I have completely rebuilt mine with the main change being a liquid cooled heat sink. Before it would cool to -20c and then the temperature would slowly climb as the heatsink became saturated. With the new heatsink I now get -30c and it holds even with the voltage backed off.
Just need some IPA to see if vapour trails can be seenI have built one but made a few modifications. I found that the 1 ohm resistor had to be increased to four ohms with a voltage of 10.5.
Pulls just over 6 amps and cools down to -22c with a room temperature of 25c
Have had to set it to one side for the moment but will work on it again soon.Attachments:
I had trouble seeing it on my monitor so had to locate the galaxy NGC2146 and move it down a bit to be sure I had the right bit of sky.
Taken with a 10 inch RC and ASI1600 mono with RGB filters
60 two minute subs with IR filter and 10 two minute subs each RGB
In the image its at the 1 o’clock position near the topGiven our species desire to name and catalogue everything it is unusual that this one got missed. Its now in a catalogue we started as SNG20221 !

Here is the best we can do on the object.

The data was collected with the dual Esprit150/IMX571OSC/UV/IR cut filter rig over two nights 5th and 12th November, it comprises 204 x 2 min subs, calibrated with Darks, Flats and Dark Flats. All data was collected between 19:00 hrs and 24:00 hrs.
Imaging location: Long -2o45’41”, Lat 52o40’31”
Thank you both for looking at this. I am waiting for an email so I can furnish the imagining data etc.
The dual rig will have its cameras changed tomorrow as it looks like it will be clear here. These cameras will be better suited to improving the detail of the object and my RC will also be fitted with the same camera. As soon as the data is processed I will post the image.

Just put the Atik software on and it now has 33.5gb free. Even allowing for a few Gb for windows it still has plenty of room.
Images are stored directly onto a 32gb Toshiba memory stick and processed using APP on a laptop.
Also from memory I thought it was a 8gb ram but its 4gb. The model is a NEO Z83-4 Plus with 4GB DDR3L + 64GB eMMC 5.1 windows 10 pro (64bit
I have to load some more software on it so will report back. I must stress that its a command and control pc only with no image processing capabilities other than that offered by Sharpcap.
From memory it has the following astro software installed
Sharpcap 3.2, ANSVR plate solving, PHD2, EQMOD, Hitecastro focuser, and C du Ciel
I use both. The NUC states 19 volt DC but runs quite happily on 12 volts. The Minix has a better WiFi range due to its external antenna. The NUC is an i3 with 4gb ram and a 250 gb SSD. The minix is 8gb ram and a 64gb SSD. Both run windows 10 pro and I use Windows remote desktop to connect and control.
It only appears in the first luminance sub, But its trailed and is clearly not a hot pixelEnlarged image attached
We took 2 x 300 seconds in luminance, RGB. 20 flats and used library darks
Update….I am travelling up to Thirsk tomorrow evening and will take a look at all the images we took. Will post update.
I am new to meteor detection so I appreciate the data posting. At least it looks like I am getting reasonable results. I tried the auto recording software HROFFT but the results I got did not compare with my visual analysis of the recorded echo’s.
Thanks.
As its a military installation my guess was that they would not divulge operational details so my best hope was that others monitoring the station would confirm that it was down.
Many thanks for responding
