All these pictures were taken at prime focus with a 10 inch Meade LX200 GPS telescope and a cooled Logitech Quickcam Pro 4000.

This is what I call a 'quick and dirty' webcam experiments webpage.

These are my first images of Jupiter using my cheap wedge. I only did a rough polar alignment before taking these images.

I only let the cooling run at 9 Volt - no Peltier - because of vibration issues

It was clear - after the processing - that the field rotation problem is now solved.

The wedge vibrates too much - I focussed using a much steadier image using the ALT/AZ mount on a concrete pier earlier this week. Because of this, these images of Jupiter are 2 steps backward quality wise.

So tomorrow night's images of Jupiter will be better - since I will put some effort into minimizing the wedge's vibration and slower swaying.

60 seconds exposure - 15 frames stacked	60 seconds exposure - 30 frames stacked
90 seconds exposure - 15 frames stacked	90 seconds exposure - 30 frames stacked	90 seconds exposure - 45 frames stacked
180 seconds exposure - 15 frames stacked	180 seconds exposure - 30 frames stacked	180 seconds exposure - 45 frames stacked

• 60 seconds still best exposure time

• 15 frames still has most detail

• Field rotation solved - 180 seconds not as smeared as before

These settings are valid only for my circumstances: 10 inch SCT, prime focus Jupiter webcam astrophotography using a Logitech Quickcam Pro 4000.
