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

Dissapointing first results with the #126 Shorty Meade 2x Barlow lens on the right.
Better first results with the #124 Meade 2x Barlow lens on the left.

Picture of Mars (on the left) taken from AVI made on 22 June 2003 at 0:13 (early in the morning)
Exposure time of each frame: 1/5 second. 5 frames per second were taken for 60 seconds.

Lessons learned

I was not happy with the image quality of the #126 2x Shorty Meade Barlow. I exchanged it for the #124 2x Meade Barlow.

I am much happier with the image quality of the #124 2x Meade barlow.

The way I understand this result is that the shorty barlow is for telescopes with shorter backfocus travel than a SCT telescope. So it is a 'compromised' design for a SCT with enough backfocus travel. The normal length barlow provides much better results.

Disclaimer: I never had both these barlows available at the same time to do proper comparisons. But from what I can remember about the shorty barlow, I am still convinced that the normal length barlow is a MUCH better choice for doing f/20 webcam astrophotography through a 10 inch Meade SCT.
