M33 / NGC 598 – Triangulum Galaxy

is a spiral galaxy 2.73 million light-years (ly) from Earth in the constellation Triangulum. It is catalogued as Messier 33 or NGC 598. The Triangulum Galaxy is the third-largest member of the Local Group of galaxies, behind the Milky Way and the Andromeda Galaxy. It is one of the most distant permanent objects that can be viewed with the naked eye. The galaxy gets its name from the constellation Triangulum, where it can be spotted.

This is my first approach to this galaxy. I’ve collected light frames with few different sessions. Photos taken on 2019 at Zwardoń and Bieszczady during PTMA rally.

Equipment: Canon EOS 6D, SkyWatcher Newton 1000/200 [mm], F5, coma corrector, NEQ6Pro.,

  • Composition: Astro Pixel Processor,
  • Processing: GIMP + plug-ins (Linux).

Moon – first quarter

My first moon photo. It took me a long time to take a photo with moon, but somehow I couldn’t get together in myself with this topic. When I collected the light frames and movie, I delayed again myself to get to work with it. Maybe the reason was that to take photos of the sun, moon or planets is a totally new topic for me. Finally I took together in myself, sat down my ass on chair and the fun with hard work has began. During my struggles with the AutoStakkert program and photo processing, some additional were created, let’s call it …. never mind for now. When it’s ready, you’ll find out.

C/2019 Y4 (ATLAS) Comet

Comet with a near-parabolic orbit, which rather certainly will be visible to the naked eye at may this year. Was discovered by the ATLAS survey on December 28, 2019. It is possible the comet may be visible to the naked eye sometime in April or May 2020. It will reach its nearest point to Earth on May 23 and come to perihelion (closest to the Sun) on May 31.

I must admit, without beating, that stacking and processing of the comet was a very difficult topic for me. It was a challenge I didn’t have in astrophotography till now. My basic tool for stacking astrophotography images has completely failed. Quite rightly, because the APP has not (yet!) implemented the necessary functions for stacking photos containing comets. A standard stack of photos taken in APP always gives the same result, nicely aligned stars and the comet appeared as a blurred galaxy.

Below you can find some photos, that were created during testing various configuration options available in DSS. Each photo has its own beauty, so I decided to show them all.

Below is a stack with orientation for a comet with the great “HALO” occured.

After digging up the Internet resources, it turned out that DSS has the necessary functions already for stacking images, containing a comet. I have to admit it’s pretty good at it, if you stack light frames aligned for comet or star-oriented images. BTW the APP software making final stack with stars definitely better. DSS completely disappoints when stacking photos with stars and comet orientation simultaneously. I’ve tested a whole range of configuration options available in DSS and the result was always the same – crap in the final picture.

What to do? How much I was thinking about how to bite this topic. Yes, I know, PixInside will say purists, but I don’t have time to learn another program just to process comets and simply saying, I just don’t want to.

I did not give up the topic. While testing many options available in DSS for stacking, I found that, with a specific DSS options setting, you could get a stack that contains small amounts of star trails but the comet stack was very nice of quality. Going forward I was able to get two stacks with comet of different colors, almost without stars in the background of the comet. With all those of photos with comets and stars made with APP, I could already play with masks in Gimp and put together three different photos into one, which has point stars and the comet as it should be.

Huh! it gave me a hard time processing this comet, like hardly any other subject in the astrophotography. My various struggles with the equipment for this hobby, did not cause me as much trouble as this comet. Even doing modifications of my NEQ6Pro assembly from gears to belts, it was like a nice walk for a beer.

Once again, I greet my colleagues Maciej Pawłowski and Marek Szymoński, who virtually accompanied me at that time and also photographed the sky.

I’ve took photos of the comet for the first time in my life. I admit that stacking and processing the comet is quite a demanding topic, I’m testing different processing options present. Well, it was easier for me to make this timelaps than a good stack, which I still have to work on.
