Thank you WSG!

 

I tried it but didn't work for me. Nebulosity stopped working after exposure. I think because i tried with trial Nebulosity4.

That is a pitty that it apparently won't work for you. Just to me sure that you did it the same way I did here a more detailed description:

1. Installation of Nebolusity and the additional driver for it to act as a ASCOM camera for other Tools
2. open Nebolusity and connect to cam84 ASCOM Driver
3. take 2 or 3 one second preview exposures with with Nebolusity to be sure you have a stable connection to cam84
4. Nebolusity is now inactive and waiting
5. open Sequence Generator and select "ASCOM Camera Driver for Nebulosity" as Camera.
6. make your exposures as required with Sequence Generator

 

I use a 64bit Windows 10 Laptop for this.

 

I do not think the trial version of Nebolusity causes the problem. As far as I know the trial version only disturbs the taken frames when stored with some stripes.

Does anyone still have a lead on schematics for a CAM10-R board? Many of the parts on the source list are outdated but going to try to build the CAM10-R, since I have a few MT9M001 color sensors. I can still find the original CAM10 schems on astroccd.org, but the cam10-r board was buried somewhere in a russian/ukranian astro forum that today I have lost track of. Has anyone been working with this lately? Trying to start off with a smaller build.

I was able to grab this bunch of files, for the Cam10 10R ... dunno if they're of use ...

 

Cam10 10R:

Holy jesus....I cant belive what you guys are up to here. I just read the whole thread in one sitting. The images you guys have taken so far are out standing! especially for a color cam! unreal.

Somebody please help me! My new cam86 has a problem. The histogram is fragmented, camera has only a few shades. The minimum adu is 1028 wiht or without sensor, no matter if i change the offset. Please look at the link:

https://www.kephost.com/image/EzXS

I have 3 panels and each has 8224 ADU minimum without sensor.

DD13 is warm, but the 5V is stable 4.980V.  Overall current on 12V is about 120mA.

Which software you use ?

With CAMView it's the same?

Tried with maximdl, nebulosity, sequence generator pro and cam86 view-01. All the same. Tried may firmwares and ascom drivers. I checked 3 times all the components all the 3 board but nothing.

You see my arms, face and tshirt.

The 3rd AD9826 works fine. First i soldered it before the other components and it is electrostatic discharge sensitive device, so maybe i killed it. The second ic is a desoldered from other device. The third is a new.

Finally here is my camera. Fully sealed, tube filled with silica gel.

I've got two cam86 boards waiting for sensors.

 

Hopefully all goes well, lol I'll report back when I get a sensor in place.

Added a sensor to one of them, and it looks like things are working. I am able to take photos with it while holding a lens above it laugh.gif

Interestingly, I did not need to do anything special to get the sensor out of the metal housing, it popped out on its own. The epoxy residue is still attached to the back of the sensor though. 

 

 

Anyone have ideas on removing the epoxy residue? is DMSO the only option?

DMSO is working very well, and is the only known option...

(Congratulations...)

You might try a paint stripper containing methylene chloride for removing the chip from the carrier and removing the residue.  I had success with such a product and it was available at a local hardware store (at least in the US but is banned in the EU.)

 

See an earlier post: https://www.cloudyni...mera/?p=7270629 for more details.

Thanks guys, I'll see what can be done with paint stripper before moving to DMSO.

 

Does anyone have any recommendations on how to mount a T-thread to the enclosure? I've seen a number of approaches from 3d printing to custom milling an aluminum connector. Unfortunately, I don't have access to a lathe or anything that would allow me to create this component. Would anyone be up for helping me out?

Here is a thread I stumbled across where someone was able to cut large diameter threads without a lathe.  Rather ingenious solution, another technique one can put in one's tool chest.

Grab a M42 to T-mount adapter off ebay.  Threads on both sides are the same diameter, but different pitch.

 

https://www.ebay.com...5.c100005.m1851

 

Enlarge the hole in the case so the adapter more or less screws in, then epoxy into place this something like JB weld  (metal filled epoxy, might cut IR leaks).

 

On mine I took the T-mount ring out and just mounted it, but that's in a machined housing.

 

As an additional FYI, extension tubes are also good sources of lens and camera mounts.

You guys are awesome, thanks for all the great suggestions!

 

@gregj888: do you have any photo's of what you ended up doing? Did you custom make the entire housing?

My cam84 is still a work in progress, however, my plan as been to use macro extension tubes as the basis for the connections (or possibly the mounting plate from the sacrificial camera.)

 

I am also using macro extension tubes to build a Dave Groski inspired H-alpha setup.  That's a story for another thread once I manage to make some more progress.

Zfed,

 

Housing photos on page 37 of this thread;

 

Electronics are here, cam 84-   https://www.cloudyni...uild/page-2?hl= cam84

 

The camera wears white powder coat now.  I think I've posted that but didn't see it   It's a little hard to see in the photos, but there's a water channel (largish round holes on each side of where the wires come out.  Then there are small holes behind the sensor (well peltier) to provide water channels behind the peltier for back side cooling.

 

Edit- added photos

Nice work greg! That is one professional looking camera.

 

Did you end up water cooling it?

Yes, I'm a fan of water cooling for cameras.  No vibration and much easier to reach lower temps with the peltiers.

I have idea use raspberry pi to use camera as standalone application without notebook in travel.

It is real? Or usb speed will not be enough to normal reading?

That problem looks familiar, see http://indilib.org/f...iver/12650.html

 

I had to do a sudo to run the server as root in order to not have the ftdi errors.  Evidently properly setting the udev rules may fix it also.

 

Don't know if a raspberry pi is fast enough but certainly worth a try.  I'd be curious to know if you get it to work.
