Mars at opposition the night of October 13th from Austin, Texas. This may be my last chance to catch Mars at a good size this opposition, 22.3 arc sec. Seeing was a bit better than the night I made my time-lapse and I experimented with IR cut and pass filters. This image is just with the UV/IR cut filter and a Questar telescope 1350/89 mm with a Dakin 2x Barlow lens was used with a ZWO ASI224MC planetary video camera.

Camera gain 136 (unity gain 135) and exposure 30ms. Best 25% of 7997 frames 3x drizzle stacked in AutoStakkert!3. Wavelet sharpening in Lynkeos. With final exposure, crop, and downscaled 2/3 in Photoshop for a 0.145 arc sec per pixel scale.

Here is an IR shot, best 50% 1.5x drizzle stacking. The ASI224MC has similar response to near IR through the RGB filters in its filter array, so it is possible to capture infrared images.
