If Sequator can not support the RAW of your new camera, you may try to convert your RAW files into DNG format via Adobe DNG converter.
Alternatively you can convert your RAW image into TIFF first via the official software of the camera.

* Sorry for Mac/Linux users, Sequator only supports Windows currently. Linux users may try to run via wine+ vcrun2015.


Please download and install Microsoft Visual C++ 2015 Redistributable Package (x64) before execute. Select vc_redist.x64.exe.
(Otherwise, you may encounter an issue of MSVCP140.DLL not found)
Remember to read the manual before using.

1.4a 64-bit (Oct 29, 2017) - Download  (Latest version)
- Some changes on UI
- New "selective" option on Freeze Ground mode: perform pixel rejection on sky region
- Release 1: LibRaw 0.18.4 (Sep 17, 2017)
- Release 2: LibRaw 0.18.5 (Oct 9, 2017)
- Release 3: Fix bug - reduce light pollution may perform strangely on over-exposed results (Oct 29, 2017)

1.3f 64-bit (Sep 10, 2017) - Download
- Support "Remove all" on image category
- Upgraded LibRaw to 0.18.3-Release

1.3e 64-bit (Aug 31, 2017) - Download
- Updated the algorithm of "Freeze ground" for better quality. Remember to specify sky region before stacking with foreground
- Base image will be selected by file name automatically if only added star images
- Release 2: more natural I.A.A tuning (Jul 24, 2017)
- Release 3: no warning popup for unsupported TIFF tags (Aug 31, 2017)

1.3d 64-bit (Jul 1, 2017) - Download  
- New option "I.A.A." under uneven light pollution filter. I.A.A. is the abbreviation of "Intelligently-Aggressive Analysis." Suitable for the sky glow close to darker foreground.

1.3c 64-bit (Jun 18, 2017)
- New algorithm: improve the quality of uneven light pollution filter
- Fixed some bug of irregular mask
- Release 2: update wxWidgets libraries (Jun 18, 2017)

1.3b 64-bit (Mar 10, 2017)
- Added "Irregular mask". You can use brush to mark the sky region now. Suggest to use with "Freeze ground"
- Upgraded LibRaw to 0.18.2-Release
- 1.3a -> 1.3b will not generate gradient zone for "Accumulation" + "Irregular mask". I think more straightforward.

1.2a 64-bit (Feb 12, 2017) - Download
- Added "align only" option in stacking mode. This function will produce aligned images in linear TIFF format into the output folder.
  Note linear images are darker but suitable for further processing, not bug.

1.1f 64-bit (Jan 21, 2017) - Download
- Release 4: Generate uncompressed TIFF, more compatible (Jan 21, 2017)

- Release 1: LibRaw 0.18.0-Beta1 (Nov 28, 2016)
- Fixed a bug of star detection, which may cause mis-alignment in higher noise

1.1e 64-bit (Nov 5, 2016)
- Slight changes on UI, added open result button
- Adjusted the parameters of star detection
- "Freeze ground" refers to "gradient" for ground for better star quality
- Better corner alignment under complex distortion option

1.1d 64-bit (Oct 23, 2016)
- New complex distortion correction: track the motions of stars between adjacent frames. I call it "DeepTracking"
- Adjusted star detection method in higher noise (experimental)
- Star quality improvement of "Freeze ground"

1.1c 64-bit (Oct 15, 2016) - Download
- New light pollution filter, tends to be more conservative to reserve more details and better color balance
- "Unify exposure" function under the "star images" item

1.1b 64-bit (Oct 7, 2016)
- To handle camera orientation changes while shooting on EQ mount

1.1a 64-bit (Oct 2, 2016)
- New feature: "Select best pixels" which implements sigma-clipping average
- New feature: "Freeze ground" to freeze both stars and ground (see Samples)
"Select best pixels" & "Freeze ground" are under the "Composition mode" menu, suggest to read the manual before using.
- New feature: "Reduce dynamic noises" to detect hot pixels without noise images
- More precise result for large amount of stacking

1.0c 64-bit (Sep 3, 2016) - Download
- Fix the bug of exposure compensation on non-overlapping areas, which may produce dirty pixels
- Add remaining time estimation
- Other bug fixes and optimizations
