UPDATE FROM MABULA
I have had a very rough 2 months unfortunately health wise. I was struck 3x in a row with bacterial infections. The second infection occurred after a routine hospital checkup and I became very sick. I had to rest and take a lot of antibiotics. Once I was recovering and restarting work 1 month ago, I again became sick. The infection was not yet gone, so even more antibiotics and rest was needed. Needless to say, it took a lot of my energy and I needed a lot of rest.
Finally, the infection is really gone and my energy is coming back step-by-step now and I have started work again. I am terribly sorry to have kept you waiting for support. I will address all outstanding questions and e-mails step-by step and will be on the forum daily from today.
APP 2.0.0-beta47 will come soon as well, a lot of work was already completed before I became very ill, so the release is also nearly ready for you. Beta47 will be much faster actually. Many workflows will be more than 2x faster, mosaics can even be 10x faster than before because registration really received a major boost... all compared to beta46. Before I release it, I will make sure that everything is working properly and then I will release it.
Hi, it has been quite awhile since I've imaged with my DSLR, which is a Pentax K-5iis. But since I recently acquired an Astro-Tech AT8RC of 1625mm focal length, I wanted something with a bigger sensor and bigger pixels than my 183MM Pro.
I've noticed that when I capture FITS files with Ekos, and pull them into APP, they have a VERY pronounced green cast. The first image attached here is a screenshot of such an image -- just some rando shot out the window on a grey day, should be pretty close to a neutral color balance. Notice that the FITS header specifies a "BGGR" pattern, which I've also selected on Tab 0. (I get identical results to this if I leave the pattern at "Supported").
The second shot shot shows what appears to be the correct Bayer.
First, thanks for including the option for the right one, but secondly, wow, what is actually going on here?
I think this camera has a regular sensor right? RGB would then ben the right one, it can cause a green cast due to the sensor having more green pixels overall. This will be calibrated later during processing.
@vincent-mod Yes, it's just a standard Sony DLSR sensor, I can't remember where I looked up the Bayer pattern but the BGGR in the FITS header sounds right to me. The tooltip in APP for the RBGGGGBRGGGG... filter pattern is "select this if 'supported' doesn't work" or something like that. It does seem to work, but I was just curious.
Yes, it also mentions "for X-trans sensors", which are quite different. 🙂 The green cast is not abnormal and will be calibrated out later.
So just to be crystal-clear here: Are you saying I should use the BGGR setting when I import the FITS files, instead of the (much longer) that yields correct-looking images when I double-click them before calibration? I'm probably not going to bother with darks, back when I was using the K-5 all the time I determined that the IQ was at least as good (and maybe better) without them. Flats and bias, though, of course.
That's indeed what I'm saying yes. BGGR already shows there are twice as many green pixels in the pattern, this is what you see then in the first raw images.
When you switch on "neutralize background" on the right of the application, it should correct for that. Switch it off when processing again.
