IR Moon

[kev533]

During a photographic course I completed recently I had a Nikon D70 converted to only take IR photography. That is what the red moon is attached, not PS. Is there a use I can put my camera to in regards to using it for astro imaging? Also, I can focus my canon 5dmk2 when its attached to my SW200p via a t mount, but I cannot seem to focus my IR modded Nikon, any help would be appreciated. The photo was taken via camera lens and tripod. Kev

I am looong way to being an expert but isn't this a Newtonian telescope? I think I read somewhere that the Newtonian telescopes do not have sufficient "focus travel" to be used without modifications for astrophotography. I think using eyepiece projection technique might fix your problem. If not maybe making physical changing to the telescope ( which might be tricky...).

razvans is right I think. I can't get my dslr to focus on my dob either when it's attached directly. I put a barlow on it and that works well but does restrict the views a bit. The only other reasonable option is to change your focuser for a slimline? one that lets you get the dslr closer to the tube.

The other option is to move the main mirror up the tube slightly. There are a couple of ways of doing this but I killed three birds with one stone and installed 6x longer, stronger springs at the same time.

I've got a canon 1100d an have no probs focusing with my 200p (unmodified). can't help you out with the IR camera though.

Nice moonshot by the way.

Cheers guys, I have no problem either with the canon, its the nikon that won't focus. I don't really want to move the mirror as then presumably my problem will be the other way round.

Many thanks

You could move the mirror up the tube or change the focuser to obtain focus with the Nikon and then use a small extension tube to obtain focus with your other kit.
