RAW mode modified Philips SPC900 NC web camera, unless otherwise indicated, with an IR blocking filter. 8 inch Meade LXD55 SCT and 3X barlow. Registax verions 3 or 4 were used for stacking. Final processing has been done using AstraImage for removing diagonal bands through Fast Fourier Transform edits and for applying deconvolution. Photoshop CS2 or Paint Shop Pro 9 have been used for adjusting levels, curves and color, while Neat Image is used for digital noise removal. K3CCDTools version 1 was used to record the videos unless otherwise indicated. Camera settings recorded with WcCrtl.

Videos recorded with K3CCDTools version 3 using Video for Windows (VFW) in order to turn compression off but I didn't realize that VFW doesn't support RAW mode so the videos couldn't be converted to color AVIs. 1/33 second exposure. Brightness: 50%. Gain: 68%. Gamma 68%. Saturation 50%. 500 frames stacked. Io is in transit with its shadow trailing behind it. Seeing was average to good (about a 3 to 4 out of 5). Angular diameter 44.5".

Unmodified SPC900NC. 1/25 second exposure. Brightness: 50%. Gain: 68%. Gamma 0%. Saturation 50%. 1000 frames stacked. Seeing was good (about 4 out of 5). Angular diameter 45.2". The Great Red Spot is visible at lower left as it emerges from the planet's limb. Images captured with K3CCDTools version 3 and processed in Registax version 4 and Photoshop CS2. Focus Magic was used to improve the image details.
