Andromeda-Galaxy M31 with 80x 1 minute exposures using a telezoom lens on an equatorial mount.

18 Nov 2020

80 Lights with 1 Minute exposure time

205 mm Telezoom objective f/5.6

Canon EOS 700D unmodified piggybacked on my

equatorial-mounted 80/600 telescope.

Processed with Siril and Affinity Photo

I always have a hard time to meet the correct focus,

so decided to take images through my telescope next time.

18 Jun 2021 - NGC700 (North America Nebula)

15 Lights with 300s exposure time

Canon EOS 700Da with 300mm Lens

using Optolong L-Extreme filter.

Processed and stacked with Affinity Photo.

This is the first time I used KStars/Ekos. The guiding still does not work perfectly, because Ekos is more sensitive to mount backlashes. During last month I already reduced the backlash of my mount, perhaps still not good enough?!

The is a small banding visible, but not horizontal or vertical so it does not have to do with the typical banding of a DSLR camera.

It is still very difficult to find the focus of a camera lens, at least it is much easier to meet the focus when using a telescope, however this object requires a much smaller focus length to fit into the field of view of the camera.

15 Lights with 60s exposure time

Canon EOS 700Da with 80/600 Telescope

using Baader Moon and Skyglow filter.

Processed and stacked with Affinity Photo.

Captured using KStars/Ekos. I build my own telescope pier in my backyard. Using Ekos I improved my polar alignment, which is now in the range of 20“. This significantly improved my guiding.

17 Jun 2021 - NGC6960 Veil Nebula

24 Lights with 300s exposure time

Canon EOS 700Da with 80/600 Telescope

using Optolong L-Extreme filter, no darks.

Processed and stacked with Affinity Photo.

Captured using KStars/Ekos. I’m still having trouble with the Ekos Capture & Solve feature. It works fine with my guiding camera, but always fails with my Canon. For this reason I cannot frame my objects as I want (or it would take too much time). Need to find a solution for this. Finding the focus with the L-Extreme filter is still another problem.

25 + 29 Sep 2021 - Sh2-157 Lobster Claw Nebula

75 lights with 240s exposure time (5 hours) + 77 lights with 300s exposure time (6hours 25min)

Canon EOS 700Da with 80/600 telescope

using Optolong L-Extreme filter, no darks.

Processed and stacked with Affinity Photo.

Captured using N.I.N.A. Mixed two nights of exposures.

09 Oct 2021 - M31 Andromeda Galaxy

180 lights with 180s exposure time using Baader Neodymium filter with Canon EOS 700Da and 80/600 telescope.

Processed and stacked with Siril + Affinity Photo.

Captured using N.I.N.A.

15 Oct 2021 - IC 1805 Hart nebula

This is my first mosaic of 90 lights with 300s exposure time using the Optolong L-Extreme filter with Canon EOS 700Da and 80/600 telescope.

Creating mosaics seems to be sometimes problematic as I tried Deep Sky Tracker to stack the mosaic but did not get good results, so finally I ended up processing the two parts separately and merged them together in Affinity Photo.

Processed and stacked with Affinity Photo.

Captured using N.I.N.A.

24 Oct 2021 - IC 1842 Soul nebula

112 lights a 180s + 65 lights a 300s using L-Extreme filter with Canon EOS 700Da and 80/600 telescope.

The blue parts start to come out, but this is still not enough light to get a good result for the blue.

Processed and stacked with Affinity Photo.

Captured using N.I.N.A.

The Orion nebula M42 captured with the Omegon veTEC 571c

02 Dec 2021 - Orion Nebula

About 5 hours of total exposure time (10s, 60s, 300s)

using Baader Neodymium filter with Omegon veTEC 571C and 80/600 telescope.

Stacked with Siril, processed and combined with Affinity Photo. Captured using N.I.N.A.

10 Dec 2021 - Plejades (M45)

30x10min exposures using Baader Neodymium filter with Oregon veTEC 571C and 80/600 telescope.

Captured during moon in first quarter, after 6 hours clouds came in.

Stacked and color calibrated with Siril, processed with Affinity Photo. Captured using N.I.N.A.

13 Jan 2022 + 23 Feb 2022 - Rosette nebula

50x5min exposures using L-Extreme filter with Oregon veTEC 571C and 80/600 telescope and 1h of RGB data without filter.

Processed with PixInsight. Captured using N.I.N.A.

06 Jan 2022 - Horsehead nebula

16x10min exposures using Baader Moon & Skyglow filter with Oregon veTEC 571C and 80/600 telescope.

Stacked and color calibrated with Siril, processed with Affinity Photo. Captured using N.I.N.A.

02 Mar 2022 - Cone nebula

3 nights exposures with Oregon veTEC 571C and 80/600 telescope.

Processed with PixInsight. Captured using N.I.N.A.

09 Mar 2022 - M81 & M82

About 10 hours exposures with Oregon veTEC 571C and 80/600 telescope.

Processed with PixInsight. Captured using N.I.N.A.

The faint structure in the background is the galactic cirrus. I captured this target over 5 nights and collected more than 30 hours of data, however due to

guiding issues and airplane trails only 10 hours could be used for stacking.
