluster in Ori] 37 Cluster 5.9m ø6′ [wiki] [simbad] [photo-planner]  — from only two subs, because I wanted to see it with my own instruments.

Messier 106

M 106 and NGC 4217

The known location, the known setup, after six month of unfavorable weather, with clear hours at impossible times for a working class hero – same field trip as before. I acquired 9×5 min of light at ISO 1600.

The main objects on the image, sorted by brightness:

M 106, NGC 4258 [galaxy in CVn] 8.7m ø18.6′ [wiki] [simbad] 750mm, 1200mm

NGC 4217 [galaxy in CVn] 11.6m ø5.2′ [wiki] [simbad] [photo-planner]

NGC 4248 [galaxy in CVn] 13.2m ø3′ [wiki] [simbad] [photo-planner]

NGC 4231 and NGC 4232 (the twins)

NGC 4226

UGC 7356 (the faint one near M 106)

The Moon – 2018-01-31

There is nothing special about this date, no eclipse was visible from most of Romania, I simply imaged the Moon. I used the MC 102/1300 plus the Canon 1100D mod for the disk (13 frames) and the Scopium webcam for the details. Enjoy.

When to, what to – photograph

a year of the Lagoon nebula, observed from a forgotten corner of Transylvania

You may already know my astronomy catalog search engine, the DSO. It includes all the catalogs we amateurs use: the Messier, Caldwell, NGC, IC, Arp, SH2, Collinder, Melotte, Abell planetaries, it even grabs the list of exoplanets from a wiki page to always be up to date. But this is not all. It includes some ugly formulae to know about the position of the Sun and the Moon, and do some math based on  the geolocation of the user. The DSO however is more like a text mode tool, or an API. It is good to just look up what Messier 51 or NGC 7000 is. Anything more complex requires some heavy wizardry even I don’t master and need to look up in the help I fortunately did write.

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.).
