I am resurrecting DL5 on a new computer, and should be able to upgrade to 518. Where can I find the relevant .exe? Many thanks

I have updated to firmware version 41, and when rebooting I am now recieving the following message: "The system Bios has detected unsuccessful post attempt(s). Possible causes include recent changes to BIOS performance options or recent hardware changes. Press 'Y' to enter BIOS Setup or press 'N' to cancel and attempt to boot with previous settings." I have not changed the Bios. I choose N and reboot, and everything seems to work fine. Have you seen this behaviour?

I am using TheSky64 camera controller with and AC455. I have recently successfully updated to Firmware ver. 41. In TheSky64, when setting up the camera I choose DL imaging for the camera, and then go to settings. In settings I have the ability to choose high gain or low gain. The problem is that if I choose either high gain or low gain, the camera behaves the same, and is in high gain mode. This behavior is unchanged from all firmware and DLAPI versions. When choosing low or high... Read more

Doug/Colin, I have been using my STXL-11002M and self-guiding filter wheel with a CDK-17 and Hedrick focuser successfully for several years. I decided to upgrade to the IRF90 rotating focuser and have run into the dreaded fan vibration issue. If I disable the fan in Maxim camera setup, the stars on 4sec exposures are round. If I enable the fan, the stars become elongated and sometimes display as dumbells. After some research here, I found info about swapping the original fan with a Noctua... Read more

Hi , I have a STC7 serial number STC7M-21010703. I bought it about a month ago, NOS, filters are still sealed in the box. Sat on my shelf since I got it and last week started using it inside to check how it works. Plan is to use it in NINA. Bought a Mini PC and installed all the software needed. At first I did upgrade the firmware to 11, installed was 4. It went well as far as I can see. Then plugged it in NINA and perform a few test, one of which was cooling, first time the graph showed...

Our filter wheel stopped moving and we found that the main carousel bearing had worn out. There was aluminum powder and the retaining clip fell off. We would like to purchase a replacement bearing or find out the correct size and characteristics so we can find a new one. We think the filter wheel was unbalanced as the person that installed the filters put them all on the same side and left the empty slots together. We will rebalance the wheel after we get the new bearing. Is this possible... Read more

Hi, I have a AFW-12-50RT connected via the USB-FW using The SkyX to connect to the system. When connecting the filter wheel, it comes up as Ready, the drop-down for the filter wheel contains no options to change the filter. Clicking on the Filter Names Setup reports that that it has zero (0) filters, yet the correct FW is selected and COM port. This has happened previously and when power-cycling it has removed the error, but now it comes up every time. Connecting with Maxim DL and... Read more

As you can see, images I took last evening (and at some other times) show these horizontal streaks. What gives? Image was taken through H-alpha filter, 120 sec exposure, through PlaneWave CDK-17. Images through SII and OIII show a different pattern of horizontal streaks. Flats don't show the streaking, but darks and biases show some horizontal streaking. Thanks!
