I checked if the lens had dew but it was fine. I changed the focal length and also tried entering "0" so it would decide itself. All I could think about in the end is that ASIair was a bit corrupted somehow. So today I have reset to factory and then updated. The only problem now is I probably have to wait five or six weeks for a clear night.

Good morning, Last night I actually had a clear night for the first time in weeks. I got out my new ASI 585mc camera and decided to take pics of Jupiter on my ED-120 refractor. I hadnt connected the ASI 585mc to the refractor before, I had it on my celestron C8 and it worked perfectly. But last night I could not get the ASIair plus to polar align, it would not plate solve. I thought maybe my focusing was out so I used the bahtenov mask to obtain perfect focus. It found 43 stars but I still could not polar align & plate solve. I tried powering off and starting again and still the same. The ASIair has version 1.91 (9.97) running which has been fine up till now. So I am wondering if the problem was connecting the ASI585mc to the refractor could be the problem or the ASIair? In the end I tried ignoring the polar alignment, and tried to goto Jupiter. It missed Jupiter but found 212 stars but still wouldnt plate solve. So I spent 3 hours and didnt do anything. Has anyone else had this type of problem?

Hi, Can I somehow use my DSLR clip filters with a ZWO astro camera. Maybe some kind of filter draw for clip filters. This will save buying them again for the astro camera.

Up to now I never have had to set a home position. I always start off with the mount pointing north, and the 52 degrees latitude set up but I have never said return to a home position in the past and never had a problem. I dont even know how to set a home position in ASIAIR. But maybe I should look into that. Also when I polar aligned it, it should know where it is and be able to go to a target?

Sorry guys I am leading you on a wild goose chase. I just realised I put the time into my synscan in dd-mm-yy format, what a pillock. The only reason I was trying the handset was because my ASIAIR was taking me to the wrong place after polar alignment. So I am back to my original fault now. Anyone know what could be wrong with my ASIAIR, which has been working good up to now. So I will explain again, using my ASIAIR I polar align perfectly. Then I enter my plan, Flaming star nebula C31, 300 seconds 40 exposures. Now normally when I run the plan it drives perfecly to the object then plate solves and starts the exposures. But this time it points down at my garage wall, nowhere near C31. So I send it to Polaris, it drives there fine but then says it cannot plate solve, I dont know why because it previously did it. So then I sent it to Capella which was pretty close to C31, and again it pointed down at the garage wall. This is the second outing it has done this. The power supply was fine. I even updated the ASIAIR to the latest firmware and it still did the same. Any Ideas?

Screws on the left. Its always been fine before.

I turned off the power, and started from scratch, like I always used to do before having the ASIAIR.

Last time I had a clear night, I polar aligned using my ASIAIR then I put a plan in for C31 Flaming star neb. When it should have slewed to C31, it just aimed at my garage wall, miles from C31. I couldnt get it right on the night, in the end I assumed my power bank was low and so the mount couldnyt slew right. So tonight I did the same again, good polar alignment still using my ASIAIR, and again the mount slewed to the wrong place. Power bank was fine. I updated ASIAIR, still the same. So I disconnected the asiair, and reset the mount and run it from the synscan. Polar aligned fine, the I chose singe star alignment and chose Capella in the east., and the mount slewed to the west. So I reset and started again, and again it to took me to the wrong part of the sky. Never had this problem before. Can anyone shed some light on what might be wrong?

I have recently bought an ASIAIR Plus. A few nights ago I put an Ha filter in my DSLR. To polar align I had to make the ISO 6400 so the ASIAIR could see the stars and it was taking 10 second shots. Then I changed my ISO to 1600 on the DSLR and the shot length to 300 seconds on my plan, then It started to slew to my target which was C31. But it could not plate solve because it couldnt see the stars on ISO 1600. How can I plate solve on ISO 6400 but then change the ISO to 1600 for the longer exposures. Each time I change my plan on the ASIAIR it wants to first plate solve the target. Am I not understanding something here?

Thank you all for the replies and suggestions. I think I have a much better understanding now. I was using too many cables. I will just await a clear sky and give it another go. Thank you all again for the time you have spent sorting my problem out. Chris

My hand controller does'nt have a USB socket. It has the ST-4 connecter and the one that goes to the mount. I use the EQDIR cable to connect the pc to the synscan controller, I thought I needed that for APT? If I dont connect the EQDIR cable APT wont recognise my mount. I have to put the hand controller in the PC Mode or, again, APT doesnt recognise my mount. I connect my guide camera to the mount with the ST-4 cable then the USB3 cable to the PC. So I polar and star align using the Synscan, then I add the extra cables 1), The DSLR to the pc for APT to recgonise the camera. 2) The EQDIR from hand controller to the pc. Then I launch the PHD2 and APT programs. I connect the guide camera to PHD2, and then I connect the ON Camera option on PHD2. I then start it looping, let it find stars to guide on. Then I click on the guiding button, and it tries to calibrate. I get an error saying one axis isnt working and the it might not guide properly. The Only way I can get it to calibrate is by disconnecting EQDIR cable from the hand controller. I thought all this was needed? I do have the Ascom platform installed and my PC operating system is windows. I think I have too many cables connected by the sound of things.

I am only using APT so I can dither my pictures, so I dont know if I need the cables as I have them. I like to use the synscan for the goto function. But I was under the impression I had to connect the cable from the Synscan to the PC, so APT could work?

I cant understand why everyone else just seems to connect and work. I followed Trevor Jones on AstroBackyard. He conects the guide camera to the mount, using the "On camera" setting, and everything works fine. I have three USB sockets on the laptop, so I connected as Trevor Jones did, using these three USB's. He polar & star aligns from the synscan, so I do that, then he plugs in the extra connections for the guiding and APT. So I did that. Then the calibrating on PHD2 says one axis isnt responding, and wont calibrate, and it wont calibrate until I unplug the cable from APT which goes into the Syscan hand controller.

I have the Guide cam connected to the PC and also to the mount. My DSLR connected to the PC, and the Synscan connects to the PC.

I find I cannot use APT and PHD2 together. Both work independently, but together my PHD2 wont calibrate, it says there is something wrong with one axis or the cables. Then the guiding doesnt work. If I disconnect APT and the cable to the Synscan controller on my HEQ5 Pro mount, the guiding calibrates and guides ok. APT says its connected to PHD2 ok. Has anyone had this problem? Could it just be a setting somewhere?
