I drew up made the adapter plate for the shutter. It turns out two of the holes in the existing bolt pattern for the lens mount match up with two of the holes on the Ilex shutter. If anyone want the drawing for the adapter plate or the hole layout on the shutter, let me know.

Chewed the part out on the cnc mill and counterbored and tapped the needed holes. We are having some stuff heading out to anodizing at work so I will throw the plate in with the rest.

I got the little DC/DC converter this afternoon. It looks like it is going to work great. I just breadboarded it with a bunch of jumper wires and it triggers it real nice. The converter has an unregulated output. The 48 v line floats about 80v with no load so it charges a capacitor real nice. The pulse opens it and one of the micro switches in the shutter switches the coil to 5 volts to hold. Now I just need a tiny little relay to get it all in the shutter.

The new parts compared to the "plate" that came with camera.

That's definitely the way to go, in my opinion - much cleaner than my hack. Very nice! --Keith

Got my docking station for the thinkpad today. Got the card installed and ready to go.

Almost had my shutter working. Goofed somewhere and shorted out the dc/dc converter. Another is on its way. grrr...

Got my shutter together today and it works nice. Still have not hooked it to the quantix but there should be no problem. Heres a pic and a video. The wiring in the shutter turned out to be a mess. Oh well.

Here is how I am now, ready to go. Thanks largely to Kevin and his awsome housing. I am including pic of the camera connector, The shutter and housing (I blacked every thing to avoid internal reflection), and the complete assembly.
Working on an old PC to run the cam for now. My son got me the ITX motherboard and a hard drive for fathers day, so I will persue that build when money permits.

I decided to make some chips today. I had drawn up the modifications to the old lens flange I needed to make and plugged them into my CAM software and made up some toolpaths for the mill. First I made a fixture plate to mount the lens adapter to. Took a chunk of used 1/2" aluminum and faced it off and drilled and tapped the 4 holes that the plate mounts with. Mounted the adapter down and loaded the g-code and crossed my fingers.

First with a 1/2" variable flute end mill the machine faced off the nose to the new height (Which was calculated with the index of refraction of the quartz window on the camera to be the same as the standard Nikon flange focal distance), then the inner clearance was cut away and the lever clearance was cut.

Next a 3/16" 3 flute was used to cut the remaining profiles needed for the Nikon flange.

Last the 4 mounting holes were spotted and drilled #55 for the 1.6mm screws that hold on the flange.

Looks like everything is where it is supposed to be. I dont have a tap for the flange screws nor do I have long enough screws to mount everything to the camera so that will have to wait.

Here is some cnc porn:

Wow, nice work!

I'm sorry I haven't been much help lately, been busy with non-astronomy matters, like work...One thing that I did was I bought a new PC to run the camera. But I didn't want to spend a lot so I bought an "off-lease" IBM Lenovo 3GHz Pentium 4 with 2GB of RAM and Windows XP Pro SP3 for about $250. from TigerDirect. I ended up replacing the hard drive with a 1 TB drive and partitioned it to run Ubuntu Linux as well as XP. I found that I had to use an older driver from the Photometrics website in order to connect to the camera but it works great (my old machine wouldn't always connect, but maybe I should have tried an older driver on that one as well). RSImage works fine but MicroManager doesn't (it can read the camera but doesn't operate the shutter). For the moment I'll use RSImage but it will only take 10 exposures in a sequence due to limited memory allocation (and I haven't figured out if there is a way to change that).

When you take a sequence and save it as a tif file the images are saved as individual frames. To break the file into individual 16-bit tifs I wrote a macro for ImageJ (which is freeware and I highly recommend downloading it). The macro:

open();
dir = File.directory
Stack.getDimensions(width,height,channels,slices,frames)
run("Stack to Images")

for (i=0; i<slices; i++) {
name = getTitle();
saveAs("tiff",dir+name);
wait(500);
close();
}

(Please note here that I am as much of a hack programmer as I am a hack machinist...Pros please don't laugh too hard...)

DSS and Nebulosity work fine with the 12-bit data. I scale the data by 16x in Nebulosity to make it a little easier to use the sliders but it isn't necessary to do that.

This is 25m total of LHaGB of M57 at f/10 in the EdgeHD:

CCD temp. -30C
L: 10X30s no binning
R(Ha): 2X300s 2X2 bin
G,B: 10X30s 2X2 bin

Only slightly cropped for channel misalignment. Some dust rings are visible. Didn't take enough blue data but this was only a test anyway. Full image at Flickr. --Keith

oooOOOOOooo! to both of you, very nice! And BRAVO to the first well done LHaGB. FOV is killer!
