Re: askar c1 and c2 filters

I assume You used a color cam and split the channels. From one stack You'll get: R= Ha and G/B = O3. From second stack You'll get: R= S2 and G/B = O3 A better way might be to do a third stack with images from both filters to increase integration time for O3= G &B channels to reduce noise Then load S...

Re: Processes or tools for removing moon glare?

Please don't talk weather, it's the same here in Germany.... :-( I try to get around the noise issue by doing Luminance shots using a Duoband filter which creates the highest signal / shot noise ratio (at least for faint Ha & O3 objects). It's not helpful for Stars / Galaxies, but as they are bright...

Re: Repair Module

Hi Melty, I definetely agree on the Redistribute part here. Mostly I don't need Repair at all, thanks to my APO but if I do, I usually use Warp. Sometimes Redistribute creates "Saturn-like" globs with surrounding rings. I think that this is highly dependent on the star mask, and this is where improv...

Re: Astro to Astro-art Continuum, 2024 Edition

these are _local_ contrast enhancements and for me _local_ contrast enhancements are always a ‘ manipulation of reality’ Hi, I'd say in this regards, all Post Processing would be a manipulation of reality. Think of an Arcsinh stretch, White balancing or whatever. The key point is the conditions det...

Re: Sky Glow parameter in FilmDev

Hi,
Jeff's idea for black point touch up might be a potential feature for a (future) touch up module: introducing subtle dithering, e.g. using Denoise's "Grain Equalization" parameter, while adjusting black point. Thus it would apply signal theory properly, avoiding clipping.
Clear Skies,
Jochen

Re: OptiDev final stretch ‘Ignore Fine Detail’ (pre-) setting

Hi Dietmar, This might be a non-issue, leaving the IFD after BIN the same value as before BIN is the real issue here Whether or not You set IFD in the initial stretch, WIPE will always carry over the IFD of the final stretch! Consequently, If you choose to BIN, You'd have to readjust IFD anyway, so ...

Re: Mosaics+calibration frames+stitching+StarTools: How?

Hi kodo, the thing with the flats is: 1) If You just intend to calibrate for vignetting, You would just need one set of flats per orientation of Your optical train. In such case, a 3x3 blur of the flat may help reducing noise. 2) Flats are also used to compensate for dust specks, stains etc., though...
