Hello there:

 

I image with a full spectrum modded DSLR for which I use a Clip on UV/IR cut filter and also have a CLS-CCD. I now have a SW Evostar 80ED with the SW .85X FFFR.

 

My question is what are my options to add 2" LP and Ha filters.

 

I think the CLS-CCD is too strong and I do not want to keep buying Clip in/on filters as my plan is to upgrade to dedicaded astro cooled camera by next year.

 

Thank you in advance for your help.

Get an M56 to 2in barrel adapter ... something like this https://www.firstlig...-reducers.html   2in filters will then thread onto the barrel end of the adapter.

 

Yes, you are giving up a threaded connection so you will have to watch for any sag in the 2in barrel connection, but at least you will be able to use 2in filters.

 

Edit: Just noticed that FLO also has a threaded adapter for just the 2in filters. This would let you continue to have an all threaded connection. https://www.firstlig...flatteners.html

Mark thank you for the info. I ordered the M56 to 2in from Flo before I saw your replay. I might order the other ring too.
