Hello,

Using Hartung’s 2nd Edition I managed to hunt down a few more doubles. The seeing was between 3 and 4/10 with a strong jet stream over Queensland and strong surface winds rattling the ‘scope, but I decided to plug in the Vixen x2 Barlow and just hope to catch a few good frames from each AVI file (1200 frames in each capture).

On these 4 images, the stack sizes ranged from 8 to 36 frames from 1200 frames, an indication of the poor seeing. The colours have been pumped a little, by increasing the saturation in Photoshop. Where the magnitude variation between the companions made the fainter companion(s) almost invisible in the raw image, I used "Curves" in PS to brighten the fainter star(s), altering their brightness relationship.

The post capture processing in Registax and PS CS3 has turned a sow’s ear into (almost) a silk purse.

Cheers

Dennis
