North America Nebula in Ha - 4 Panel Mosaic

[The Lazy Astronomer]

Well, I wasn't quite prepared for 5(!) consecutive nights of clear skies there were in South East UK last week, so after I'd got around 6hrs on the Pelican nebula (which hopefully I will be able to process this week), I was hunting around for something else to shoot and decided to try a new technical challenge and attempt a mosaic.

Due to short nights, and as it was just a few days off being a full moon, l decided to stick with Ha only (plus, who doesn't like a lovely little mono Ha image, right?).

This is a 4 panel mosaic, 12 x 300s subs per panel (except panel 4, which due to a technical issue, has 1 sub fewer than the others). Stitched in MS ICE, processed with Startools. Binned the composite image x2 to help boost the SNR a bit as only 1 hour per panel wasn't really enough to get a clean looking image at full resolution. 

Anyway, here it is, presented in a slightly unusual portrait aspect.

Thoughts and comments welcome!

For only an hour per panel I think it looks very good! 👍
