A lot of the hi-res solar images that I see here are stunning but at 60mm aperture I will never get that level of detail due to excessive oversampling. With the equipment below and camera binning at 1x1 resolution would be 0.48”/pixel and way too noisy.
Today I mucked around with binning at 2x2 with an ASI174mm and a 5x Powermate and came up with the image below of AR13006 at 0.97”/Pixel. This is a more sensible level plus it allowed me to reduce the exposure time and improve FPS. The image is comprised of 200 out of 2,000 frames. I will keep plugging away and see how it goes but today I feel I was lucky with the seeing.

Have you done a side by side comparison - the 174, 1x1 binning and 2.5x barlow vs the 174, 2x2 binning and the 5x barlow? Would be interesting to see how the results and exposure settings etc compare.
