I've won somewhat more accurate AC4040M panel flats by inserting a 5-second delay between each flat exposure. This did require slightly modifying...
For my CCD camera, I needed 25 flats at 50% ADU level. Four minutes and done. But to equal that total ADU count with the AC4040M at 10% level,...

I have uploaded 3 example files. They may be downloaded directly from ericdose.com/SBIG/ MP_2356-0001-GG495.fts : ACP Subframe 0.95, severe...
When running ACP #Subframe directives, I get serious banding in my AC4040M FITS images. The banding immediately goes away when I remove the...
All ACP.
Thanks. The repeater is a Tripp-Lite, very unlikely to be a crappy one, but it is USB powered. And I've used only industrial StarTech USB hubs in...
Last night's log is attached--it shows five rogue disconnects, most of which I happened to witness (remotely). They all happened during rapid...
It is not Selective Suspend, it is not Power Management. Checked long ago, and regularly since. My first USB problem is that my mount is too...
So far (though I'm fighting a camera-disconnect problem when taking images at very high cadence, as with flats), my flats have indeed been...
Thanks, William, I'll certainly keep this in mind. Probably I'll first test the reproducibility of a series of flat exposures shorter than I'll...
OK, I have my first working flat images on the new system. OTA: PlaneWave CDK 20 f/6.8, no reducer. Flat panel = Alnitak Flat-Man 24. Camera =...
All good to know. Thanks, Colin. If taking flats much shorter than 1-2 seconds turns out to be advantageous, I'll report back here.
Perhaps. A good idea. In fact, in High Gain I may as well take flats shorter than 1 second to keep the flat panel brighter. To that end: do you...
On my new AC4040 (DLAPI 2.7.1.0, firmware 14), I cannot set the Stacking Sub-exposure in DL Config to 1 second. The Aluma AC manual (v.1.06, page...
OK, you were right, it was my own blunder--my ASCOM was back at 6.4 SP1. After updating ASCOM to 6.6 SP1, all seems well, so let's call this...
Hi, Colin, The scope PC runs Win 10 Pro x64, ASCOM etc is up to date, and the pc has no groups and almost never runs Admin privilege (I will...
I just tried twice to install the DL ASCOM drivers on my Win 10 Pro scope PC, and got an error "Unable to register the DLL/OCX". Rebooting the PC...
Closing the shutter after significant idle time is a good idea (I don't know yet whether mine does that)--but it probably doesn't solve the...
On (quite successfully) bench-testing my new AC4040M (firmware rev 14) before first installation on scope, I noticed that the camera's shutter is...
