A nonad of Cepheus Sh2's - finally in SHO

[Adreneline]

Finally got a break in the weather sufficient to capture OIII and SII data to go with my existing Ha.

This is a two pane mosaic taken with the Samyang 135mm + ASI1600MM with Antlia 3nm filters.

Pre-processed in APP and post-processed in PI using all the Xterminators. Pure SHO combination with magenta removed and all but 5% of the green cast.

I think a third pane would be helpful to extend the f.o.v. just a little to the right of IC1396 - but maybe the same thing can be said for extending to the left! Where to stop.

Thanks for looking.

That´s a beautiful pano! I´m hoping to get back into astro photography myself and this is inspiring!

Thank you Peter. I know many prefer PI but when it comes to stitching panes together for a mosaic APP makes it so easy and providing you've removed background gradients (also very easy in APP) the seams are invisible.

Thanks again.

Thank you Martin. When it all goes to plan AP is a great and rewarding hobby and wide field images of large areas of nebulosity are always captivating.

Thanks again.

Thank you Olly.

I actually took a third Ha frame centred on IC1396 but so far I've not been able to get the OIII and SII. I feel IC1396 is a bit too close to the edge - but I guess you could say the same for Sh2-142. The mosaic dilemma - where to stop?!

Thank you Martin.

I prefer subtle to "in your face" 😆. I'm glad you like it.
