Coma Cluster, ACO 1656
Using my usual deep sky gear, N 150/750, Baader MPCC Mark III, Canon 1100D mod, HEQ5 with the IDAS LPS D2 in place, I imaged the Coma Galaxy Cluster, ACO 1656. I acquired a relatively modest amount of expos, 9×4 minutes at ISO 3200, from the haystack in Dângău Mare.
Obviously, I used my photo planner to plan this job.

At 02:35UTC I imaged the giant and its moons with the fairly new N 250/1200, TS Optics ADC and ASI 224MC.
G, C, I, E and Jupiter
Markarian’s Chain
I already had two attempts at imaging Markarian’s Chain, see here and here. Now I let my gear to shoot 22×5 minutes at ISO 3200, using the N 150/750, Baader MPCC Mark III, Canon 1100D mod, HEQ5 with the clip in IDAS filter. Location: Dângău Mare, Cluj, Romania.

The Whale Galaxy
On 2019-03-30, from Dângău Mare, I imaged the Whale galaxy, a well known target. I used my N 150/750, Baader MPCC Mark III, Canon 1100D mod, HEQ5 setup, with the IDAS LPS D2 filter in place, and captured 26×4 minutes at ISO 3200. It was surprisingly easy to process the resulting images.

And the Whale’s “breath” is

As you probably know the technic, cross your eyes until the two pictures meet in the middle and try to look at that middle image. It will be a “sphere”.

Jupiter with E, I and G
Using my standard planetary setup, the 150/750 tube, an ADC and the ASI224MC, I imaged Jupiter. (tovább…)
Jupiter is very low on the ecliptic and very far fr
om opposition. This make the giant planet I was able to successfully image before (like this, in 2015, around Gemini-Cancer-Leo), a very difficult target for the beginning of this year’s season.
