First CaK results

[GreatAttractor]

I'm learning how to use my newly acquired Lunt CaK module (straight-through, B600). Unfortunately there was literally nothing on the Sun at the time of capture, but the image quality seems promising (all from 90/660 mm achro, PGR Chameleon 3 mono/ICX445, AviStack 2, ImPPG):

Very nice images. I’ve always been intrigued by CaK.

Welcome to the darkside,       if you bought the lunt CaK b600 second hand,  take the erf's on the nose out to examine them.    They become totally degraded and rusted after just 2 years.

 

Lunt will  ship you a  new one if they are degraded.     Secondly if you are usning the aries d-erf you totally do not want the lunt erf on the nose or its gonna kill transmission.

 

looking forward to the future and your rc8 timelapse!

It's new, I had a look and the mini-ERFs look all nice and shiny for now. Good to know about possible replacement, thank you. I'll keep it in mind about usage with Aries ERF.
