I live on a mainroad and each car that passes makes my 4 metre scope shake like a mother. The shake effect seems to be worse on my planetary (this camera) than when I shoot on my large format QSI. I really need better dampening technology in the ground for my pier to prevent those vibrations travelling upward. Anyone know what the straight gully's are caused by in the first photo? Below - Ray's X-wing fighter is clearly shown on the right handside here. I managed to snap its shadow as it was chasing an imperial tie-fighter smuggling the data of a rebel stronghold. The shaky-ness of my pier causes my histogram to spill over and cause the excessive white point. Ray

Incredible work Prof. Ray

Stunning mate. Well done. Ray

Very nice Professor. Ray

Yeah totally agree with Shane. That light pollution map is good. Ray

Wow, one sub! The question begs, why do we need an hours worth if you are getting results like that with one sub? I was in the U.S recently. I was in San Fran, San Diego and then Tuscon. Tuscon has the dark sky laws for Kitt Peak Observatory, the skies were amazing. Regards Ray

Geesuz Prof,. that's some serious stars! Great shots. Ray

Yeah that is a good shot buddy, well done. Ray

Wow mate, 2 laminectomies and a fusion, ouch. Ray

Hi Dave, Check this study out on the National Library of Medicine. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4554252/ Regards Ray

Lovely shot my friend. Ray

Interesting. One thing my AP mount does it appear to remember where it is all the time. Admittedly I paid for the privilege of that though. The biggest draw card (apart from everything else) with the AP mounts is running the cables through the mount. I really find that useful. Ray

Good idea mate. I have to agree, power loss can cause some serious issues. For example, my rotator wants to do a 360 turn every time it is turned on which is really dangerous for plugs and cables that don't have enough slack in them (the rotator is strong enough to snap plugs), so I always keep it unplugged in the event of a power loss. Ray

Beautiful mate. Ray
