Baby Eagle Nebula – LBN 777

Baby Eagle Nebula, ~15×4 min, ISO 3200

At Curmături, I imaged the Baby Eagle Nebula, a fairly hard target, visually invisible through our telescopes. I obtained 12×4 min at ISO 3200 and some other frames (one at 10 minutes, ISO 800), with my usual gear N 150/750, Baader MPCC Mark III, Canon 1100D mod, HEQ5, autoguided.

Nice catches are some fainter galaxies, the UGC 2931, MCG+04-10-015, UGC 2946.

Curmături Astrocamp, autumn of 2017

I think, the best observation night I’ve ever had in Europe, was the night of 2017-10-20, at the Curmături Cabin, in Alba County. There was some airglow, but not a cloud, steady seeing, 21.4m-21.8m sky (the lamp posts were turned off for us, and the few neighbors were kind enough to limit their outward shine), no wind, electricity from the power grid, negligible to no humidity (no dew heaters needed). Although only one night was usable for astrophotography.

I used my usual gear, the N 150/750, Baader MPCC Mark III, Canon 1100D mod, HEQ5, autoguider.



M33, the Triangulum Galaxy- astROmania2017

M33 Triangulum Galaxy

During the astronomy camp, I turned my telescope multiple times towards M33 with little success. Although it seems like an easy target, the weather was working against me, or perhaps the planets were simply misaligned :P Finally I settled with 18×5 min, ISO 1600, with the modified Canon 1100D,  N 150/750, Baader MPCC Mark III, HEQ5 with the resurrected guiding system. And I say settle, because the collimation was visibly off. So I had to invent a way to correct it, and I came up with a very crude php script that basically says: if you are a bright star, show me your center of gravity, then let me go around you and put some of your misaligned light to the other side. The outcome was far from a success but spared me from doing it manually on each and every star.

Meet NGC 7293, the Helix Nebula

NGC 7293 Helix Nebula, 57x3min

Helix nebula is huge when considering its angular size, but as a visual target it’s challenging to say the least. Its estimated distance is 700 light years, which makes its size about 2.5 light years. It is one of the closest planetary nebulae.

I took 57×3 min of it, at ISO 1600 from Dângău Mare on 2017-09-15 with N 150/750, Baader MPCC Mark III, Canon 1100D mod, HEQ5 with autoguider.

Bubble Nebula with M 52 – astROmania2017

NGC 7635 Bubble nebula and open cluster M52

As a secondary target, I imaged the Bubble Nebula – M52 open cluster duo. I obtained 7×5 min usable light frames with the N 150/750, Baader MPCC Mark III, Canon 1100D mod, HEQ5 at ISO 1600 (and sub zero temperatures, summer :P). The area in Cassiopeia is fairly rich – more and longer expos – but the equipment was about to fail due to the extreme weather and power issues. Maybe next time. To my surprise though, I could tame the raw frames to obtain this picture.

Again, a target I didn’t really care about. A quick shot of C/2015 ER61  in the morning of August 19. More details in this article.



Supernova SN 2017eaw

SN 2017eaw

In the astROmania 2017 camp, I didn’t really care about the nowadays visible supernova in the Fireworks Galaxy. I just tried (and ultimately failed) to collect enough photos for a beautiful picture. However, when I came home and started typing these articles, I realized I have an old post about this galaxy. Back in 2013 my Newton scope + DSLR setup was only a few days old (EQ3 mount, no MPCC, unmodded camera, shot in JPG, unmodded tube), so those pictures qualify as first lights. I also remembered that, due to human error, those pictures might be lost forever, having only the placeholders even in the wayback machine version of the old website that article used to be on, and not the actual pictures. I am lucky (cursed actually), cause I turned out to have a backup of a backup in a very obscure folder of an obscure drive I have actually forgotten about. Noteworthy that other than being my own data, those pictures have close to zero value. (tovább…)


Minor targets – astROmania 2017

C 12 with a supernova

During nights with modest sky, I chose to shoot some objects marked as plan B.

While in the camp, I imaged NGC 7789 [open cluster in Cas] Caroline’s Rose, Caroline rózsája, Karolina rózsája 6.7m ø25′ [wiki] [simbad] 750mm, 600mm, 1200mm gathering 16 expos from 2 to 5 minutes, ISO 1600 with N 150/750, Baader MPCC Mark III, Canon 1100D mod, HEQ5, autoguided.



Cocoon Nebula – AstROmania 2017

C19 Cocoon Nebula

In the astROmania 2017 camp, one night I imaged the Cocoon Nebula. It is believed to be at about 4000 ly away, and be very young, at about 0.1 Ma (100k years).

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.).
