Explore Scientific FirstLight 127mm Doublet Refractor for solar photography

Description

Decided to purchase an Explore Scientific FirstLight 127mm doublet achromatic refractor to use as a solar telescope for detailed chromosphere solar photography. There is a Daystar Quark Chromosphere and ASI174mm monochrome camera attached.

The Explore Scientific 50mm finder scope (with solar mylar protection) could cause small errors in balancing and tracking. I may end up using the cheap red dot finder, with Solar mylar securely wrapped on the front. Daystar documentation states the Quarks works best using refractors of F/4 - F/8.

The ES FirstLight doublet refractor has a focal ratio of, F/9.4 and with the Daystar Quarks 4.2x telecentric internal Barlow, which should push the focal ratio to a little over F/39. Hopefully, this will work out to image capture great chromosphere surface details.

I do have a 2.5x Televue Powermate to evaluate as well. Hopefully, this weekend I'll test out if the skies finally clear.
