Widefield Narrow Band with M4/3 Lens - Possible ?

[wornish]

I would like to do a wide field narrow band shot using my ASI1600MM and ASI EFW.

For normal photography I use an Olympus Micro Four Thirds DSLR camera and a series of M4/3 lenses. Is it possible to use the Olympus M4/3 40-150mm F2.8 lens with the ASI filter wheel and ASI camera. 

I am guessing the back focus is too short so it can't possibly work? 

Anyone tried this and if so how did you make it work?

That probably won't work unless total optical path is very short.

You need 19.25 mm of flange distance for M4/3 lens system.

ASI1600 has 6.5mm between top of the housing and sensor - so filter wheel really can't add more than 12.5mm and I doubt it is that short. We did not even consider lens mount which also needs to be added.

Maybe you could do it, but without filter wheel and only if you find really thing lens mount that accepts 1.25" filters.

Alternative is to use some other lens type mount and get second hand fast lens just for this camera?

Thanks you have confirmed what I thought.
