Re: M1 Crab Nebula
Great image Roger! Very nicely processed. One thing I noticed was for a long time the guiding was almost spot-on ... very little corrections, then for a while there would be almost constant corrections (I believe in DEC?). Then it would settle back down. I don't know if this is Periodic Error or som...

Re: Exoplanet Project (#1)
That's great you got the drift guider ready for testing. Hope you get some clear skies. If you think that adding a focal reducer might make things easier I've got a couple lying around unused if you want to borrow one: an AP CCDT67 (~0.67x) and a Meade f/3.3 (~0.33x). If I recall correctly the AP CC...

Re: Exoplanet Project (#1)
Yeah, I agree, traditional guiding would have no problem keeping the guide star centered to withing a single pixel over several hours. But field rotation around the guide star and the differential motion of the two sensors you get with a separate guide scope would be show-stoppers for keeping the ta...

Re: M42-The Great Orion Nebula
Great image Tim!
Thanks for sharing the heat and keeping us warm out there. Though I still think it's cheating

Re: Blue Snowball (NGC 7662)
That's great, Roger. I love how you were able to image the detail within the nebula.
