That's really good.
It's amazing what you can see on the sun, even in normal 'white' light.
I use an 11" Celestron SCT (CPC 1100) on an equatorial wedge, with an 80mm refractor as a guidescope. They are housed in a 2.2m Pulsar observatory. I use a ZWO ASI1600MC for imaging.

Hi Aratus thanks for the reply,it was quite stable with a bit less wind.I could use my mono camera and it was quite good at 2x Barlow.I did try the colour camera but did not show as much detail.

There is no actual colour on the sun anyway, so a monochrome camera is no handicap. I believe the finest solar photos have been done on a monochrome camera, so you are on the right track by using one. People often add a bit of orange or yellow afterwards to give the image a bit of interest.

I think it is one of these targets where the more photos you take, the better the chance of getting a good one.

I'd like a camera where all pixels are sensitive to hydrogen alpha light ONLY. The Bayer matrix is a pain in the <expletive> for solar photography. For "white light" photos I just use the green channel and discard the red and blue.
How can I be one with the universe when we don't know what 96% of it is.
