Hi there folks,
I've been trying to read up on the 250 someodd pages of this discussion, but I'm sure that I'm out of date.
- Aurora on this board turned me onto the E4 camera, which I now own and have hacked to be an E8.
- I have a specific project in mind - some of you are working on related things - -high res panagraphic images.
- I have a very long focal length germanium lens (it's somewhere between 1500 and 1700mm focal distance, F1.0)
- I had gotten it basically working using a pathfindIR, but being unable to disable automatic range/gain on the camera prevented me from doing panos.
- I have built a very high accuracy rotation stage which can support the weight of this 30 pound lens.
My questions for the group:
- Has anyone retrofit the lens assembly entirely on their e4? Is this a reversible prospect? eg: can I just remove the lens and resemble and have any chance of putting it back again?
- How does one input the flat field calibration data, or perform this cal?
- I may have access to a reference black body for absolute emissivity calibration, but this really isn't that important to me - - seamless stitching is, but having access to this might help.
- Mildly related, my hacked e4 shows a few pixels being "off". See attached - three shots of the same wall - - you can see some "spots" on the upper left of the image which read about 1c cooler.
(this doesn't seem to be related to external muck on the lens or anything. Has anyone encountered this before?
As this is my first post, I thought I'd share a bit about me:
- I work with lasers a bunch. No, not "laser pointers". Sometimes for fun:

- Milling, soldering, coding, hacking, etc.
- photography - -mostly underwater.

I've had this project in the works for 3 years trying to make use of this huge lens I have, and now this looks possible. Super excited, please let me know how I might be able to give back to this community for it's support.
