Has the hackabiliy of the E4 made you buy one :  

Yes, I was already looking at the competition at a similar price, but the hack swung it to E4
241 (26.5%)
Yes, I'd not considered buying a TIC before, but 320x240 resolution at this price justifies it (as either tool or toy!)

The type of telescope he's talking about uses curved mirrors only. The only lenses would be the eyepiece but what's he's doing is called prime focus where you remove the eyepiece and focus directly into the E4 sensor. If his mirrors reflect LWIR it should be theoretically doable. I'm not sure though that it would be worth doing because the device would not really see through the atmosphere well enough to provide any data. He could use it for long range terrestrial viewing though if the mirrors work. But the temp readings would be wayyyy off.

No lenses inside,  only two mirrors and they are highly IR reflective.

Odd, can't no longer access hidden menu, beyond 'camera information' menu, I have E4 1.2L    2.3.0 software. still original.
I did install drivers and download some images from the E4 to my pc.

I've been meaning to try this, but I was thinking to use one of the cheap ZnSe "close-up lenses" as a primitive "eyepiece". But it's not likely to happen in the foreseeable future.

Nearly every reflecting telescope uses a thin front-surface layer of aluminum, and aluminum's reflectivity is plenty high throughout the IR range. (Its emissivity is probably plenty low, too, which should help.) My only concern would be whether a very thin layer (much thinner than a single wavelength) would have different reflectance properties; I doubt it, but this is way outside my areas of study.

At 10-20x the normal wavelength, your mirror will appear superb, but you can also expect only 1/10-1/20th the resolution that you get in visible wavelengths, if I'm remembering my optics correctly. It'll likely be a good match for the low-resolution detectors we're working with, though.

The one thing I've found puzzling is "what would I look at?" Besides the Moon, which shows up clearly on a 320x240 Flir imager, I'm not sure what celestial targets would be bright, warm, and extended enough to show up. What are your thoughts? (Perhaps this would best be discussed on an astronomy forum...!)

Good!  :D hidden menu is back, it was and is: 'camera information' menu, then 'model' menu, then press right button for 10 seconds :palm:

The moon in the focal plane of my telescope is 13 mm, (on the sensor), in the E4 the whole image would be the moon!
With just the E4 (un-mod) it is only a few pixels...
Other target would be the nebula like the large Orion nebula, with the E4 the nebula would be gone, A galaxy could be awesome.
I have made a few Near IR images with my IR modified DSLR camera, tomorrow I will upload here a example.
btw, many of the images from the Hubble Space Telescope are made in the Far Infrared.

Today I bought a screen protector (for a Apple S6+) 2 for 10 Euro.
I also need a tool to unscrew the lens, I found some 3D print drawings here on EEV, lets pimp Flir!

Ugh. Good luck tracking them. (Yes, there are advanced amateurs who can do it. I'm not one of them.)

But my E4 having intermittent issues with shutter laggy or even unresponsive and occasional lockups - so I want to try the 1.22 f/w upgrade to see if that makes any difference.  Thanks again!

Please keep us posted in case if you will upgrade FW1.98 HW1 E4 to FW 2.3 and then get the high res.

Hi!
I'm new to this forum.
I haved... an higres E4. I upgraded to fw 2.3.0 from fw 1.22.

I try to apply hack v04.zip and the hack don't work.

ISS is 100m wide or so, but still a point in the sky, image is shot with a telescope from the ground and show ISS (Space Station) transit the sun.
(Google image), a transit takes only a few seconds.

Sorry I have no good IR images I promised yesterday.

Thanks DaveWB, I want to use the TIC for my hobby astronomy, I have a large Newton type telescope which is highly automated for remote imaging.
Some parts of the telescope are heated to prevent dew, but for optimum imaging results the telescope should have the same temperature on any part.
The TIC can show us (I'm not the only user) heat spots.
And we can use the telescope as 'lens' for the E4 by removing the E4 lens and make a special adaptor to attach the E4 on the telescope focuser,
having a 1550mm F3.8 mirror 'lens' for a TIC!, for several reasons this isn't easy, we must also modify the telescope in some way.

The image show the telescope still inside my home.

