Astrophotography

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.

Orion nebula and running man 79x 20s exposures using 80/600 telescope, unguided.

79 Lights (from 180 taken) with 20s exposure time

Much easier to find the focus, however without auto guiding the exposure limitation is not satisfying.

Also the running man and a lot of details are not reddish. Would be nice to have a astro modified camera.

Horsehead nebula and flaming star nebula 43x180s guided.

05 Mar 2021 (Horse-head Nebula)

43 Lights with 180s exposure time

80/600 Telescope with Autoguiding

Canon EOS 700D astro-modified

using Astronomik CLS filter.

Processed with Siril and Affinity Photo.

Autoguiding works fine. But long exposures are not possible without the use of light pollution filters. Unfortunatly, I only have the Astronomik CLS which is not indented for being used with an astromodified camera (without IR blocking filter). The star colors are not perfect and the entire image could have a longer exposure 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.

17 Jun 2021 - M13

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.

29 Jul 2021 - NGC6888 Crescent Nebula

20 Lights with 400s 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. Focusing is still a nightmare. I’m having trouble creating darks with the same temperature and the nights are so short,

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.

06 - 08 Oct 2021 - M33 Triangulum Galaxy

220 lights with 180s exposure time (11 hours) using Baader Neodymium filter + 40 lights with 300s exposure time (3 hours) using Optolong L-Extreme filter (to capture the HII regions) with

Canon EOS 700Da and 80/600 telescope.

Processed and stacked with Siril + Affinity Photo.

Captured using N.I.N.A. Mixed 3 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.

25 Dec 2021 + 13 Jan 2022 - Rosette nebula

22x5min + 50x5min exposures using L-Extreme filter with Oregon veTEC 571C and 80/600 telescope.

Captured during moon in last quarter and near full moon.

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