I noticed my ZWO ASI183MM Pro camera fails to report its temperature. It says 0.0C no matter what!
I have tried reinstalling the ASCOM and camera drivers but no difference.
I connect my other ASI cooled camera and that shows the temperature and the temperature changes when cooling.
The camera has worked perfectly until last night when this occurred. Although I am still using the camera and the subs look OK considering the seeing is murky.
Is there something I am missing?
I finally had a chance to start my active cooling mod of my astro modded Canon 40D. Initially I started with designing the shape of the cold finger and creating a to scale template on paper...
I made two designs, one with bends around the sensor, and one which is mostly flat with minimal bends. I went with the latter since I figured that I will not be able to bend the copper plate with such precision using my available tools... ie two pieces of wood.
I cut out the cold finger on the copper plate and after bending the cold finger into shape, I realized that there was a bit of a gap between the copper and the sensor...
...so I cut out a piece of copper 1mm smaller than the sensor on each side and inserted this in between the cold finger and the sensor.
Hopefully (with the use of heat transfer paste) creating contact and being more efficient in extracting the sensor generated heat.
I used the existing screws to hold the cold finger in place, three screws should be secure enough to hold it in place.
Now that the cold finger is in place, it is time to put the camera together.
There is not much room inside the camera and so the mod is very tight.
The main PCB is a tiny bit offset and inserting the compact flash card is tighter than normal, as is inserting the mini-USB cable. At this time I was expecting the camera not to power on but...
... it's alive... ALIVE!!! I've taken a shot of the light without a lens and the white frame tells me that the sensor still works.
There is enough room to use the side connectors as needed. The most important connectors are the USB connector which will be used almost exclusively and the remote trigger connector which I'll use when I'm not using the laptop.
Part 2 of the cooled DSLR mod is a success, all that's left now is to bend the outside plate 90 degrees to the front, install the peltier cooler, heat sync and the temperature controller....
Decided to put cooling fans on my newtonians a 200pds and a 130pds ,used a 120mm on the 200 and a 80mm on the 130pds ,i used, Be Quite silent Wings2 fans they use rifle bearings and are so quite German made, i did the 200 first and was impressed with this make so ordered the same make for the 130 pds it comes with a lead with four wires but only needed neg ang pos so snipped other two out , made a disc from plastic and cut out around collimation screws on primary then used velcro to attach to OTA fitted a 2.1mm dc socket on to the disc then bought a usb lead to 2.1mm barrel though i may fit another 2.1mm socket on my power box and use 12v either way it works ,i used a dimmer on the 200pds but it doesnt need it and wouldn't use it again but its fitted now so will leave in place.
I have a simple question that I've not been able to answer myself about cooling..
Does it actually help if the ambient temperature is already very low?
My last two or three times out using my camera the air temperature has been below -1 deg C and as low as -4 from the cameras inbuilt sensor.
Hi everybody!! Just joined after lurking for a year.
I have done the filter removal as instructed by Gary Honis and was satisfied with the results. Only one thing I'm wanting to learn and that's how to do a cold finger mod on my canon 1000d.
I have found some links, but mostly any instructions I've found were outdated and removed from the web, so it's been difficult to find a mod to my liking with detailed step by step and supply list.
One of my main concerns is that I still want to use the side of my camera that has usb and the input for my intervalometer (currently unguided with no laptop).
I can do without live view as long as I can still connect the dslr to my phone on dslr controller for a bigger more comfortable live view.
Anyways I really need help in the right instructions to get this done. Any links, videos, or experienced instructions would be a big help and I would be very thankful for.
I'd also like to add that I would like to go light weight on the mod, so i don't have much trouble balancing the es 80mm triplet on an Orion sirius.
Trying my best at a budget to defeat the Texas summer.
