The Nebulae of Auriga


My entry for the April Image of the Month Competition!


I am going through a spell of loving widefield imaging with a DSLR and tracker at the moment. I am loving capturing multiple targets within one frame!


This image has been captured on multiple nights throughout April.

Image acquisition


Lights - around 125 of 2-3min exposures @ ISO 640-800 

Bias - 166 


No darks, no flats - for my widefield images I am finding that darks and flats are not helping but in fact making the stacked image worse, so I have been leaving them out and getting better results.




Camera: Canon 70D (astromodified)

Telescope: Askar 180FMA 

Mount: iOptron Skyguider Pro

Filter: used both the Astronomik Ha 12nm Filter and the Skytech Triband Filter. I did try using a CLS-CCD but this didn't improve my image. My light pollution is overwhelms this filter (I live near an airport)


Stacked in DSS, and processed in Affinity Photo. Slightly cropped around the edges but nothing more than that. 


and that's it. No guiding, just a wireless intervalometer - keeping it light weight and simple. Perfect for a beginner like me!

Thanks! I'm gonna keep adding more frames to it once Auriga appears higher in the sky again after summer. I'm certainly not finished with this one yet.
