What's the actual size of your 2" filters in "mm" with and without frame/ring? What step down adapter is suggested from a 52 mm to "-- mm"?

Do all Baader narrowband filter both UV and IR as well? I am thinking of using them with a Full Spectrum DSLR. Thanks.

I have a non-modified Pentax K-1 DSLR camera. At the end of my t-ring is a 2" nose that accepts 2" threaded filters. Can I use this successfully for narrowband/Ha imaging on an unmodified Pentax K-1 DSLR camera with good results? I'm not expecting results as good as on a modified camera, but on an unmodified one is there at least some improvement when using this Ha filter and if so, how much? Please help. Thank you.

Are these filters compatible with the older, CCD-series filters? Is focus in the same place? I own some of the older filters and am wondering if I can use them together without a need to refocus.

I would like to install your 2" H-alpha 7 nm filter in an Astromechanics lens adapter/controller. However, the threads are located at the back of the adapter, and this means that the filter would thread in with the threads on the lens side, and the filter body facing the camera. I think that this is backwards from the way that the filter would be mounted in a typical filter wheel. I think that the orientation should be immaterial, but is that true? Thank you.

Can a H-alpha 7nm CCD Narrowband-Filter be used for viewing in conjunction with the Baader Solar Filter?
Question by: Greg Russell on Dec 11, 2017 2:58:00 PM | 1 Answer(s)
You state that this filter can be used down to f/2.8. Since I already have one of these filters I wonder if it will be possible to use it with a RASA 8" f/2 that I just bought? What problem may occur and do I really need the ultrafast filter?

Can you suggest a clear parfocal filter that can help reaching focus with the 7nm 2" version?
