"In any case it is better significantly than K-line."
1) Valery why did you say that ?
I guess Montana and myself are not seeing a great difference from Baader K-Line
2) so your guess is that FWHM some where in 4A-6A area with this filter?(caH)

1. Bacause I see much finer details in 5A Ca H line than at images with K-line 80A (!!!) filter.
The image made by Walter with 6" refractor and 5A Ca H is FUUUUUULL of fine details never imaged with K-line filter.
2. I guess it is about 4A FWHM. The problems are:
a) Poor seeing.
b) Equipment.
c) small scale

Hi Mark
thank you very much. We have to extend that discussion and it will take time. Another 12 days gone without having had even the chance to capture the disk very heavy dark side syndroms, I'm suffering

Re: well here it is sun omega bob caH
VALERY Would stacking another caH filter
3of them would make band more narrow
or does law of diminishing return
set in ?

Re: well here it is sun omega bob caH
I don't think this is a good idea - to stack three Omega filters. Too expensive! Even two filters are too expensive cause it ishighfnum wrote:VALERY Would stacking another caH filter

possible to buy CaK PST or Lunt B600 for comparable or even less money and have CaK with narrow enough bandpass.

Re: well here it is sun omega bob caH
well
I took a few tips from Valery to heart
1) CAh with extra element filter that bob sent me
2) increased FL now F30 for more parallel beam
BUT seeing conditions were horrible - sun looked like I was at bottom of a pool
high winds - i was forced to use my 60mm unitron which is pushing that little baby
none the less if you look close thru the mess
it looks like I have potential for a good image - surface looks more caked
I feel silly posting such a mush image but that is what I have now

Hi John
bravo you went out despite the horrible seeing conditions. The result however is not convincing me

Re: well here it is sun omega bob caH
I have a question about daystar caH
this is mostly geared towards Walter
but anyone may chime in
why was 5.0A chosen instead of 2.0-3.0A like thier caK??

First thing what you need to improve is the camera.

as simple as that, it was the only filter available. Soon I will receive Bobs CaH and can double stack
