Hi,
I got first solar imaging with AT60ED, Daystar Quark Chromosphere model (4.3 barlow), 1.25" 0.5x GSO Focal reducer, and ASI174MM. See image in below link

I see that the quark works best at F30+ whereas my setup is less than F30 (6x4.3 = 25.8). Would aperture reduction make the contrast better?
