Re: NEW direction in the solar narrowband imaging.

Has anyone considered trying an h-alpha etalon without the red filter and replacing the spacers to change the reflectivity and blocking filter with a calcium filter? If we had a complete spectrum prof ile of a pst etalon it maybe way cheap to have the spacers remade for a different airspace to chang...

Re: NEW direction in the solar narrowband imaging.

That spectrograph has a resolution no filter system will ever attain without a piezo electric atomic line filter.

Re: NEW direction in the solar narrowband imaging.

Valery, then order them. Dont know what to tell you.

88% transmission and hard coated, indestructable to moisture and pollen. Immune to thermal drift up to 150c. 27mm fully mounted.

Post your filter curve from a carey spectrometer with 1angstrom resolution.

Re: 393.4 bp0.1 - yes it does exist.

Great post joe, that is remarkable! It looks like the 854.2 is showing some brighter saturated flocculus than the CaH image. The 546.1 mercury line looks way awesome compared to them all. I wonder what this line looks like at 4000mm, that is worthy of a daystar custom order. examining that mercury i...

I am trying to help Apollo get the funds for the first prototypes, that is all i can do. I do not know any of the information you request other than it will be guaranteed to be greater than 85% transmission and less than 2 angstroms each filter. I can ask all the questions you want, but getting the ...

Using the cheapest extension mod, 52mm - 46mm step down plus a 52mm - 52mm male male adaption I can pretty much put this where ever I want no...

Valery: you personally buy and resell/return pst etalons to "find the best one" So you are hand picking and sorting through rejects yourself. You just didnt buy one thing something and get satisfied with how you feel about your system. Merlin is using omega optical filter, which has been known and r...

Tonight I removed the filters from the gold skybender and placed them in my 2" blue skybender, it just seems appropriate to make it blue :) I almost removed the second etalon from the eyepiece section and threaded it into a new twistlock 2" barrel This will keep the filters further away from focus, ...

Re: Return of the Double Stack - 21st June

I just noticed you are using a coronado blocking filter on the lunt system.

I had no idea they were compatible, do you notice a difference between the lunt blocking filter and the coronado blocker?

Re: 393.4 bp0.1 - yes it does exist.

Valeryy, i just asked your question about the 854.2 filter , you are looking at a cost of $3500 to prototype it for two 27mm filters and the process to make them currently has a low yield with low success rate. So they are pretty rare to make exactly where you want them and have to be sorted out ver...
