blocking filter
Hello Guys just a quick question for you experts out there. I have a 60mm H-alpha Telescope, B1200, Feather-Touch focuser and Pressure Tuner and was wondering is there anything stopping me from using a b1800 blocking filter on this telescope? Steve

Re: blocking filter
No reason at all other than it's more expensive. You'll be fine with the 1200 i'd think tbh tho...

Re: blocking filter
Steve,
The BF1200 is alreadylarger than the light cone could ever get in the 60mm Lunt so there would be no advantage to going to a larger one in that scope. In fact, the smaller blocking filters generally are more even with less abberations so you may actually loose some image quality by overbuying the BF.
