DSLR
« on: Dec 20, 2016, 09:48:19 »
Since the demise of my DSLR, I thought I would look out for a 2nd hand one as there are still some uses I might have for it, but don't want to spend too much for occasional use.

What would be a reasonable shutter count for a 2nd hand DSLR?

Things I still want to do:
Milky Way (never yet got a decent image of this).
Antares region, it's gonna take forever to try to do this with a mono camera, i.,e. FOV and opportunities as behind trees at home.
Plus others

I don't think Kenny's is modified Ivor, I was aware he was trying to sell it.

As an alternative have you consider buying an adapter to be able to put a camera lens on an astro camera? I've got one for the QHY8L it works well the only constraint with this approach is you have to manual focus and you can't adjust the F stop.

I have thought about that Ivor, but it's almost as expensive as buying a 2nd hand DSLR to buy all the components required.  Plus you can't attach a filter wheel to it so you have to have a separate slide in tray and another set of filters.  Too much palaver I think for only occasional shots.

An entry level DSLR should be fine to 100,000 shutter actuations.  I wouldn't buy one with more than 50,000 actuations.

This is consistent with the research I did. Mine (now sold) had 19022 activations but as you say was unmodified.

Well I have managed to acquire a Baader modified Canon 1100D with low shutter count, it is currently on it's way to me.

Also managed to find a buyer for my dead DSLR who just wants the body as he has a modified 450D (with cooling) but no case can you believe it?  And he's been using it like that!!!!

Yes I can believe it as my 450d has no body and is cooled, but  is in a plastic box.
Been like it  for  a few years now, and no I did not buy Carole's camera :lol:

That's funny - I had already guessed it was you who had bought it and that Carole was keeping it quiet.  So I was wrong!

The chap who bought my DSLR has managed to fix it instead of using it as a cover for his robotic cooled 450D (see picture above).  It was by no means a simple fix, he quotes:

I decided that the most likely issue with your camera would be either with the main board or with the power board side and since I was taking the body off anyway I researched how to strip it down into its component parts. I found really helpful videos and walk throughs, mainly concerned with carrying out the filter mod, and I swapped the motherboards over but the issue was still there. As a last resort I dismantled my camera completely and swapped the power boards over - and bingo - a working camera.

I am not sure if he still has a working "cooled DSLR", if he has swapped the power boards over.

I see - some kind of power board failure then.  Interesting that he managed to narrow it down.  I certainly didn't see anything obvious when I took it apart.
