Capture

C11 (standard, not Edge) on Milburn wedge
Meade flip mirror
Astronomik 2c UV/IR cut filter
Televue 2x barlow (only the lens unit is used)
Precise Parts adapter
ZWO Atmospheric Dispersion Corrector
ZWO ASI224MC camera
FireCapture v2.6
30 minutes of video is captured for each image, in ten three-minute segments


Processing

Stacked in AutoStakkert!3, using 1.5 pixel vertical and horiztonal blur (Advanced>Experimental Features) to avoid grid pattern artifacts
Resulting images are derotated and combined in WinJupos, with limb darkening set at 65
Pixinsight:
Multiscale Linear Transform for wavelets (with a second less aggressive version to capture the polar cap)
Resample 200%
Curves: balance color for IMX224 sensor
Deconvolution
TGV Denoise
Curves: boost saturation in bright areas
Histo Trans to brighten
Photoshop:
Layer together main image and version with SPC, using masks
Paint out any bright speckles along limbs left over from WinJupos derotation
Remove any edge artifacts (Burn for bright rings, Dodge for dark rings)
Assemble images in template, with albedo maps created in WinJups ephemerides tool


other sizes: small medium large original auto
