Andrew created a new topic ' Issues I had last night after v4.5.6, probable cause?' in the forum. 9 hours 24 minutes ago

  1. Solved rotation is 40° behind actual frame rotation. Already reported here
  2. Canon live view stream used to work with 5x zoom enabled
  3. Odd guiding behavior: made large corrections in a sinusoidal pattern with a period of only a couple minutes. (disabled backlash corrections just in case, didn't help. It stabilized itself once on it's own. I had frames come in with stars tracing ovals.
  4. If image are taken while LiveView is enabled, things go horribly awry.
  • Shutter action is delayed until after I hit live view button
  • Captured image comes in blank
  • Camera is stuck trying to write file somewhere, (also an issue with aborted actions)
  • Power cycling camera to clear write buffer causes havoc. Must reboot to reconnect, and other USB device connections interrupted (RPi3)

Andrew replied to the topic 'KStars 2.7.6 is release' in the forum. 9 hours 47 minutes ago

I noticed now that solved rotation figure does not match the solved frame displayed on the sky. The solved coordinate Rot is 40° smaller than the white frame displayed. For example, the Rot in Solution coordinates says 89.9° (With a simulated CCD beginning with Rot of 0°, that's already odd). And the white solved frame displayed does match the the image capture. I determined this by rotating an FOV symbol to match that.
This made it very difficult for me to determine my proper orientation last night.

I had a failed meridian flip. It may have been set to >0 though.

Is there some kind of statistical analysis in place to prevent outliers from triggering excessive corrections? For example If a corrupted image frame were to come in, as can occur in my experience with ASI120. How would the algorithm respond to that?

It's been a few days so that should be the case.

Andrew created a new topic ' Astroberry Focuser with Adafruit Motor HAT' in the forum. 3 days ago

I'm starting this topic up as Kaczorek mentioned it would be prudent to start a seperate thread on this topic, with a shout-out to Christian for his modifications.
Regarding the development of an Adafruit version of the Astroberry autofocus driver. The Adafruit motor controller HAT appears to be an excellent alternative to the PiFace. Whereas the PiFace required 2 integrated boards to control stepper motors and is no longer produced. The Adafruit is an all in one solution at a quarter of the price and is still being manufactured. It also just came back in stock. IMHO an ideal DIY autofocus platform.

I watched this presentation earlier last week, Very interesting stuff. If I recall they mention a few times that they would be happy to share this for further development, and I think the host might have mentioned Jasem, and Kstars INDI directly.

I had a chance to ask him why he finds it necessary to spend the time focusing on a bright star. And the reason was he is imaging with very fine, 3nm narrow band filters.

When I restart the INDI server, the toggles for using RA and DE backlash settings reset to disabled in EQMod Driver. They do not appear to get saved with the configuration.

Using ASI 120MM. Changes made to this driver are not getting implemented after restarting kstars. For example I change Gain from 20 to 40 and Telescope form Primary to Guide, then save. But the changes are forgotten after closing KStars.

I would just rotate the camera manually and do a new solve until the rotation comes close to what I'm looking for.

Andrew created a new topic ' Advanced Framing. Musings.' in the forum. 1 week ago

I was considering an idea to assist with framing images. I propose a new form of symbol, similar to an FOV symbol, it too should represent the field of view of a camera. Give this symbol the ability to be placed at any location in the sky and set a rotation. To make use of it, I propose making it an object that can be slewed to and tracked via the right-click menu. Also it's proper location could be copyable into EKos scheduler via a single button. And the set rotation could be compared to astrometry results until they match to the user's satisfaction.

This idea occurred to me while trying to frame parts of the Markarian Chain by roughly aligning the FOV symbol and changing its rotation. Would anybody else find this useful?

I encountered this. It appears to trace wide arcs and then the pointer jumped 180°. I thought it was cone error preventing me from pointing at NPC, but I recalibrated that and I wasn't that far off.

It appears that the PiFace Relay+ is no longer manufactured. It is only available from 3rd party distributors, presumably there is a limited supply now.

Andrew replied to the topic 'My DIY Focuser with AstroBerry' in the forum. 2 weeks ago

Thank you Christian. I am interested in assembling a remote focuser controlled by the Pi, having had some success with a remote controlled one I designed mostly with 3D printed parts and off the shelf controller boards.
At this time I don't have any servo controller boards for the Pi. Adafruit appeared to be one component and less expensive, vs the PiFace Relay Plus And additional PiFace Motor Extra. I should probably go with PiFace if this hardware is already supported by your driver as I do not have any developer experience.

Will this work with the Adafruit motor controller HAT?
