Same here. Down to -15°F without issues. All L-com USB3 cables other than one USB2 to a FlipFlat. Remote from yard to house with an ICRON 3104. Front Range in Colorado so very low RH.

My camera's USB2 cable has failed several times this winter. I replaced all cables last week and had several successful sessions until tonight. I don't know if it's the cable or the laptop.

I should also mention that on the AP1100 I have another scope running a QHY 268M and on this camera I keep using USB3 cables with no connectivity problems. The cable goes to a Pegasus UPBv2 and then a second cable routed through the mount and connected to a computer at the base of the pier. It has one fewer hop than the Mach2, which may make a difference, or the camera connector fits more snugly and doesn’t loose contact in the cold.

Roland,

I have been imaging upstate NY through the recent sun-zero cold weather. The lowest temperature was -12F. Both the AP Mach2 and 1100 kept humming along with no issues. No equipment failed. 

In the Fall I started having intermittent connection problems with USB3 cables and the ZWO ASI6200 connector (cable run goes to a Pegasus UPBv2 and the Mach2 internal cable, before going to a computer next to the mount). I tried several cables but they all had this same pattern of disconnecting intermittently. I switched to a USB2 cable and problem solved - no more connection problems. 

This setup has held up well down to -12F with no equipment connectivity issues.

Although i missed out on getting images tonight for a color version of this. I decided to post what I have from a session on the weekend.
It's labeled the Old Man and Eagle contemplating a Brain Coral.
I decided to orient and crop the image in an unusual way in order to present a different picture of this oft-imaged object.

Re: APPM changing gain on ZWO ASI2600MM Pro #APCC #Mach2GTO

David,
Check to make sure that the ZWO ASCOM driver is set to whatever gain you want it at.  If SGP doesn't define a gain then the ASCOM driver will default to whatever you have it set at.

APPM does not purposely change gain. It could be SGPro is using a default value.

I've been using a ZWO ASI2600MM for some time with no issues except that I was noticing that the gain would
mysteriously change from 100 to 0. It was very frustrating, because I would often find that I was taking doing
a sequence at a gain of 0 when I know I had previously set the camera gain to 100 and not changed it. I
finally figured out that APPM appears to be doing this. I am using Sequence Generator Pro as my "camera"
in APPM, with the ASI2600 as the camera in SGP, and I checked the gain in SGP before and after, and APPM
did indeed change the gain. I can't find any setting in APPM that concerns gain, but maybe I'm missing
something. I don't remember this happening with other ZWO cameras when using them through SGP in
APPM. Thanks.

I guess I’ll wait for Ray to chime in before installing 6.6. This reminds me of 6.5 when Ray recommended that
we wait for 6.5sp1.

Re: [ap-ug] Deep Freeze imaging tonight

Well, it was a short session. First I lost the camera USB connection, then the other USB cables stopped working. Tried two new cables but they worked for only 10 minutes. Only one cable is still working and I have no idea why cables don't work in the cold.  Are the plastic connectors shrinking and losing contact?

Hello Astronuts,

I have been imaging on and off for the last week or so in temperatures close to 0F. Tonight it is slated to drop down further to -12F (-25C). It's already at -18C, so this should be a great test to see what dies first - mount, laptop, or camera. Right now the Mach2 mount is happily slewing at 1800x with no muss, no muss.
The QSI 683 camera fan is sounding a bit strange, like it's being strangled. In the past the filter wheel froze up because the rubber O-ring shrunk and the motor shaft wasn't making contact any more.
The 10" Mak is waiting for photons to arrive, 'twill be interesting. Let cha all know how it went later tonight.

If it's working, don't mess with it. Re-greasing is not needed unless you run it every night for the next 5 years.

I swapped the scope/CCD with another system, both systems worked fine. So it is not clear to me what the problem was, whether it was mount or mount+scope/ccd, or something else.

Brian,

Did you see anything wrong in the log?

Roland,

How often should mach1 be cleaned/re-geased/re-meshed?

The spikes were between dithers, so dither should not be the problem.
One of my friends said he had similar issue on his AP mount, and cleaning/re-gease the gear fixed the issue. Do you think mine looks the same?

Each pixel is ~4" so spike is ~10".
 
What could be the problem? There is no noticeable backlash on RA/DEC. RA/DEC are well balanced. Do I need to re-mesch RA, or something is wrong with gearbox?
