Fantastic imaging! How well is the remote observatory working?

Thank you,

Remote observatory works almost every clear dark night.
Of course there are difficulties.
Recently cam8 died so I switched back to QHY8.
Also second setup require some improvement.
But I think this will be fixed soon :)

does this camera and its ASCOM driver work with Sharpcap ?

Yes, cam84  ASCOM driver works with Sharpcap.

But I'm not sure that it will be comfortable for deepsky imaging.

the images look good .If the ASCOM driver works, why would the camera not work good for deep sky with Sharpcap ? The sensor is great, dynmic range is as good as it gets for a CCD , A/D is 16 bit . Wht could be not working good ?

You misunderstood me.

Cam84 designed for deepsky imaging.

Sharpcap mostly designed for planet imaging (not deepsky).

You can take pictures with Sharpcap and cam84, but software designed for deepsky imaging (MaximDL, Nebulosity, etc) grant more options for imaging automatization.

I can not get my cam84 working with Sharpcap. With Nebulosity the cam84 works very good. Any idea what I might do wrong with Sharpcap?

Sharpcap does not report any error when connected to cam84. It simply does not get frames out of it.

I would like to use it for setting up the scope because Sharpcap has a Polar Alignment tool included.

For taking the real pictures I will use Nebulosity.

Which version of SharpCap and cam84 ASCOM driver you use?

I am using SharpCap 2.9.2877 and ASCOM Driver cam8s v1.0. When selcting this driver in Sharpcap reports cam is operational. But I get no picture.

Yes, there is a issue with Sharpcap. I checked with my old cam8 and Sharpcap 2.8 and 2.9 (now i don't have cam84, but cam8 and cam84 ASCOM drivers is mostly same). For some reason Sharpcap works with ASCOM camera class in other manner than MaximDl and Nebulosity... There is a topic for investigation and next cam84 ASCOM driver release.

Many thank for checking this issue. Now I know I am not doing stupid things that causes the problem.

As the cam84 is perfectly working with Nebulosity it is not urgent for me to get the Sharpcap issue solved.

If you find the time to fix it that, that would be nice. If not thats also ok. You did already so much for this project. I can only say many thanks to you and the others which developed cam84..

Wolfgang

Yesterday found workaround for SharpCap:

- connect cam84 to Sharpcap as usually;

- change exposure to less than 0.5 sec;

- press Show options button;

- image capture should start.

 

There is an issue with exposures more than 0.5 sec (observed only in Sharpcap).

great, the workaround is working for me. Now I have to wait for clear sky to check if 0.5sec is enough for the polar alignement tool of sharpcap to capture the necessary stars.

 

PHD2 seems to have the same problem. I can get only a picture there for exposure time lower than 0.5sec

I have not done much on my camera for a while due to work and other commitments, but we now have a very good system working.

 

Camera is working fine, we have replaced the rear cover with a solid copper plate and this handles all the warm side  peltier. Cold side peltier is as follows 20mm copper cylinder silver soldered to a 40mm square plate of copper. We then put a small 1mm thick thermal pad and this attaches to the peltier. The hot peltier side is thermal grease attached to the rear of the external copper plate, then we have the AMD stock cooling fan. We get a delta T of around 40 degrees with this setup.

 

Moisture control is handled by a closed loop system, the camera is sealed as air tight as possible. A pump rated at 20psi is used to pump air from the camer into a silica bottle through a 5micron filter and back to the camer. We tested this removes moisture in around 12 seconds of the pump running.

 

Some pictures,

 

We are now waiting to put the pump and various controls into one enclosure, just need a clear night to image the sky now.

Has anybody have Gerber fields for the tec board and thermal controller please. Hello everyone and to remove the sensor from the base I used Chemset AP 1105 epoxy stripper that only took over night and all the epoxy was completely gone..

I have a TEC controller/usb hub design I built but I'm still testing it. It seems to work fine now but I need to change a few things on the schematic and then the pcb. After that I will share my gerbers.

 

Have you had any luck with the tec yet?

 

 

I have made some changes and it works ok now,  I can offer the gerbers and bom up but I won't take responsibility if it messes anything up on the camera or host computer. 

 

 

Gerbers and BOM for the AUX Board with TEC controller and USB Hub.

https://drive.google...WhIR3BRcUE/view

https://drive.google...EVvZ05meEE/view

 

Use at your own risk, not been fully tested but as yet I have not had it fail on me.

 

The Atmel chip will use the firmware that Vakulenko wrote.

 

See here for the link to his firmware and page.

NOTE: cam84 ASCOM driver supports my TEC controller, so it is not necessary use TEC_control utility for cooler controlling (you can use MaxIm for this)

Unfortunately cam8 died (MAX743 failed) when I capturing M16 due dew issue, so I do not collect the planned number of frames for this object.

Well we did some tests with the camera with pump and all worked fine. Ccd temp went down to -20 ambient was 19.5 and was bone dry with our setup. We opened it after a 5 hour session and no signs of moisture.

On another note I have decided to build my own Aux board that is able to monitor the following.

Temp external and internal using onewire communication.
Rpm of fan.
Humidity of air inside the camera.
Temp of air inside the camera.
Pressure of the air inside the camera.
Pwm of tec.
Control of the air pump.

All these will monitor and keep our camera in safe limits. Communications over RS485 and I will make a GUI for the computer also.

The schematics are almost complete and will be using microchip pic24f to do all the work.

Hi
Some news on my attempts to port the Delphi code under any way to make it work with Indilib (3 methods, 3 fails) :

 

1- porting Delphi dll to C library, using opensource libFTDI
Translating original D2XX commands to libFTDI is difficult because of differences between methods to write a buffer : Pascal word vs pascal Byte...

 

2- porting Delphi dll to C library, using closed source FTDI D2XX
Easier to translate because commands are the same, but no more luck.
Camera opens and closes, many other things happens  (for example i think the initialization step is ok), but i can't manage to retrieve any data during reading when exposure is completed.

 

3- porting Delphi dll to Lazarus (Free Pascal) library,  using  closed source FTDI D2XX, calling this in C code
The best i can do is to open and close FTDI communication, but there is some kind of black magic within library usages, when (like here) a library is written in freepascal and called in a C program.

 

I think i'll soon give up, it takes too much time // i'm not skilled enough
