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

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.

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

80/600 Telescope, unguided

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. 

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.   

North america nebula NGC7000

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. 

M13 Globular Star Cluster in Hercules

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.  

NGC 6960 Veil nebula

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. 

NGC 6888 - the Crescent nebula

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, 

Veil Nebula

08 Aug 2021 - Veil Nebula


Only 8 lights with 360s exposure time

Canon EOS 700Da with 300mm lens

using Optolong L-Extreme filter, no darks. 

Processed and stacked with Affinity Photo.

Captured using KStars/Ekos.  At lot of things went wrong during this night: 

Ekos autofocus feature did not work with my lens., 

Plate solving failed and Auto guiding worked very bad for unknown reasons, maybe due to seeing conditions and a misbalanced mount. I dithered for every image. Planned were 40 subframes, but due to a lot of time spent on trouble shooting only 8 subframes were available after 4 hours. 

03 Sep 2021 - IC 1396 Elephant trunk nebula


20 lights with 420s exposure time

Canon EOS 700Da with 250mm lens

using Optolong L-Extreme filter, no darks. 

Processed and stacked with Affinity Photo.

Captured using KStars/Ekos.  Some problems with guiding this night, planned were 40 lights but during the 6 hours night only 20 lights could be captured.  However, I tried this target several nights and always a lot of things just went wrong. Now it is enough for me, I will give this another trial next year. :-)

04 Sep 2021 - M31 Andromeda galaxy


40 lights with 300s exposure time

Canon EOS 700Da with 80/600 telescope

using Baader Neodymium filter, no darks. 

Processed and stacked with Affinity Photo.

Captured using KStars/Ekos.  Guiding/Dithering worked perfectly using the GPG guiding. I used a Bathinov mask on Vega for focusing and I think such a mask is worth the little money it costs.
