I’ve been using a tracing panel for exposing flats over the last few months. I made diffusion masks from white t-shirts and embroidery hoops to go over the front of my various telescopes or lenses. It took some exploring and mods to this working reliably, but now I’ve got a system that works for my needs. I use the APT CCD Flats wizard to generate a plan for flats and it’s really streamlined this part of the process. After every imaging session I gather the necessary calibration frames, beginning with the flats. I like your straightforward explanation of the why and how, concerning flats.

i have a flatpanel without a dimmer, and put a few sheets of white paper over it to diffuse it a bit and to get the right ADU.. and then used the flat-frame wizard in SGP to calculate the times (in a few days I'll set this up in NINA) My Oiii flats are a bit over 10 seconds, while my Ha and Sii are around 3.5.. just shows how little light gets through them..

[@CuivTheLazyGeek]

[@fernandoapausa4931]

Thanks Cuiv, great video with some new pieces of new info, as always! May I ask you if you use the Weighted Batch PreProcessing Script in PixInsight to make your frame calibrations or some other? I dont see the possibility to add FlatDarks in that script... If not, should I use the ImageCalibration process entering the Flats as the frames to calibrate and the FlatDarks as Darks for such calibration? Are Bias also needed in the calibration of the Flats? Too may questions, sorry... :)

[@CuivTheLazyGeek]

I use the Weighter Batch PreProcessing script indeed. I'll have a video of it coming soon. Just input your dark flats as Darks in the script - PixInsight will match them to your flats based on their exposure length. Or you could use the dark flats just as bias, since for modern cooled sensors, essentially 1-2s exposures = bias exposure. No separate bias needed for flats calibration with modern sensors. Just dark flats is fine (and the dark flats, as well as the darks, contain the bias in the first place).

[@OlliesSpace]

"Dirty Dirty astrophotographer" omg made me lol🤣. BTW Cuiv if you take images over multiple nights and basically leave the image train unchanged do you always take flats for each night? If I am lazy I tend not to but should I ?? Thanks Cuiv.

Oooh no I am far too lazy for that! As long as I don't touch my imaging train, I'll be reusing my flats over and over, even over weeks or months. Surprisingly, it works very well - turns out those small forces that hold dust motes in place or quite resilient!

Great video Cuiv.

It's probably true. You could likely have the same effectiveness with just bias/dark flat calibration. But I prefer to have darks since they're so easy to take on cloudy nights!

[@RimantasLiubertas]

When you put FFG on the telesope, you moved dew shield down. Would that not change the vignetting and hence flats will not match lights?

[@CuivTheLazyGeek]

Very good question! A properly designed dew shield would not introduce vignetting (or so little vignetting that it is negligible vs scope vignetting). In practice with the small dew shield of the refractor, it doesn't change vignetting. And many people take flats after removing the dew shield (for SCTs for instance - I did that with my EdgeHD) without issues. Technically you are right, but in practice I've never encountered a scenario where that happened.

Hi Cuiv. Thanks for another great Vid. Quick question: is it okay to take both Flat-Darks AND Bias frames. Or should it be one or the other but not both? Thanks again.

Any idea why NINA preview shows flats taken through an l-extreme, completely yellow with two distinct separate peaks in the histogram yet when opening the files with any other fits viewer, they seem correct? Is there some hidden setting in NINA to mess with color balance? Happens only for flats. Using the same Artesky flat field generator. The camera is a 2600MC.

How are you my friend in astrophotography?, well I hope. Many years ago I bought a 7 filter wheel with RGBHa plain filter and a black filter for doing dark frames and also an opal glass filter for flat frames. I had a remote change switch as well as the USB connector, this way to take darks and flats all I had to do was press the appropriate switch with the scope pointed at the zenith, either dawn or dusk sky. It meant that I always had the filter wheel attached for all uses. The improvement today is a flat light panel, as you say, a luxury. Stay safe, greetings from Tasmania 42 South.

Should be fun and remind me of mild UK winters! Take care in your bright skies. I recently got my hand on a Nikkor lens, 300mm f/2.8, along with its telenegative 2x lens system making it 600mm f/4. It is pin sharp, I also got a fairly rare Takumar 300mm f/4 which is also pin sharp. I am hoping to try them out with various ZWO cameras on the SW AZGTi EQ. Mount that I saw you improve on in one of your video’s. I have the ASI air pro (second version still to use) it takes a while to get all the bits and pieces together. Your own experience with ZWO equipment is very interesting, I have many ZWO gems, but due to health issues, some have yet to capture any photons! Note-the front element of the Nikkor lens is 5.25 inches, also very heavy. It will be interesting to see how it performs at different apertures. Also at f/2.8 it is very fast compared to many telescopes.

[@Wheeljack678]

Interesting. With a DSLR in AV-mode, my flats are usually around 1/640. I usually shoot them at the same ISO as my lights, I know this is perhaps not necessary, but I've found that when I do this, my flat frames finally work and I'm afraid to change it up again.

Dark frames yes, as the thermal signal is an important part of the signal that you are calibrating out (thermal + bias). Flat frames no, because calibrates out effects of the optical train - primarily dust motes and vignetting (aka light falloff), etc. These are not dependent on exposure length.

[@christoph4977]

You are so practical Cuiv :D ... but seriously, when taking darks4flats and flats of 2s you REALLY don't need to cool the sensor ... there is no time for any dark current to build up anyway but even if it was, the darks4flats will take care of that. I know you like to err on the side of caution, but in this case this is really unnecessary. Save the cooling energy - save the planet ;)

[@CuivTheLazyGeek]

Something else I will have to test - I do remember testing bias frames a long time ago, and seeing that cooled bias and hot bias were quite different (even though I thought they would be the same), and that's why I'm conservative here...

[@christoph4977]

​@@CuivTheLazyGeek Are you talking about the ASI 1600? This sensor indeed has some strange behaviour on min-exposure lengths. In that case, maybe you are right, taking darks4flats and flats at the given light-temperature might be the safest bet ... however: A bias frame is just the sensor's electircal activity, nothing else. In a fraction of a second, there is no possibility for thermal noise to build up so it is not the temperature introduced by cooling but rather something power related. Which isn't good ... Since it is electrical activity, that is causing bias signal, I would check everything power-related for errors. If your camera is not powered sufficiently, the additional strain of cooling could create all kinds of strange behaviour. Even the cable's proximity to another cable or power source (USB-cable?) with not enough cable-shielding could add unwanted electrical signal. The problem with this is, that this kind of signal would be very unpredictable and would ADD additional noise while calibrating. One thing is sure: there is no dark current in bias frames. It has to have a different source. One more thing to mention. Very subtle differences in the frames will be present. If you subtract one stack from the other and you see only very slight patterns, there is nothing to worry. It is not possible to have two 100% same frames. So maybe subtract a 0° bias from a -15° bias and measure the noise and then subtract two 0° and two 15° frames ... maybe "quite different" is only an illusion? :)

[@CuivTheLazyGeek]

@@christoph4977 I've seen that on two cameras (and haven't tested others): a Peltier cooled 600D (internal battery powered for the camera itself) and the 1600MM (don't remember how it was powered at the time). I was comparing the stacked bias result (and also the superbias), not just the individual bias frames. The fixed pattern just looked different. I can't explain why. It took me by surprise. It doesn't make theoretical sense (especially for the internal battery powered camera). But since then, I just take all my frames for a session at the same temp. I can with a cooled camera, and while yes, in theory it's not useful for flats and flat darks... Well I've seen that sometimes the practice begs to differ. So yeah, I err on the side of caution.