Hello, I will follow your work, I made a quick and dirty test with my telescope:
https://www.eevblog.com/forum/testgear/flir-e4-thermal-imaging-camera-teardown/msg435324/#msg435324

By the way wonderful telescope you have there, is a beast, 16" ? Mine is 8" F5

Just curious the temp scale is manual and the smallest difference is 2 can this be made smaller and can the maximum 280 be higher ?

I need the file /FlashBFS/system/web/service/Diag/Reconfig.asp", or better yet a copy of the entire web folder of an E4/E5/E6/E8 that has a working "Activate Service Mode" web interface menu item. Or better yet a copy of the entire filesystem. Please. Send to jorge at jorgechamorro dot com. Thank you!

Did not you read the Readme in v0.4 package... What is your conf file length? It says if the conf file length is not 6608 then this hack is not for you.

I have a 2.3.0 but its web folder comes almost empty (?). I'm trying things with a webfolder I found in this thread, but it's missing that file ("/service/Diag/Reconfig.asp"), which is referenced by the service menu item button that's setup in web/service/inc/servicemenu.inc#L164:

Code: [Select]
if ( CamType == "Z" )
  menuRow("Activate Service Mode", "/service/Diag/Reconfig.asp", "submenu1", selectedMenu == "mnuDiagReconfig");

I'd need a copy of a complete, working webfolder from a previous FW version...

Thank you.

There is Flir E4 owners who are testing my new "2.3.0 Menu 2014 Advanced update".
Some things with this may be hard to understand. I can give a little guide from things
I figured out so far. Sometimes camera needs restart too... there is windows : )

While reading this I was wondering where to fetch that file until realizing that you probably didn't
post a preliminary  "2.3.0 Menu 2014 Advanced update" but must have sent it around
in private - this way you have the overhead of distributing the files and it's limiting the people
who might take a look at it (can be helpful or not).

While I'm already writing... here some old info that might help: with advanced measurements
I had the strong impression that we can't fix stuff anything inside the bytecode where the
camera will lock up etc.. It probably never had to do those functions and the only reason why
those functions exists is likely just due to the fact that developers used a common source.

In my experience any function depending on the preset.d folder or -more generally said-
writing some files seemed to be _at least_ a bit sluggish (most likely due to the extra I/O).
IMHO there's a good chance that the Ex series runs a hardware that is simply not as capable
in regard to I/O performance as the higher models - thereby causing all sorts of "wonderful"
effects by running into deadlocks or waiting for the (slow) file-I/O-reply.

From my own experience the following did help a lot:
- clear versioning, describing version changes and keeping a backlog of what has changed
- openness (post everything, sometimes somebody else will be able to assist - helped me several times)
- some ignorance (you will get private requests like "I can't open cmd or copy a file but want to ..."
 
Last but not least:
Keep on going  :-+

When this is complicated and not easy to use and understand (but advanced users can handle this)
I didn't release it yet to avoid big pile of letters. But if you know what to expect from camera,
all this is working very fine in everiday use. Now I must only see what I must limit with conf and
what enable-disable befor to show it to bigger group.
If somebody like to play more with E4 where is 2.3.0_menu_2014 already and can replace files and
patch conf and restore it, I'm happy to share this update for testing.

I fully agree with Janekivi.  :)
Before distributing it has to be almost monkey proof. Otherwise it brings people in big trouble. And that is not what anyone on this forum wants. Now some people are already having trouble with the highreso hack. Mostly because they don't want to spend some spare time to read the former posts.
Sometimes because they are simply not able to understand what they are supposed to do.
To avoid too many 'crash questions' I think Janekivi is doing the right method.
Keep on going. We all appreciate your efforts.  :-+

Just a small update on cfccfg.py for 2.3. It now drops the signature/tail from the .cfg file. You can also make changes to  the .cfg in plain text before converting back to .cfc, the file tail is created with the proper file size info (the signature is set to all 0). Note that you need the "HIRES" patch  first in order to skip the CRC/signature check for this to work.

I tested adding a few lines to the .cfg file (comments, putting back 80x60 resolution...), convert to .cfc and use that on camera. Seems to work fine.
