EAF position lost on power fail

My EAF loses its position information if power fails for any reason. So I presume that the position value is not saved in a non-volatile RAM. Also, I cannot find any way to enter a known position. I can only set the current position to zero. This aggravates the above problem because I always record ...

Re: dealing with reflections and diffraction with ASI1600MM

I realize that the ASI1600GT uses the same sensor. The question posed is really one of how the optical path or filter setup has changed. If I were making such a significant enhancement to the ASI1600MM Pro, I would have addressed the well known and highly undesirable reflection problem. Richard Tabb...

Re: dealing with reflections and diffraction with ASI1600MM

In my experience, the ASI1600MM suffers from bright star reflections between the sensor cover glass and the color filter in use. My experiments reveal that the protect window glass is not involved in the reflection issues (although the 2 mm thickness of that glass does cause undesirable refraction a...

Re: ASI1600MM Pro Problems

Here is the current status: The camera will not operate reliably on my PC when connected with USB 2.0. I installed a USB 3.0 PCIE card yesterday, connected the camera to it, and tested the system all night using the ASCOM drivers. It performed with 100% reliability, and the EFW operated flawlessly c...

Re: ASI1600MM Pro Problems

The cables I'm using are tried and true, but yes, I tried another. No help. Regarding ASICAP, the camera is detected (as long as it hasn't disconnected from USB), and I can select it, but I have no idea how to operate it with that program since it seems oriented toward video. All I ever see is a com...

ASI1600MM Pro Problems

My new ASI1600MM Pro is unable to operate reliably wit TheSky X, connected either via the X2 plug-ins or the ASCOM drivers. Many problems, including receive time-out errors (USB bandwidth set to 40), random USB disconnects, and simply no camera response. TheSky X is latest daily build, and I'm runni...

Re: ASI1600 or ASI183

I cannot recommend a further focal length reduction of your f/5.8 telescope. You will otherwise have a very frustrating time with vignetting, especially if you intend to use a filter wheel. Focus also becomes super-critical and hard to hold. I have never had a good result when attempting this level ...
