What is the thickness of the filter?

It's designed for 40nm FWHM~
You do mean it's spectal bandwidth. I asked the thickness of the glass itself. 6mm, 10mm or 12mm ?

My friend replied me. It's 4.5mm

Re: My New BinChannel ERF

40 nm FWHM in both Ca K and Ha is amazing. What far goes the blockage in IR ? 1000 nm ? 1200 nm ? Any idea of the optical quality (P-V or rms wavefront) ? 2 bands,393nm and 656nm,40nm FWHM for each. Maybe 1000 nm or 1050nm ,because I did not get any more information above 1050nm P-V I have not any ...

20181030 CaH Prominences

I tried with my 60mm f/6 EDAPO this morning. With a 2X barlow,it was suitable with the QHY5-III 174M in CaH-Quark.

It's really surprised me that there's some small proms.

Re: My New BinChannel ERF

The diameter of this ERF is 8.5 inch. It may get f/11 with my C925HD,and with a 2x barlow to use the Combo Quark.
Maybe I need to get a focal reducer with them.

Re: My New BinChannel ERF

Looks good ! Any idea of the optical quality ? Any transmission curve available ? My friend told me that they choose 5 points for testing. The report shows that the coating is well-distributed.The Ha channel is about 87~90% transmission and the Ca-K/H channel about 84~85%. They made Ha-ERF for the ...

My New BinChannel ERF

I booked a binchannel ERF from an optical engineer friend about 4 months ago. And I got my new ERF's picture this morning.It's really beautiful. The ERF was designed by 80% and above transmission near 393nm and 656nm. BinChannelERF.jpg I'm preparing to use it with a C925HD and Quark(CaH and Ha) and ...

Re: Quiet Disc Today | HA | Oct 28th

And I'm interesting in which 1.5x Barlow do you use? Hello! I used a standard GSO 1.25" 2x barlow and unscrewed the lens off the barrel and screwed that lens directly onto the nose of the camera. I took two images and scaled them and it was approximately 50% the size, so I knew I was in the 1.5x ba...
