C/2019 Y4 (ATLAS) – TimeLaps

Comet with a near-parabolic orbit, which 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’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.

A swarm of satellites

in Iceland astrophotographer has a difficult situation. The aurora itself is beautiful but for locals who would like to watch deep sky objects (DS) it must be a big of stress. Additionaly astrophotographer have a swarm of satellites ovehead. The film shows the swarm of satelites before Mr Musk intensified rocket launches with Starlinks. I am afraid to think what will happen when all starlinks and other planned satellites will be placed in a low orbit.

Leo Triplet

Also known as the M66 Group is a small group of galaxies about 35 million light-years away[5] in the constellation Leo. This galaxy group consists of the spiral galaxies M65, M66, and NGC 3628.

The first test photo taken on the new Orion Optics CT-10 telescope on a modified assembly (gears replaced with belts + new bearings) NEQ6Pro. I did not collimate the telescope, I used it as it came from the supplier. You can see with the stars that I need to improve collimation. Flats didn’t work out as they should, but I somehow corrected it in the GIMP. The coma corrector I used with the previous Newton 1000/200 [mm] did not like this telescope model too much. The IDAS LPS-D2 48mm LP filter, which I used for the first time, passed the 5+ exam. This set will need to be further improved.

Milky Way – mosaic of three frames

This is mosaic of three frames, manually set. I had four frames done but the third in the queue was bad quality and went to trash. This is my first mosaic. It is a pity that I could not set the frame, which is why the picture is not complete. In overall, the final photo is not so bad. I remember getting a bit tired of setting these frames, it is not as easy to do as it may seem. Certainly, the ideal support for such a “work” will be a computer with the solid software that will align the frames each other as they should be with some overlap.

Photos taken at 02 Jun 2019 on Tenerife, exactly in the place next to “God’s finger”. Great expedition with PTMA.

As usual, I couldn’t decide which picture is better. Version with the actual number of stars or reduced. Personally, I like both and I also post both. Certainly the “without” stars version is not suitable for viewing at high magnifications, till some reasonable level you can. It is better to magnify the “with stars” version.
