I have a lumicron H-Beta filter 1.25" I would like to trade for a UHC
The threads got messed up on the original cell and it has been put in a new one ( Which I have used for over 3 years like this without any problem) There is a very very small nick in the edge of the lens.
Now for the good part. I have compared this filter with two other H-beta filters, same brand, in side by side compairsons and it beat out both of them.
This is a good performer and I will gladly take it back if not satisfied for any reason.
Now that I have a "large" dob I can see the horsehead without the filter on those good,clear,dark nights. also my FOV is now too small to enjoy the california nebula with this filter so it is not getting much use. I feel that a UHC would suit me better.
A 2 inch filter would be nice but I will consider 1.25" also.
Get in touch with me to work out details if interested.
