I'm using a 2015 MacBook Pro 13" as my imaging laptop. No issues here. My setup and images I've taken are all at my website linked below. I've had no issues doing high frame rate planetary or DSO imaging. But my frames are around 32mb which transfer instantly over USB3.

Wow, that's awesome, I'm going to try that.


Unfortunately I don’t. I don’t typically have logging turned on. If it’s not a performance hit, I’ll start using it regularly in case anything crops up.


During my last imaging session I ran into some issues with the Scheduler. On previous nights I had imaged two filters, and the scheduler performed properly taking the photos, and switching filters, with the sequence set to repeat all night until astronomical twilight.

Realizing I wanted to do one more filter the following night, I created a new schedule for the same object, but set the sequence to be 1 frame of 1 filter for 180s, then I set the schedule to repeat it all night until astronomical twilight. It didn’t like this, and immediately shut down the schedule and parked the scope after performing alignment, focus, guiding, and imaging 1 frame. I then changed the sequence to 240 subs of 180s on the single filter, and tried again. This also aborted and parked the scope altering alignment, focus, guiding, but no images this time. I finally changed the sequence to have multiple filters, but just set so many subs that it would never switch to filter two, and this worked as expected.

There might be an issue when using only one filter in a sequence, or 1 frame of 1 filter on repeat until twilight.


Andrew Burwell created a new topic ' Suggestions for Focus module' in the forum. 2 weeks ago

Since 3.0, I’ve been imaging with quite a few sequences, and have seen some repeated issues crop up with focusing.

I’ve seen the Focuser system automatically select stars in the corners multiple times. This is certainly a poor choice if you have any off axis issues like tilt, or if you have coma in the corners that needs to be cropped out. It should try to pick stars within a center circle area of the image.

Secondly It can tend to grab rather large stars. If you’re imaging with an RC and you have diffraction spikes, this creates some issues on the focusing module knowing what is the best FWHM for that star. Alternatively I’ve seen it pick extremely small 1-2 pixel stars, then easily lose the star as the focusing routine starts. Seems the best option is to pick stars between an FWHM of 2-6 and anything outside of that size should be discarded. Of course, this might make things challenging if someone starts the focus routine out of focus. So maybe there are several steps where it picks any star first regardless of FWHM to try to get it in rough focus first, then it moves on to a star with an FWHM of 2-6 to ensure focus is accurate. This to me would be way more reliable.

I finally got the CGX. I’ve not tried the side USB port, but have been using the one in the hand controller. It works great using the Celestron driver. Even the park function works, which never did on my AVX.


Andrew Burwell replied to the topic 'Selecting dark for focus or alignment.' in the forum. 3 weeks ago

I noticed that between sessions (after taking darks for guiding, quitting Ekos, and restarting it) that it asks to take darks again. Is this normal behavior? I would prefer it just keep the darks for all sessions and not ask anymore unless an exposure setting gets changed.

It would be really handy if the settings area for the dark library could have a feature to capture all darks for guiding, plate solving, and focus. Maybe even a way to build in a few darks for calibration against lights when you're capturing objects.


Andrew Burwell replied to the topic 'How does the darks in Ekos work?' in the forum. 3 weeks ago

The darks it takes for alignment, guiding, focus, etc are only a single dark to be subtracted from the lights it's taking during those processes. It does them only once for this purpose and saves them in the dark library. This is different from the darks you will capture as part of the calibration process for your light frames of objects you image.
