From Cepheus to Ursa Major

[Spongey]

This was a two panel commissioning mosaic for the widefield rig I've been setting up while my scope is out for repair, showcasing the vast array of dust across the northern celestial pole. With galaxy season in full swing and a massive FoV like this what else was I supposed to image?

The rig is based around the Sigma Art 40mm and QHY 268M, with images taken at f/2.8.

Total exposure time of 27 hours taken across the clear spell we had at the end of March.

A solved version can be seen below, showing the extent of this field.

Cheers

Definitely one to click on and zoom in!!

Very well put together 

Plenty of Integrated Flux Nebula to see.

Amazing stuff Rob...   so many objects to look at so worth zooming in to take a look.  Any chance you can post an annotated version?

Thanks Dave,

Unfortunately I'm struggling to get an accurate platesolve on the image, I think because it's such a wide field. Even the Astrometry.net solver drops off in accuracy significantly once you move away from the centre...

Any advice would be most welcome!

Wowsers, There’s a lot going on in that!! 🤩

Wow, super image. panning around the zoom version is amazing 👍

That's truly awesome!  Thanks for posting this great image. It may take me a while to get an accurate count for the stars.

Managed to get a half decent solve after generating a reference starfield and using the ManualImageSolver script! Annotated version included into the OP

Fantastic mosaic @Spongey a treat to look over at full size.
