What’s New
What’s New
This release imports the latest System Compare and Exposure Explorer catalog work into the spectral-response teaching view, with weak-proxy items called out where the source data is less complete.
New cameras
- QHY247C, marked as weak QE-proxy support
- QHY183C
- QHY MiniCam8M and MiniCam8C
- ZWO ASI678MM and ASI678MC
- ZWO ASI294MM Pro Bin 1 and Bin 2 readout-mode entries
New filter support
- Baader IR-Cut Moon & Skyglow Neodymium
- SVBONY SV260 Multi-Bandpass, marked as estimated / provisional spectral support
- SVBONY SV220 Ha/OIII 7nm
- SVBONY SV220 SII/OIII 7nm
- SVBONY SV220 Ha/OIII + SII/OIII combo workflow
Model notes
- Spectral Explorer now mirrors the new camera and filter choices added to System Compare and Exposure Explorer.
- ASI294MM Pro Bin 1 is treated as a distinct readout mode rather than ordinary software binning.
- Weak or estimated curves remain labeled in the UI so they are not mistaken for lab-grade spectral measurements.
