M81 Spiral Galaxy

M81 spiral galaxy image of last night from my balcony

 

A 5 hour constant struggle with guiding, re-centering and guidescope flexure with the C9.25 Edge HD, and many more work in post to clean it up as much as I could using 3 softwares (Pixinsight - Photoshop - Lightroom)

 

Luminance data using the Hutech LPS 2" filter / ASI1600MM-C (Mono)

320 x 1 minutes subs (limited exposure due to flexure, poor seeing and bad guiding)

No flats, no darks, but the constant flexure helped with dithering the data :D

0.7x Edge reducer

Done
