For adapting any cell mounted Baader 2 inch Filter onto a camera lens with 52mm front filter thread you will need:

Based on the SP54 thread, we offer many more adapters for various camera threads, our so-called Hyperion DT-rings. https://www.baader-planetarium.com/en/catalogsearch/result/?q=sp54
Both thread sizes come with our proprietary pitch - which is not the same for the female and male threads.
This is our own proprietary "emergency solution" for uniting a world were manufacturers all over the world copy from each other - to the point that there are almost a dozen different pitches in use for male and female threads. Traditionally US-companies used to do a UNF-based pitch and the rest of the world went for metric threads - but these do vary from 0.5 to 0.75.
For this reason it does not make sense to publish our non standard pitch because our pitch is made to cope with all existing metric and US-pitch standards - and as said - our solution has evolved from sheer necessity. It is a mixture of a queer pitch and under-/over-dimensioning . We will not want to declare this as a standard and get bashed up for it. It works for us and is a result of 20 years adaptation to fit our filters onto all crazy threads we have seen. And inspite of this - every now and then there comes another "dragonboat-eyepiece" were even our filters may not fit...
1. Are these LRGB filters suitable, do the LRGB filters need to be matched to the F/2 as well similar to the H-alpha etc.?
2. If they are suitable are they parafocal with the high speed F2 filters? So I can focus using the L filter and swap to the H-alpha ?
2. This depends on the thickness of the filters. If you are using LRGB and narrow band filters of the same size,
they have the same thickness, therefore they are parafocal.
I bought some an SBIG filter wheel FW5-8300 that came with 36 mm unmounted LRGB filters in 2015 *used*. The original owner claimed that the filters are Baader filters. No filter cases came with my purchase.
Recently, I examined the filters and found that
the L filter had an /\ mark on the edge which is what I believe Baader filters should have. But the RGB filters do not. Question: Do the Baader filters always have had /\ marks on them? If not is there a way to check whether they are Baaders?
