I'm jealous of your dome, and location! What a sight.

Here's my latest setup with two different imaging scopes. The Edge11 with ASI6200, and the Esprit 100 with ASI2600.

Located conveniently in my back yard.

Solved! Turns out the offset on my darks and flats and lights did not match. Had no idea offset made this strange outcome. The new integrated image of the Wizard Nebula in HA shot with Chroma 3nm filter.

Posting this here in case someone has experienced this.


I'm facing some calibration issues that I just don't understand. This was first light for me with this camera. I have integrated and processed more than a hundred images on mono and color cameras before this. I'm wondering if binning or metadata is incorrect causing the programs to integrate them wrong. Or maybe I missed something crucial when capturing that makes the frames not compatible.

Here's what I shot:
Lights HA 120s Gain 100 offset 50 Bin2x2
Darks 120s Gain 100 offset 50 Bin2x2
Bias .2s Gain 100 offset 50 Bin2x2
Flats HA 25k 1.39s ADU Gain 100 offset 50 Bin2x2
FlatDarks HA1.39s ADU Gain 100 offset 50 Bin2x2

This is my calibrated result every time. I've tried with bias, and flat darks, and both. I've tried flat ADU values ranging from 2k to 25k resulting in no difference. I've processed with Pixinsight, and with Astro Pixel Processor. I'm wondering if the Binning has something to do with things being read incorrectly, as that's the only difference I'm seeing compared to other users.

Here's a link to 1 frame of each of the above in case someone can find a discrepancy in the exposures, gain, or metadata leading to the issue.

Oftentimes, the preference windows open behind EKOS or KStars, and you need to move them out of the way to see it.

I would assume, that whatever developments happen here for the 2" ESATTO also will work for the 3" and 4" versions as they only to appear different in size. Possibly considering a 4" for an FSQ 106.

Andrew Burwell replied to the topic 'SQM readout on the Weather/Dome tab of EKOS' in the forum. 4 weeks ago

I use an MBox, which sends humidity, barometric pressure and temperature to my mount for accurate pointing. So I can't choose both there. I have SQM set in "AUX". I also have a Pegasus UPBv2, which also shows temperature and humidity.

Would like to see the SQM readout on the Dome/Weather tab. There's plenty of room, and this is an ideal place for it so that you don't have to open the INDI control panel to see it.

Thanks!

I seem to remember someone else with a dual setup, and they used two StellarMates. One to control one telescope setup plus the mount, and the second to control the other telescope setup only. You will loose a frame on the second one during the meridian flip, and not 100% sure how dithering works with two. Maybe someone else can chime in who's actually done this. :)

Andrew Burwell replied to the topic 'New Internal Guider Features' in the forum. 1 month ago

I'm pretty sure (95%) I had that unchecked. And stopped using the feature because calibration would trigger after the flip. I use the scheduler, so not sure if it has anything to do with that. I would have to test again to be positive. But I went through several nights of this issue, and gave up on unguided because guiding would turn back on always after the flip. It seems if the scheduler is the master, and guiding is off, it shouldn't "turn on" with a slew.

Andrew Burwell replied to the topic 'New Internal Guider Features' in the forum. 1 month ago

This comment isn’t directly related to the new features, but is related to something you mentioned about recalibration. This has caused me problems in the past when NOT guiding. I use non-guided dither pulses, with no guiding on my 10Micron, but after meridian flip, it triggers a recalibration even though I have guiding off, and tries to guide again without dithering since it does not work with non-guided dither pulses.

So I often guide, even though it can make things worse with a 10Micron that doesn’t need correction. Just some extra info to help make an informed decision on recalibration.

Thanks for your work, I will definitely give multi-star a try. Will multi star eliminate the effects of seeing possibly? Does it average out the movement of all the stars?
