I wasn't expecting to see the Sun for at least a week according to the weather forecast yesterday, so it was a pleasant surprise this morning when after a conference call in my 'man cave' I emerged to see a beautiful blue sky. I knew it wouldn't last, so set up quickly and ran a couple of quick FD mosaics with the DS Lunt 60 fitted with a Coronado BF15 and Lunt B1200 and a FD mosaic in Ca II K.
Here are the results.
Ca II K first (Lunt 1800 module, Omega and Baader K-Line)

...and the Ha FDs. (OOPS Forgot to flip the images!)
Lunt/Coronado BF in colour and mono

and the Lunt/Lunt BF
This was imaged and processed in exactly the same way as with the Coronado BF, EXCEPT that the image is much less bright with the Lunt BF, so I had to increase the gain to bring it to an acceptable brightness.
I'd say the Lunt BF image is less clear/defined than that taken with the Coronado BF and has lower contrast.

Given more time I could have tried to optimise for both, but the clouds were rolling in so that was that.....
Thanks for looking.
Stu.

Very nice Stu, the Lunt blocker seems quite washed out in comparison to the Coronado. Hope you get to test again soon

Re: Sun in Ha and CaK 18th Feb '21
Many thanks, everyone.
My focus now is to tweak the tuning and exposure settings using the BF15 and re-learn how to get the best from the DS Lunt 60. Roll on better weather.

Re: Sun in Ha and CaK 18th Feb '21
Great images Stuart, always nice to have some surprise sunshine I do prefer the Coronado blocking filter though
