Hi,

KStars can hide objects and allsky overlays when I move my view. Is it possible to activate this feature for zoom too? The DSS colored allsky overlay (very cool feature btw) is activated on my computer which makes the zoom very laggy (even on my notebooks i7 cpu) and I zoom too far in/out. There are no problems if I deactivate the overlay.

I started the thread, went to bed and woke up with a new feature in KStars - Thanks a lot! :)

Hi,

some weeks ago I was looking for C/2016 R2 (PANSTARRS) in KStars but I couldn't it. So I checked the comets.dat and it seems there are only ~443 comets in the list which are all periodical. So I looked up the JPL query and there is a filter on ksutils.cpp:1253

QByteArray query("obj_group=all&obj_kind=" + kind + "&obj_numbered=num&OBJ_field=0&ORB_field=0");

obj_numbered is set to "num" which means there are only official named comets selected:

And finally, the numbered state can be "numbered" (meaning the object has been officially numbered by the IAU) or "unnumbered"
( ssd.jpl.nasa.gov/?help_sbdb_query )


I just changed obj_numbered is to "all", recompiled and got about ~3500 comets. There should be an option (checkbox?) to add non-periodic comets to the list.

Indeed, he Pro model only removes the additional glow on USB 2.0 ( zwoug.org/viewtopic.php?f=21&t=7543 ).
At first I had some dark corners after dark calibration but there was just a problem with the right temperature (-17°C instead of -20°C). Now, with same settings/temperature, the glow is gone :)

ZWO released an ASI 1600 Pro two weeks ago that has an DDR memory buffer to solve the amp glow problem. But there won't be an upgrade for 1600MM-Cool to Pro ( zwoug.org/viewtopic.php?f=21&t=7528 ). I bought the camera about a month ago, so maybe I will ask my dealer if there is an option to replace it with the new Pro model.

Yes, the fan is active and the temperature changes. It gets up to ~37K below ambient temperature. I got the ZWO power supply some days ago but the glow is still visible :(

I'm using USB 3.0. The glow reduces with bandwith=100 but is still visible. Maybe it's a power supply problem: zwoug.org/viewtopic.php?f=21&t=7469
I tried a 12V 2A and a 12V 10A power supply with same results.

Hi,

I just took some images with an ASI 1600MM-Cool some days ago. I found amp glow, especially in the right upper and bottom corner of the camera in _some_ images. It seems that all images with exposure times of 300s have amp glow while images with 60 or 180s don't have glow (at least I can't see any glow).

Is this a driver problem? I'm using the latest driver from repository.
Gain=139, Offset/Brightness=10, ccd_temp=-20°C

I just took a 600s darkframe with same settings (normalized):

I patched the kernel and uploaded the "not compatible" firmware to the cam but the error is the same. Then I plugged the AS120MC to USB2 port and it's working. The 1600 is also working on USB2 so I think there is something wrong with ODROIDs USB3 drivers.

Thanks for your input!

I'll try to patch my kernel. But this is only about USB 2.0 cameras.
It should'nt affect the ASI 1600 with USB3 that shows the same error.

I have a similar problem.
My setup is:
Odroid XU4 Ubuntu Mate 4.9.52-66 (armv7l)
Indi 1.5.0 from repository
ASI 1600MM-Cool attached at USB3 port
-> ASI 120MC attached at ASI 1600 hub
-> ASI EFW attached at ASI 1600 hub

The filter wheel is working well but camera exposures don't work. I'm getting [ERROR] Exposure failed after 3 attempts. I tried other USB ports - same problem. The 1600MM-Cool was working with Odroid XU4 Ubuntu Mate and Kernel 3.10 but the 120MC had the same exposure error. I also tried the compatible firmware for 120MC - no change.
The setup works fine on my Laptop with Linux Mint and Kernel 4.10.0-35-generic so I think it's an ARM problem?
