The weather since February in Sydney has been terrible!!! Only in the last week have skies cleared enough to resume collimation.

This is a single 5 minute exposure in the vicinity of NGC 6681 that was taken after some tweaking of collimation. The seeing was excellent (for Sydney) and the best I've had so far. The drawback of course is that good seeing shows up even minor collimation issues!

The good news is the smallest discernible separations are arounbd 1.5 arcsec. Only calibration (with sub-optimal flats) and stretching was done. There was no deconvolution or sharpening done of any kind. Though collimation is not yet acceptable to me, particularly on the right hand side, I'm getting very close now and this is an very heartening result!
