Comet C/2021 A1 (Leonard) using APP 1.083 Beta2

On the morning of December 8th, 2021 I was able to take some pictures of Comet C/2021 A1 (Leonard) which is located in constellation serpens. 

Setting : Nikon D7500 and TLAPO80/480 f/6; 30x30s ISO1600, darks, bias, flats and darkflats. Stacking with APP 1.083 Beta1 (comet option) and final editing using CS4 and DeNoise AI.

MAI 75 SSTV Expedition 66 December 1 Event - Results

Today the ISS was submitting images to Earth as part of the MAI75 SSTV Expedition 66 event. I used the websdr from Nürnberg (http://nbgsdr.ddns.net/) and MMSSTV software. The results were rather poor. I was able to receive 5 pictures but not one was really good.

Darth Vader's Galaxy NGC936

As a Star Wars fan, the object NGC 936 is realy cool. The galaxy looks like a Star Wars Empire (advanced) TIE fighter and was named Darth Vader's Galaxy. It's located in constellation Cetus and is about 60 million lightyears away from Earth. It forms a pair with NGC941. When comparing the field of view with SIMBAD we will find more then 160 galaxies aswell as Quasar 4C 01.11 with a redshift z=2.038.

Setting : Nikon D7500, TAL200K f/8.5, ZWO Mini Guidescope 30, guide camera ASI224MC.
Image : ISO400, Lights 12x90s; 4x300s, Darks, Flats, Bias and Dark Flats.

Software : N.I.N.A, PHD2, APP, CS4, DeNoise AI.

My Current Astrophotography Set Up

 

This flowchart is a visual of my current astrophotography set up. Starting from my mount untill processing of the astropictures. Still some learning to be done eg. the use of platesolving. 

Finding COM-ports in Windows 10

Windows10 environment: type "configuration" in search field (right of Windows Start). In the Click on devices and this will show the ports. If ports are not shown, click on view and enable "hidden devices".
