Asiair say my camera and EAF has changed at every shut down.

Kevin_A

Anyone have this issue? Both my main camera and EAF work fine during acquisition but it is annoying getting 2 black boxes pop up saying that my devices have changed and that I need to unplug and plug them back in. It happens everytime I shut down asiair. Is there a fix?

Kevin_A

Fixed… unplugged the usb cables while running asiair and plugged them back in and turned both devices on againin their menus… no messages during shutdown.

Kevin_A If this happens again, please submit the log to us, thank you

Kevin_A

PMTeam@ZWO will a log be created even if I am just turning on my equipment, testing the devices, slewing the mount, running the eaf and doing calibration files like flats… but not guiding? Or do I need to be guiding? It is cloudly here.

Kevin_A

nothing shows up in the log. The equipment runs fine other than it just say my devices have changed at shutdown and to unplug and plug back in.

Here are the screen shots. I have the eaf plugged into the camera and tried replacing the usb3 cable with the same messages.

Kevin, I see you are powering the camera (and probably the EAF through the camera's hub?) from the ASIAIR 12V DC outlet?

ASIAIR probably forgot to disconnect the camera before shutting off that DC outlet.

If you were to power the camera directly (cleaner power for the camera anyway) from a DC source instead of through the ASIAIR, I wouldn't be surprised that the nuisance messages go away.

w7ay yes, you are correct, I was hoping to keep my scope wiring setups very simple and clean. Right now i am powering asiair and the mount separately and was hoping to avoid another dangling power cable. I believe you are 100% correct about asiair not turning off the camera before the port. Maybe ZWO can fix this in a firmware update.

Kevin, this is how I keep everything clean (this picture shows the same OTA as yours, when I need more FOV than my FSQ-85):

One of the nice things about a (normal) strain wave geared mount is that third-axis is of no concern, which makes dual saddle mounts (I used a 10 mm thick plate) easy to implement.

BTW, notice that the Askar clamshell can be reversed, so that the dovetail plate can be shorter, and more stable.

The ASIAIR is mounted inside a waterproof box at the base of the Willaim Optics tri-pier that I leave outdoors (including the RST-135). A single power cable reaches the dual saddle's power hub, and a sibgle USB cable from the box is connected to a USB hub on the saddle plate.

I have a couple of configurations for the guide scope. You see a Askar 180mm here, but I have also adapted a Borg 55FL objective on the same Askar 180 body to get a longer guide focal length (250 mm).

Here is a "top view" of the saddle plate:

To mount the OTA on a plate, I did have to make my own adapter plate for the EAF so that the EAF does not stick below the dovetail plate of the main OTA (ZWO again wasn't thinking when they made that plate so the EAF sticks below the declination plate):

w7ay i keep 4 asiair setups that i just drop on for all ranges… 15-30, 135, 300 and 644mm. The fortunate thing is that even with these error messages the acquisition is flawless, so more of just an annoyance than issue.

This is my widest setup, a Sigma 135 mm ART lens and the full-frame ASI6200MC:

The mezzanine plate is just to hold the EAF and the Starizona EOS filter drawer, a USB hub (for camera and EAF), and a rack handle. This mezzanine plate drops into the Losmandy saddle of the same dual saddle plate.

Only thing wider is my all-sky camera, which is mounted near the roof of the house, and not on the RST-135 :-).

w7ay I just put together my Tamron SP 15-30mm f2.8. It is fabulous for little coma and just waiting for clear skies now. I used a cradle from a svbony sv503 80mm scope as it fits perfectly on the 2600 and lens. I plan on doing milkyway core images soon. As you can see I need dew heaters on everything where I live.

Kevin_A It is fabulous for little coma

Even the Sigma ART lens (f/1.8 wide open) needed to be stopped down to f/2.9 to get reasonable stars (using step-down rings).

This is the Sigma ART with the ASI6200MC set to APS frame size, not full frame size

Corners' point spread function already quite a bit worse than center at APS-C. Full frame cropped to a square FOV is an acceptable compromise.

w7ay the Tamron is real nice at f2.8 but heavy. Fluorine coated lens too. I tried a few Sigma Art lenses but unfortunately I got bad copies so I took them back. Tried the Art 40 and was not impressed. My Sigma S 70-200 is great for day use but horrible for astro. My Rokinon is nice after 3 copies and does well at F2.4 but best at f2.8. They all work great on my Nikon Z7 fullframe too.

The Sigma that I have is not too bad. Here is a full frame ASI6200MC (with narrowband filter) of the Lobster Claw region (scaled down by 2x but not cropped).

I just did a quick check of the sub-frames with Astro Pixel Processor and get (flat fielded) min-max FWHM variances like this:

I am just used to my FSQ-85, where the FWHM is constant over an entire APS-C frame to the second decimal place :-).
