Re: [ap-ug] Deep Freeze imaging tonight Eric Weiner #84474 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. Eric

Re: [ap-ug] Deep Freeze imaging tonight Roland Christen #84473 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.

the Old man, Eagle and Brain Coral Roland Christen #84471 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. https://www.astrobin.com/full/gl1oko/0/ Have fun finding them Rolando -- Roland Christen Astro-Physics

Re: APPM changing gain on ZWO ASI2600MM Pro #APCC #Mach2GTO Joel Short #84465 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. joel

Re: APPM changing gain on ZWO ASI2600MM Pro #APCC #Mach2GTO Ray Gralak #84464 APPM does not purposely change gain. It could be SGPro is using a default value. -Ray toggle quoted messageShow quoted text -----Original Message----- From: main@ap-gto.groups.io [mailto:main@ap-gto.groups.io] On Behalf Of David Johnson Sent: Tuesday, January 25, 2022 4:19 PM To: main@ap-gto.groups.io Subject: [ap-gto] APPM changing gain on ZWO ASI2600MM Pro #APCC #Mach2GTO 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.

Re: [ap-ug] Deep Freeze imaging tonight Roland Christen #84461 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?
