That shutter is for an aps-c sized sensor which is a tad smaller. Possibly a shutter curtain from a full sized sensor like a Canon 5D, 1D, or Nikon D700 and D3.

Another option is to bore out the plate on the lathe to accept a Canon EOS to Nikon adapter and epoxy or screw it in place.




I just applied Keith's idea to the adapter plate that came with the camera. Check out the next two photos. I have a small lathe in my garage that did the job nicely. The center ring is from a T-Ring and is held in by three 6-32 set screws. It appears to be quite rigid and I have no issues about this set up supporting the camera!

If any of my fellow cloudynight'ers had ANY doubts about the incredible bargain these camera were with a $500 "buy it now" price on Ebay , I just noticed the same camera that was being auctioned went for $880. This would have been beyond my means at this time so I am quite please with my purchase!!!

Right again Jerry, I posted that as an example. I found and purchased one of these http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=320497395339&ssPageName=STRK:MEWNX:IT

There appears to be several more available. I was thinking test to see if it works on the Quantix circuit and maybe use black poster board or some other spacer, and some spacer bushings to open the faceplate wide enough to accept it and use longer screws to tighten it down. Kevin and Keith my have other suggestions.

Don't know the voltage the 35mm shutter operates at. Maybe you can help me with that by looking at the color of the leads.

Wow, you gotta wedge for that monster? BTW thanks for the 411 on the chip architechure. Read that stuff some time ago but have never been able to afford a good CCD so I didn't pay much attention to the material. Now it all makes sense.

Going to build a wedge soon. Dont want to mess with a field rotator.

Got my camera yesterday. Hooked it up and am having a hard time getting an usable image.

That makes sense, I figure there will be a learning curve in order to get light cone(CCD distance),focus, gain etc. adjusted in order to get imagery down. Best of luck, sounds like you are ahead of us. Look forward to seeing the first images posted.

BTW, just to help other users, while I was researching the chip architecture Jerry mentioned, I found Apogees CCD University link to be helpful http://www.ccd.com/ccd102.html
I noted that because we have no anti blooming capability we will be doing shorter exposure stacked images. Coming from a light polluted DSLR imaging experience this is second nature for me. Others may not be familiar with this. The stack method helps kill the blooming problem per Apogees web site. Hope this helps.

One thing I noticed last night while playing with it was there is no IR cut filter. (IR Cut is an option) This I am happy for as I like to play with IR, but some may need to use a IR cut if you have additional glass optics in the system like a flattener or a field reducer.

OK, has anyone actually gotten an image out of one of these things. I am not getting anything useful.

Yesterday I made the same mod as Kevin and hooked it up to my AT65EDQ on an LXD75 - I still need to get a long cable to operate it on the main setup, so I just set the LXD up on my deck to try a couple of quick shots. Nothing fancy, just aimed it at Cygnus to try it out.

Here's my image - 10X1m - I think I had a gain setting wrong or I shouldn't have saved the files as tifs, because I had very little dynamic range, although I could see a bit of nebulosity in the images when they were taken. Anyway something wasn't right but the camera appears to be free of major defects. I intend to completely characterize it when I get a chance.

Looks like the EDQ carried it well, No slipping in the prime focus adapter under the weight of the cam? I was wondering id the EDQ if the EDQ would tolerate the weight. Any problem in that respect?

The camera weighs about 4.5 lbs according to my scale. I didn't notice any slippage, but then again I wasn't running it very long and it was only about 43 degrees alt. I don't have a shutter yet - I ordered one from Surplus Shed and I intend to design a filter wheel and housing that will also hold the shutter.

BTW astrometry.net analyzed the field - NGC 6910 is an OC near Gamma Cygni in the lower left corner and NGC 6914 is a nebula just below center.

Hope to get some better pix in the coming nights! --Keith
