Nikon DSLR Ha clip-on filter

Hi, I was wondering if there is anything like what you can get for EOS cameras, where you can clip in a Ha filter ahead of the lens or telescope?

Cheers G-)

I had a bit of a Google (I'm having a slow arvo) and found a company called Optolong which seems to produce clip in filters for some Nikon cameras. The reviews of quality are mixed (though not sure how many are first hand) but it seems some are saying they're infringing some of Astronomik's patents. Though if Astronomik don't make Nikon clip-in filters then you don't have much choice I guess...

Look on the left, about half way down, on this page and you'll see the clip-in filters:

Interestingly they make clip-in filters for full frame Canon too, which Astronomik didn't do last time I checked.

Interesting but it is a shame its only for two models of Nikon. My understanding has always been the distance between the lens mount and the focal plane differs and theres not enough room on the back of a nikon lens to safely attach a filter without possibly damaging the mirror. So those two newer Nikons must have an internal change that allows a clipin filter that isn't in the way. Or maybe its all down to astronomik's monopoly?

I have used the CLS Optolong filter for a D7000 and sent it back soon after.
It doesn't fit properly (at least the sample I had didn't) and it ended up getting damaged. At one point, I couldn't get the lens off the body, as the filter had become wedged.
This was almost a year ago I think and they may have changed the design since, but I'd be cautious.
Good luck
