LPF for DSLR Prime Focus Imaging

[Astrosurf]

Hi guys, is this LPF OK for imaging at prime focus with a DSLR camera? I assume I would use the 2" but how would I connect it? FLO aren't answering the phone so I thought SGL would know!

I am not sure how good the SW LP filters are, but I think they may be intended more for visual use. I believe 2 inch filters can be placed in the T-adaptor.

Many people think that the best results are archived with an Astronomik ESO filter clip.

If your DSLR has been moded, you need the CCD version.

I use one, and they work very well but at £128 are much more expensive.

If you have a 2" focuser and a 2" to T thread adaptor, then the standard astro filters just screw into the front of the nosepiece.

SW LPF is fine for imaging (though there are better options as above,) see here for some info - clicky

As to connecting it, you could use a camera to 2" adaptor which should have a filter thread on the end. Something like this - clicky 2

Thanks guys. I'll buy the 2". Can't wait!

It'll work pretty well... I use the 2" fit variant on slower optics, most of my DSO images are shot with it. It's not as good as a CLS, and I use a CLS Clip on faster optics. I guess a lot will depend on your LP situation. Still, it's cheap and works. If you have a 50mm prime lens (like the f/1.8) you can fit the 2" filter, with a step ring, onto your lens too.

Actually, I'm glad I got through to FLO as, with this filter, you need a nosepiece to attach to my SW 200P EP holder and it forces the camera too far back so it won't focus. Can't use the filter I'm afraid.

Will have to go for the expensive clip-in.

Well done FLO.
