Today I tried to image sunspot 1422 and 1423 in whitelight. Unfortunately seeing was that bad that I couldn't go to 5x barlow, so I had to stay with 2,5x. But even this gave nice results. The image was made with an ED110 with DMK21(618) and powermate 2.5x in combination with a herschelprism with ND and solar continuum filter.

Hi Andre...
Nice set of images! I like the contrast...it shows the faculae nicely and the spots are nice and sharrp.

Re: Sunspots 1422 and 1423 in whitelight
Thanks for your nice remarks. The great halpha images here have triggered me to start thinking about building my own h-alpha telescope this year. Currently I'm thinking about a skywatcher 100/1000 refractor with a 110mm baader d-erf and pst etalon... Would this be a good combi? Is there much to gain by going even bigger (120mm) or is the gain then not so much? I will be probably posting much more questions in the modding forum this year...

I plan on making a 100mm f10 PST scope this year, I think you'll be onto a winner
