Live Stack Color Display from Individual Filters

Forgive me if this feature is already there, as I admit I haven't tried live stacking yet. I'm wondering if Live Stacking could be made to present a color (or false color) image built up from multiple stacks from different filters on a monochrome camera. E.g. Select the Red filter, live stack until ...

Re: Use the brain and smart histogram for NB filters

Selection - did you press the 'selection' button in the toolbar to activate the selection rectangle?
No, I didn't know about that, I guess because it's not needed during sensor evaluation?

Thanks

Use the brain and smart histogram for NB filters

I'm not sure what changed or if I'm doing something wrong but I previously got a result of gain 61 exposure 725 seconds (1% max dynamic range) then last night I couldn't get any results (under 15min exposure) until I changed the read noise drop down to 10 or 20%? I had 0.06e-/pix sky for Ha, 0.16 fo...

exposure controls backwards for logitech webcam

Don't know if this is important as it is unlikely this cam would be used for astro but it seems the exposure slider works "backwards" for Logitech HD C270. The longest exposure (500ms) produces the darkest image, while the shortest exposure produces the brightest. Oddly, "auto" seems to be OK. So, j...

Re: Polar align cordinates

OK thanks.

Could we live stack to enable a cheap (short exposure) camera to be used for PA?

Re the Celestron Nextimage burst, I see this comment about long exposures:

Re: Polar align cordinates

Do we know if the CELESTRON NEXIMAGE BURST CAMERA - MONOCHROME supports > 1 sec exposure? That's the AR0132 sensor. A little more pricey than I had in mind but if that's the minimum it takes... Also I found a page that is supposedly all long exposure CMOS USB box cams, but I can't find any pricing a...

USB box camera support for PA

Is there support for an inexpensive "usb box camera"? Like the ones used on drones with S mount (12mm) lenses? I'm wondering about an under $75 or $50us solution for Polar alignment, for folks with guide scopes that are too long or using off axis guiding. I would guess IR monochrome would be best? 2...

Re: Polar align cordinates

FYI my FOV is 30.9 x 41.2 arcmin so just at the recommended 0.5 degree.

1.93 Arcsec/pix.

Re: Polar align cordinates

Yeah but I think messing with a dialed in and cinched down autoguide setup to do PA is a bad plan. Going from the 50mm guide scope to the ST80 usually gives people a 2x improvement in guiding so I still think 400mm and 80mm dia is the way to go for a guide scope with large FL reflectors. FYI Orion s...
