17th October WL granulation

Post by robert » Wed Oct 17, 2018 1:34 pm

Today was moderately clear weather, high pressure but showers and a gusty wind. The sun only getting to just over 20 degrees altitude. However I have been noticing that the SSM shows quite good readings despite all this at around 1 arcsec. So I tried the SW200 (f1000mm) Newtonian with ND3.8, Baader continuum, UV/IR cut and two different lenses, Celestron x3 and Televue x5.

Hi Robert...

Both images look great considering the low elevation of the sun :bow

The 3x is very sharp, but the 5x still looks very good. A 4x might have delivered a bit more resolution but still excellent results.

Very nice images, Robert. I prefer the second, but both are good.
