Hi Jim;
Pretty good result - much better than I'll ever get.
The seeing forecasts can not predict what local influences do, especially in an urban environment.
When I'm visiting the folks at the cabin in Saskatchewan, the seeing is always much better there than it is in Calgary. Even when the CSK or the NAM Forecast indicate similar seeing, it's always better there.
I attribute that difference to mainly to the heat upwelling from the surrounding city in Calgary, whereas as the Cabin is a few hundred meters from a lake and has flat grass covered fields surrounding it.

Well, seeing was predicted to be near perfect this morning in the Lake Ontario region and from an imaging perspective it does seem to have been better than past days. However nothing to be excited about since there only appears to be an incremental improvement in my images. I'm still not able to resolve the fine festoons in the NEB and EB. My red images seems to suffer loss of contrast as compared to my blue and green and I wonder if I'm losing data in the R channel due to a filter issue. Then again I might also be bumping up against the poor figure of a mass produced mirror. I'm fairly confidant that my collimation is accurate.
