Once you install the Thunderbolt adapter, it will appear in the device manager as an Ethernet port. You will still need to configure that port as...
Yes the AC455 has been working flawlessly with my Eagle via the Thunderbolt adapter.
Yes, something was definitely up with the shutter. Those are not blooms. You can see the effects of seeing on the trails - they jiggle around...
Yeah definitely use the latest firmware and software.
Let's rule out the IR preflash diodes. You can't see them with your eye, of course, because you can't see IR. But a camera can. Open the...
I'm actually not certain that's blooming. I'd like to see a FITS image. Check to see if the shutter is working correctly.
A light leak could do this, but it would have to be in front of the shutter. Otherwise it would show up in dark frames. The RBI mitigation...
Can you upload a dark frame, same exposure conditions?
You can get weird shadows if there are no optics on the camera. At least put a piece of white printer paper in front of the aperture, and shoot...
What optics were in front of the camera, if any?
How are you illuminating the camera? There's a shadow in the right, and a bright diagonal line at the top.
It's pretty much impossible to get a diagonal line due to a problem with a CCD sensor. They read out on a grid after all. Watch the operation...
That looks optical. Check the filter wheel and shutter.
Had a couple of hours of clear skies last night, so I grabbed a quick image of M42. Aluma AC455, Ceravolo 300 Astrograph configured for f/4.9,...
Both Colin and I were long-time friends of Dave Lane, who passed away last year. He was the author of a very nice planetarium program called...
You should have a look at our Backfocus Calculator spreadsheet: https://diffractionlimited.com/downloads/BackfocusCalculator.xlsx
That is quite old. There's a simple mod we can do to improve that behavior. If you would like to return it for service, please fill out this...
Years ago I made a minor improvement to the DC restoration circuit in the STX to reduce this phenomenon. If it's old enough it might not have the...
No doubt the warning stickers were removed when the camera was installed. It's also in the user manual. This has always been a warning on all...
That looks like some kind of hardware failure - probably a problem with an internal switching power supply. Unfortunately we no longer have the...
