Milky way arch panorama from Cornwall

[AstroNebulee]

My first ever try at a milky-way arch pano. Needs loads more practice with stitching software as its looking awful with the banding and been a complete ball-ache. Taken on 25-5-23 over Delabole slate quarry in Cornwall. Using Canon 600D samyang 14mm f2.8 

10 panels of 10 images 13 secs at 6400iso. Dark calibration frames added. 

Stitched in Microsoft ICE and processed in Photoshop cs4.
I tried photomerge in photoshop but it didnt stitch with the end panels and gave the core part of the milky-way a tighter curve than is in real life. I did make sure each image overlapped nicely enough.
Need more trials to get it correct but I've been trying for days, so having a break now. Took some milky-way core images also so will process them.

I did manage to image the milky-way over 5 nights (not consecutively) during this good weather, no moon and the last throws of astro darkness.

Really well done - that’s a super impressive first pano, with loads of breathing space either side.

I also struggle with banding in the Samyang 14mm, which I think is a result of its very strong vignette. In theory I think a flat frame would deal with it, but who can be bothered to do that in the field?! So I’ve found that either making the overlap mega (75%-80%) or shooting in landscape orientation and doing more rows (again with plenty of overlap) really helps. I think setting a lens profile in Lightroom for the Samyang 14 would also help but (a) you need LR and (b) you need to know how to set it (which I don’t!). 😊

Thank you Paul, I really appreciate your kind words and advice. Yes I agree I've never taken flats with my dslr in the field either haha. I can't find time enough to get everything I need ina session I keep seeing more each time. 

I think my overlap on this pano was around 50% so not enough as I thought. 

Saying about a landscape panorama I have taken one earlier in the week when I shot this so will give that a go too. 

Flowing advice from Mary McIntyre she uses LR to apply corrective lens distortion on her images. So as you say I can't afford LR so I'm trying Raw Therapee and I see you can load up lens profiles for all different lenses and the samyang 14mm f2.8 is on there. When I try to do a photomerge in ps for the stitch it seems as though the canvas isn't big enough. Probably the overlap issue.

Thank you again for your help Paul. Keep up the great work on your vlogs 👍
