Allow specific values for RGB Multipliers not just Sliders (on 0 Color Settings) and saving Presets

Skye Goodrich — Sat, 28 Mar 2026 23:14:53 +0000

Allow specific values to be entered for RGB Multipliers not just Sliders (on 0 Color Settings), and saving Presets, so I can save a Preset (R/G/B) white balance per Color Camera (not just DSLR). Many graphics software permit saving of white balance presets for the purpose.

APP won't remember the Integrate Percentage Slider

Skye Goodrich — Sat, 21 Mar 2026 13:46:04 +0000

Although most settings are stored between sessions, APP won't remember the integration percentage "lights to stack" such as if I set it on 90% one session, it forgets and goes back 100%. Suggest have it remember what I set last time.

what reasons can it have when integrating sony a7rv subs with astropixelprocessor that the stack show a lot of artefacts when a single sub does not, especially when the light pollution gradient is removed?

Hello,

been using APP with Nikon and ASI Zwo mono for a while, trying out a Sony a7rV

one subs looks like this after lightpollution:

10750

but doing a normal stack as usual, I kepp getting strange pattern when applying LP substraction:

10752

any idea why? One subs is 30s, the stack 1 hour total

does APP apply LP too strong? Even if so these paatern should not appear. IN the single subs there is nothing

10753

Help - integrated images all blank - Why?

Charles Thody — Thu, 19 Mar 2026 10:30:58 +0000

Hi. have been using APP for a long time and never had any trouble until today. Loaded 54 FITS of M64 and used the normal settings I've used all along. Master calibrations files all assign themselves etc but when it come to integration there is suddenly nothing. So have tried a trial with other data files I have that have worked before - nothing. APP reports Integration 1 has ISO/gain of 0.000 and the screen is just black.
Any ideas will be greatly appreciated as this has me totally baffled. Thanks.

ToupTek 585 Color, one session o.k., the next is green ?

Hi,

I have made two automatic session in one night. The first with NGC3628 worked fine in APP, the next session with M13 (same Darks, Bias etc ...) the picture is only green, also if I click "neutralize bg". The single subs were shown right.

Here a single sub (pattern in Fits-Header is RGGB)

10749

and this is the stacked result:

10748

Interesting is that if I open both fits in f.e. ASI Fits Viewer, both look like the single sub.

Whats wrong here please.

Vela Supernova Remnant

John Connor — Sun, 15 Mar 2026 08:43:24 +0000

This is a four panel mosaic of the Vela Supernova Remnant, in HOO (with RGB stars). Not really going for subtle here.

Shot from suburban Canberra, Australia. I'm guessing this target is too far south for most in the Northern hemisphere.

Please don't look too closely at the stars - I'm having some backfocus and tilt issues.

downsized for posting.

All of my color shots using ZWO ASI585MC Pro have a Green cast

Skye Goodrich — Sat, 14 Mar 2026 16:19:29 +0000

Using all default settings, All of my color shots using ZWO ASI585MC Pro have a Green cast. I don't think this is because of Bayer RGGB matrix or extra QE sensitivity to Green, as the APP software should be demosaicing for this (i.e., it will fill in missing red/blue/green).

Comparatively, my ASI585MM Pro shots with filters look wonderful, color is very balanced.

running out of disk space

Terry Snapp — Fri, 13 Mar 2026 19:15:27 +0000

How do I address this problem when I get messages that I am running out of space ? Can I add more space? If so, how?

I have 2 TB of space in my cloud drive...can I access that? what can ido to solve this problem?

Can you Help me?

I am trying to process images in APP and can't get it to work with my SCT. I have used APP in the past with my refractor images and everything seems to go smoothly. For the last few nights, I have been taking photos with a 9.25 Celestron SCT and I keep getting very fuzzy stacked output. The individual frames look OK, but when I stack them I get a very fuzzy looking image. I'm sure I am doing something wrong, but I can't figure out what it is. I've tried shortening exposure times and playing around with APP settings, but I still have the same problem. The guiding seems decent. I've run out of ideas. Can you help me? I've attached an individual sub and a typical stacked result. Thank you!
