I am getting back to some planetary imaging after a hiatus, and want to understand the most optimal workflow and equipment.
Luminos 2.5 barlow (hope to get a 2x PowerMate soon)
ZWEO Atmospheric Dispersion Corrector
ASI290MC -- for RGB OSC using a UV/IR cut filter
FireCapture via USB3
Gear to add:
ASI462MC -- for IR with an IR-pass filter
- Find target
- Focus using ASI290MC for RGB
- Capture ~3 1.5 minute runs at roughly 75 fps (~13ms) with whatever gain gets me to an 80% histogram
- Quickly switch to ASI462 for IR (or I could always use the ASI462, but switch filters -- they're fairly similar)
- Quickly focus the ASI462
- Capture ~3 1.5 minute runs at 75 fps like above
My problem is that to either switch filters or switch cameras requires time -- then more time to focus. With the multiple video runs per filter, Jupiter will rotate a fair amount and the IR images will see rotation compared to the RGB images. So how do people do this with multiple filters?
I Googled around a bit, but couldn't find a UV-CUT/IR-PASS filter (or, I guess just a UV-Cut filter would be the same thing). Such a thing would be awesome -- I don't want that skewed, bloated UV light but do want IR for the banding in the gas giants. Is there some reason why capturing both RGB and IR in the same images would be bad? I understand you can't really process them differently in that scenario, but wouldn't this be better than the 3-5 minutes it might take to switch cameras and refocus?
