Hi Mike!

Thanks, real helpful!

I recognize the challenges of using an EL panel for flats. It needs to be very much dimmed to allow these longer exposures. So how to you solve that? My current solution is to dim it with a white t-shirt folded twice. But the t-shirt risks introducing new color shifts (it is white, but....)..... so good ideas are very welcome!

Hi!

I'm too new with the ASI294 to really tell, but I think these settings are confusing. At least it would be better for a user like me if Indi defaulted to 0.5. I am using that setting now, and get great results in PixInsigts! No strange colors after calibration, very nice process!

As for a use case where these settings could be useful: I'm not the one to tell, but I'd prefer going for having them available as long as the defaults are good.

Hi!

The PI guide to calibration was indeed very informative and thorough! Clarifying not least some things about dark optimization that I hadn't realized.

Just to show you: here's a single shot, uncalibrated, of M27, the histogram from Histogram Transformation and the STF. This is taken with the default settings (WB_R = 0.52, WB_B = 0.95). The image is stretched with STF, with unchecked "linked channels", and thus shows a fairly well balanced image, I think - though still weak in red... The histogram shows the colors regarless of the screen strech - and there the difference is quite obvious. However, Maria, I am not sure what you mean by unlinking channels in HistogramTransoformation (but that is perhaps a bit off topic for this forum). I use ColorCalibration to adjust the levels of the RGB channels, but maybe there is a better way.



Anyway, that is post acquisition processing. What matters most here is the acquisition. So what I take from this is that 0.5 for both WB_R and WB_B is a good way to go. But, just out of curiousity, why is the default value something else??

Hi!

Thanks for you replies. Maria, very informative, I need to dig a little deeper into what you are writing!

Steve, as for the debayer direction - I saw about that in the other thread. But I am not sure I even understand what it means. TO the best of my knowledge, there is no option for direction of the debayer in Ekos and neither in PI. But we force debayer pattern to be RGGB. So: are you suggesting another debayer pattern?

Hi!

I've just bought an ASI 294 color camera, and that is real fun! But I get strange colors - a strong blue tint like others here have talked about, and I have a feeling of a weak red channel. Now, I process my images in PixInsight and the strange colors stay with me after calibration and stacking.

So: the rest of you with this camera: which settings do you use for the channels in the Indi manager?

Hi!

OK, so.... stupid question: how do I create an alias....?

And what about having 2 capture modules? Is there a way to do that?

Hi!

I recently arranged for a side-by-side setup. And I have 2 DIY focus controllers, using the Moonlite driver. So I set it up with one foucser as Moonlite, and one Aux as Moonlite. But it seems to cause problems, interference. ANd I realized that I cannot capture with 2 cameras... there is only 1 capture module (I can switch but not operate simultaneously).

So: how can I make this work so I can use both focusers and cameras simultaeously? I use a StellarMate - should I have 2....?

Magnus Larsson replied to the topic 'Where to set focus offset for different filters?' in the forum. 1 month ago

Hi!

I'm not sure what you mean with setting it in the sequence queue. You can access this offset window from several places, if I am not mistaken, for instance from the Capture module. And they are global settings. When changing filter, these offsets are used, regardless of what is in the Scheduler sequence. So: global. You set them once.

Please correct me if I misinterpreted.
