RE: Subframestudio - Auto-Rotate After Meridian Flip

RBA — Mon, 12 Oct 2026 06:53:36 +0000

Would it be possible to add an option to automatically display all preview images in the same orientation, regardless of whether they were taken before or after a meridian flip?

Hi Emiel,

I finally got some time to work on this. It should be in on the next update (v1.0.10), coming out soon.

Thanks

RE: AdaptiveWorkflow 1.0.0 – two issues in Preprocessing-OSC (no bias, flat-dark exposure).

Congratulations on AdaptiveWorkflow – I ran Preprocessing-OSC on its release day with a real data set and got a clean stack in about half an hour. While doing it I found two problems and have one suggestion.

Hi Sergiusz,

Thanks for the detailed report. All reported issues have been fixed. They'll go on AdaptiveWorkflow 1.0.3.

RE: AstroThumbs

I have installed AstroThumbs for Windows on two almost identical Windows 11 systems. My Notebook displays the thumbs and file views, but my desktop does not. Desktop knows keyword items in columns, but no thumbs and file views. I have refreshed my thumbnails several times without success. Everything seems to be installed correctly, but it does not work as expected. What can I do? Where can I check the registry for the proper entries?

Do JPEGs show thumbnails on the desktop? If not, it’s Windows, not AstroThumbs:

Folder Options > View > “Always show icons, never thumbnails” must be deselected.
Folder Options > View > “Show preview handlers in preview pane” must be selected.

If yes, let me know and we'll keep digging.

RE: How to use with separate star and starless images?

RBA — Mon, 12 Oct 2026 05:31:54 +0000

I am just getting started with this and according to the help there is supposed to be a way to use it with star only and starless images generated by other software but the help does not make sense as the options mentioned do not seem to exist. Any help would be appreciated as to how to use such images in the software!

Sorry for the late reply. To load a starless image and a stars-only image,use the last button in the toolbar of the main window.

Hi Rogelio,

Congratulations on AdaptiveWorkflow – I ran Preprocessing-OSC on its release day with a real data set and got a clean stack in about half an hour. While doing it I found two problems and have one suggestion.

Setup: AdaptiveWorkflow 1.0.0 (trial), PixInsight 1.9.5 build 1706, Windows. Data: Player One Ares-C Pro (OSC), N.I.N.A. 3.2, 119 lights x 180 s, 40 darks 180 s, 50 flats, 50 flat-darks (IMAGETYP = 'DARK', ~11.2 s), no bias frames.

1) No bias -> run fails at "Master bias"
With no bias frames the "Master bias" integration step is correctly skipped, but the next Images step reads from {workdir}/masters, which does not exist yet, so the run stops with: "Master bias: The folder H:/.../masters does not exist." Creating the empty folder by hand fixes it. Perhaps the step could treat a missing folder as an empty list, or the folder could be created at the start of the run.

2) Flat-darks never matched (exposure rounding)
"Exposure of the flats" reads EXPTIME = 11.21243 from the header, but the Flat-darks rule EXPTIME|EXPOSURE == {fexpo} is evaluated as == 11.2124 (the log shows it that way). The flat-darks have 11.21243, so 0 of 259 files pass and the flats go uncalibrated ("Flats without bias"). It looks like {variables} inside rules are formatted with 6 significant digits, as in messages. Substituting the full value, or comparing exposures with a small tolerance, would fix it. My workaround was EXPTIME|EXPOSURE < 60.

3) Suggestion: rejection algorithm by frame count
The Integrate step proposes WinsorizedSigmaClip by default, while its own prompt says ESD is better from 25 frames up. With 119 frames I switched to ESD by hand. A Branch on the number of frames could choose the default.

Minor: Check reports "writes/replaces existing files outside the work folder" for steps whose output is {workdir}/..., which looks like a false positive since {workdir} is not expanded at check time.

I can send the .awf file and the full log if useful.

Also, I couldn’t copy text from the log panel to the clipboard (Ctrl+C / paste into Notepad did nothing).

Best regards,
Sergiusz Gobiecki

Subframestudio - Auto-Rotate After Meridian Flip

EPK — Sat, 03 Oct 2026 15:10:42 +0000

Hi Rogelio,
I would like to suggest a small feature for SubframeStudio that could make visual inspection and blinking of subframes more convenient.

Would it be possible to add an option to automatically display all preview images in the same orientation, regardless of whether they were taken before or after a meridian flip?
This would make blinking through an entire imaging session much easier, since the target and star field would remain in a consistent orientation throughout the sequence.

Kind regards,
Emiel Kempen

The screenshot on the PI ThemeStudio page clearly shows the full categorized list of themes, including themes such as Autumn Maple, Coral Reef, Deep Sea, Desert Storm, Honeycomb, Koi Pond, Monsoon, Nordic Cabin, Peacock Plume, Volcanic, etc.

None of these are present in my installation. “Reinstall Built-in Themes” installs exactly 23 themes, and the themes folder also contains exactly 23 folders.

So my question is simply: how do I install/download the remaining themes shown in your screenshot to get the advertised 80 themes?
