Today was the first chance I have had to test out the latest addition to the family, a SW 200P.
Having spent the last few days stripping it down and rebuilding it I was eager to get out and give it a good test.
After it spend the afternoon on a DIY dob base doing some white light solar imaging this evening I mounted it in the observatory whilst I make a few alterations to the dob mount.

Nice !!! If you look closely at your image, you'll notice a red fringe on the bottom of the rings and a blue fringe at the top. You can use a Pierro Astro or ZWO atmospheric dispersion corrector (ADC) in the imaging chain  to help eliminate this at your low elevation angles. While not perfect, you can also use the RGB Align function in Registax to do this with your existing data.

Some nice detail showing there, +1 for the advice above as well. you data has probably got a little more to give potentially.

Thanks for the replies.
I had another look and attempted to reprocess the image, let me know what you think.
Thanks for the advise aswell, an ADC may well be on the list ready for next year.

Thanks again

Awesome.  The color has definitely improved.

 I went from the first image (2016, 30deg)to the second image (2017, 29deg) with a PA-ADC, though I've also gotten better at my planetary imaging techniques ( see Polar Hexagon post)

Very nice.
Out of interest apart from the ADC what other equipment was used for this shot?
