February Moon, March Sun

 Last night (28 Feb) the Sightron infini D50 f/10.8 refractor was used to photograph the 12.4-day moon.  There were some thin cloud bands passing, but there was enough time to catch a clear shot.  The camera used on the moon was the Olympus E-M5iii.

This morning (01 Mar), the D50 was used with a ZWO ASI294MC-Pro camera to photograph the sun.  In addition to a front-mounted Baader solar filter,  ND-0.9 and UV-IR-cut filters were also used.  

Both of these shots were meant to test a new mounting arrangement for the D50 refractor.  This scope ships with a 4-inch flush-mounted  Vixen dovetail that works fine with the light-weight stock diagonal and eyepieces.  However, when heavier accessories are attached, such as a camera or large eyepiece, balance becomes tricky because there is not enough forward movement available. The new arrangement consists of two More Blue 60-mm tube rings (from Astro Hutech)  and PrimaLuceLab dual-sided Vixen-Arca-Swiss dovetails.


 

Sunspots are visible again after a stretch of several spotless days.
