Sun in Ha and Ca II K, December 15th 2020

Post by Carbon60 »

Hi all,

A couple of quick FDs during a short period of blue sky this morning.

First up Ca II K with a Lunt B1800 module/Omega/Baader K-Line combo on an acA2440-75um with a 1.5x Barlow.

Ha using a SS front mounted etalon (Lunt 60) on a 72mm f6 with a Coronado BF15 blocking filter. Somewhat under sampled with the Basler acA1920-155um and 1.5x Barlow.
