Looking for advice with selection of dual narrowband Ha/OIII filters for fast (F2) systems - Forums

Topic starter

I'm planning a new setup with a Celestron C14EdgeHD plus Hyperstar. I want a fast system for Ha/OIII imaging at a remote dark site. I'm thinking of a colour camera with a dual-band Ha/OIII suitable for fast systems (as a filterwheel would obstruct too much light, and I want to avoid manually changing from Ha to OIII filters at a remote site). Any experience/advice welcomed, especially with the ideal bandpass given the reducing transmission with very narrow bandpass, but also the desire to minimise the bandpass to avoid non-Ha/OIII light).

I use the regular speed version of the IDAS NBZ on my Hyperstar (v4 with 2600mc) and am happy with the results (I’m new, no posts with it uploaded yet). It claims it works to f2, and their high speed shifted one goes lower.

I’m not familiar with other manufacturers, but I believe a few others also provide high speed versions.

I have a Hyperstar on a C6 and use the Antlia ALP-T Highspeed. Its been great for me and got a lot of use out of it this past year. I got a friend who has the NBZ that I would love to borrow and do a comparison on.

For dark skies the NBZ UHS is a good choice for Hyperstar. No reflections and excellent QC. Each individual filter is tested with a spectrometer and is shipped with a test report.

You might check and see if Samara is still active here. She had great success putting a filter wheel on an Edge 11 scope with the Hyperstar IV. You've got a lot more real estate to work with. Unless you have totally ruled out that option.
