Solar Mosaic AR 2665 12th July 2017

[SlimPaling]

This is my 3rd attempt of producing a mosaic image of the Sun .... I am new to this and trying to improve my technique. I am not 100% happy with my results but at least I am getting better at blending the mosaic panels so that he joins are not too noticeable !

I used my APM refractor with Herchel wedge + 3.9 worth of ND filters + a polarising filter ... and the images taken with my DMK mono CCD camera. I made 18 sets of video files each one processed in Registax 6 and the end results assembled on Photoshop CC

I am a bit concerned that my image of AR 2665 looks quite different to the "official image" on the SOHO web site.

I am also concerned that my images seem to lack clarity and definition of the sunspot details compared to all others that I have seen posted. My APM refractor is a pretty decent piece of kit .... so do I need to get a better quality camera??? Or do I need to move to a place where the sky is cleaner?

Any helpful advice on how to improve my efforts would be muchly appreciated :-)

Looks really good - on looking very closely, I can see a little error on the limb at about 8 ocllock. I would use the patch tool in Photoshop to fix that if you have that. You can replace the selected area with an adjacent area so shading and texture can be maintained.

great mosaic, you have done well to stitch them at all with it being near impossible in WL, Ive only ever managed to stitch one disc and that had quite a few more ARS on it which made it easyer. well done. charl.

Good disk. As Charl said, WL mosaics are tricky at best of times. You're on a loosing streak straight away trying to compete with SOHO! Try comparing with other images on the forum here, a much more realistic benchmark.

yea soho is too low a mark to aim at our images are much better  charl. I was joking abit wink.

As Charl said, WL mosaics are blighters so well done.

A fine looking image.

Well done. I have generally find WL mosaics only work when there are several notable ARs scattered over the disk. I have given up on them when the sun turned this quiet
