Jon,
Yes I had same ideas.
When auto debayer is off the focuser seems to use averaged grayscale histogram with acceptable results.
BlurXT sure helps.

Thanks!

Hello,
I asked about this at a Cloudy Night forum and got some useful answers.
I am wondering if this could be improved some more...

Problem: Red channel is focused perfectly, Green and Blue are out of focus.
That's when FITS Auto Debayer is turned ON.
I believe, in this case Ekos is using the Red channel to focus on.

When Auto Debayer is turned OFF, the focusing is better but the Red channel is slightly out of focus.
Much better but not perfect.
I believe, in this case Ekos is using the average grey level image to focus on.

Is there anything which currently could be done to focus all channels more equally?

Thanks!

Example. Debayer is ON. Antlia ALP-T (L-Ultimate is similar).
Red vs Blue.

Wow. I didn't expect that logging might cause any issues...
I never noticed any interference from logging but just turned off the verbose logging for my new session.

Yes, this feature is already there.
In fact, I am using it for the first time tonight.
Set to refocus every 60 min. Works well!

That's because it takes some time to download/save an image?

After exactly one month since I shipped the camera to ZWO USA service center I got it back today.
The camera seems to be working.
No feedback on what was the problem and how it was fixed was provided.
Shipping both ways was free.
All in all not too bad.

Can't help you with the airport situation but thank you for the tip on the Mele quieter mini pc!

When I travel with my AZ-GTi and DSLR (no airports), I only use two or sometimes four batteries.
TalentCell 12V 3000mAh to power AZ-GTi (lasts for a few nights).
TalentCell 12V 6000mAh to power DSLR (lasts for a few nights). If I use this battery to power RPI4 as well then it lasts for just one night.
I use another 12V 3000mAh for a dew heater if needed (one night).
I use another 12V 3000mAh for a monitor if needed (1-2 nights).

Hello,
I set up a simulator profile mimicking my 135mm wide field setup.
135mm and 6000x4000 frame.
It kind of works but not quite.
I hardly get any stars. There are stars but they are very faint (almost invisible) even with a long exposure.
Online solver works on them but none of the internal solvers work (not enough stars).
Guider works (smaller frame size) but not always - not enough stars.

Are there any settings in INDI Control Panel I can adjust to increase the simulated star intensity?
I am using gain 80. Tried 100 - no difference.

Thanks!

Optical Trains work OK for me.
But I did have a problem trying to set up a DSLR Lens - it didn't worked right for me so I ended up setting it as refractor (which worked fine).

I always use the auto-park option. Works fine.
Goes to Park after the PA procedure is completed and Stop is pressed.

NMAC,
That was it - thanks much!

Looks like I set it to 6000x4000 during the initial setup and then tried to change via INDI control panel (which didn't work).
Reset DSLR and setting to 6016x4016 fixed things.
Thanks!

Hello,
While my ASI2600 is being repaired by ZWO I am trying to use my Nikon D5500 for imaging.

When I shoot just with the camera (no computer control) or with Ekos set to NEF (Raw) and Native, I get 6016x4016 frames.
Interestingly, Pixinsight and Affinity report 6016x4016.
APP reports 6016x4016 6000x4000.
Photoshop and ACDSee report 6000x4000.

When I switch Ekos to NEF (Raw) and FITS, Ekos starts to shoot 6000x4000.
All software report 6000x4000.
I do not like that since I have a library of Dark/Bias masters shot at 6016x4016 and most often use D5500 without Ekos.

I want to stick with 6016x4016 which means NEF (Raw) and Native.

However, in this mode the preview shown in FITS viewer is converted to 8-bit and overexposed while the actual (saved NEF) image is 14-bit and not overexposed.

With Ekos set to NEF (Raw) and FITS the preview is fine but the frame size is not right.

Am I doing something not right or is it just the way it is?

Thanks!

Today I prepared a new SD card with the latest Stellarmate 64-bit (basically a copy of the card used in my first post)
and set it up to use with an AZ-GTi mount and a Nikon D5500 DSLR.
Used the same USB cable to the camera.

Now I am getting 8 sec download times with NEF and less than 2 sec with FITS.
Much better - I like this!
Don't understand why it improved...

Hello,
Back in December 2018 I started using Stellarmate/KStars/Ekos with a DSLR (D5300) as an imaging camera.
I just checked my archives - I was shooting RAW Native (NEF) and saving to both client and camera's SD card.
Image download time was about 8 sec.

Soon after I switched to an OSC camera.

My OSC died recently (sending it for repairs to ZWO tomorrow).

So, I tried to use a DSLR as an imaging camera tonight (just a test with simulators).
Now it's D5500 (about the same as D5300).

When I use RAW Native (NEF), the image download time is close to 20 sec now!
A bit too long...

When I use FITS, the image download time is down to 8 sec.

I am OK with using FITS but why such a big difference?
Why it was so much faster four years ago?

Thanks!
