Agree, I wouldn’t rely on Ricoh fixing a bug in the SDK or K-70 firmware.
Getting PKtriggercord merged with INDI would be fantastic, Andras Salamon is actively working on it from time to time.
I got this from him when I asked him about the bulb mode in PKtriggercord:

The new bulb mode is defined in the (creatively named) bulb_new method: github.com/asalamon74/pktriggercord/blob...cord-cli.c#L335-L352
The k_70 line in the pslr_model.c ( github.com/asalamon74/pktriggercord/blob...er/pslr_model.c#L980 ) defines which mode should be used.

The new bulb mode requires settings buffer (not status!) reading/writing. Camera specific field addresses can be found in this file: github.com/asalamon74/pktriggercord/blob...pentax_settings.json

My process is the same Karl, except from the focusing. I adjust focus with the camera disconnected from the RPi: bright star, liveview, bahtinov mask or just full zoom and adjust, set exposure time and ISO, connect.
I have been in contact with Andras (PKTrigger) and Marcus Meissner (gphoto2) with regards to the K-70, Andras has a K-70 - would be nice if the two of them could work together to make it work.
Or even better, if you could make it work with the Ricoh SDK :-)
A user asked for a bulb mode fix for his K-70 and Oly OM-D E-5, a solution was created for the Olympus, the same could be made for the K-70: www.indilib.org/forum/development/4640-r...mark-ii.html?start=0
There's no problem with 1min+ exposures with the K-70, I usually keep the ISO at 800, no long exposure noise reduction etc. (everything turned off).

I'll give it a go - I have a K-70.
The deal breaker for me is the lack of bulb exposures for the K-70. It works with PKTrigger, but for some reason it's not working when using kStars/INDI (adapted from PKTrigger).

If you use both a ZWO camera for imaging and guiding, the guidecam selection will be deleted in the profile editor.
It will only show the ZWO camera for imaging.

The ASI533MC Pro works fine on SM/RPI4 - I got the 533 last week, have used it the last two Fridays (yep, no 1 month of cloudy nights when buying new gear :) )

Shooting right now, I have had issues with the 120MM mini several times tonight, restarted SM, unplugged the camera etc. to get it running. There’s no apparent way to make it work, streaming does not seem to work every time.
I tried to enable logging, but didn’t work - just realized I needed to enable it in the “Logs” menu :)
Next time.

You could test it any time, I’d rather spend a cloudy evening on preparing for clear skies :-)

I had the same experince Friday night, first time I used my RPI4 with the latest Stellarmate/KStars version. The ASI120MM Mini (guidecam) attached to my new ASI533MC Pro (first light) - no pictures from the 120MM. I then attached the 120MM to one of the USB2 ports on the RPI4, same issue - no pictures.
Then I tried to do some streaming, that did the trick, I was now able to get pictures from the 120MM. That's what I did the rest of the evening if I rebooted Stellarmate (first time setup).
Looks like clear skies tomorrow evening as well, then I'll check if I can do the same with the 120MM attached directly to the 533MC.

Keld Henningsen replied to the topic 'Pentax kp' in the forum. 3 months ago

I doubt it, I got the USB Product ID for the K-70 included in the Pentax library - there's no KP USB Product ID at the moment. The USB Product ID can be found if you connect your KP to a linux machine and type lsusb at the command prompt - then it shows USB Vendor and Product ID as ID vvvv:pppp.
Send the numbers to Marcus Meissner, meissner (at) suse.de
github.com/gphoto/libgphoto2/blob/master...ibs/pentax/library.c
That's the first step, then Andras Salamon most likely needs to update PKTriggerCord - a Windows/Linux program able to remote control your Pentax camera, you can download it here and test it on your KP: pktriggercord.melda.info/
It can be done, the question is the timeframe.
I use Stellarmate on a Raspberry Pi together with my K-70, it does require that I set exposure time and ISO on the camera before I start shooting, it cannot be set from KStars yet. Otherwise it works.

My ASI120 mini works just fine with Stellarmate on an RPi 3. I use it as a guidecam.

How many of you use a case with a cooling fan and also confirm adequate power supply


I have the RPi 4b ps and a case with a cooling fan/heatsinks on cpu, usb controller and ram.
There’s quite a difference between active and no cooling, check this video: youtu.be/e6mWImsF9iI

I'm trying to figure out why my VK-162 GPS fails to work with 1.4.4, but works fine on 1.4.3. It does connect, then nothing further happens. On 1.4.3 I get a GPS fix within a couple of seconds.
The 1.4.4 GPSD log tells me nothing, I've tried to install Wireshark to see what's being transmitted on the USB - but no success (access rights etc.).
Any suggestions? (troubleshooting/logs to check etc.)
