On those white light convection cell images, how many seconds/frames of video do you capture for each image on average?
I did a single run on them. I did 1,000 frames, took about 10 seconds. The seeing was good enough that I just focused, could plainly see the cells, did a few seconds of capturing at high frame rate and was done. I stacked 61 frames.
I see you are using the ASI 290. I've heard mixed reviews about using it for Solar imaging. I was actually turned away by a vendor who said that the frame rate is not like what is advertised by ZWO. The images look great so I'm not sure what to expect or why it was not recommended. What kind of frame rate are you experiencing? Thanks.
I switched out my IMX178 sensor to the 290MM sensor, despite the shutter difference. The 290MM doesn't have grid problems and the frame rate is high. 100+ FPS is not uncommon, depends on a few factors, but I'm recording over USB3 to a SSD and the frame rates are plenty fast and comparable completely to my IMX174 sensor, but with 2.9um pixels which allows me to use shorter focal-ratios and less glass in the pathway. The 290MM is quite sensitive in the Red/IR range. I was surprised that the exposure values on such small pixels were doing so well. I've used it for 430nm, 393nm and 656nm and 742nm and it handles all these wavelengths fine, no weird grid stuff, everything's good. It has a different sensor shape, being more of a rectangle, but beyond that, I'm happy with it so far as a solar imaging camera (and I use it for high res lunar too and it's excellent there as well, very sensitive and can handle 742nm great). Thing is, there just isn't another option with small 2.Xum pixels that can do 100+ FPS yet, so the 290MM is it.
