The new baby arrived, gonna test it despite the poor sky condition, I would say seeing 3/10 with transparency 5/10.
I am adjusting myself on the transparency rating, and if I were still in Hong Kong, I would say it's 6//10 and if I were to compare with the previous clear nights, I would say it's more like 3-4/10, even Orion was not too visible to the naked eyes.
With the strong tripod, the mount was steady enough for the Meade 8" SCT. Focusing was tricky anyway, the mirror shift worsen the problem further but that was doable with patience. Patience is cool weather came with a price, especially when you couldn't use the glove.
Anyway, here were the results. First up were prime focus shots on the moon, given the pixel size of 2.9um, the optimal sampling would be like f/14.5 so f/10 is a bit under sampled.
Next up was the Jupiter, I've to adjust my Rigel Quik Finder in order to point at the Jupiter properly, the flip mirror did help but still requires some effort. Adding a 2x barlows means oversampling.
First up is a f/10 shot, but with the flip mirror, I expect it works longer than f/10.
The Jovian satellites were smeared by the wind current. Pushing up with a 2x barlows did not reveal any more detail but worsen actually.
I will try to attach the barlows lens cell to different locations of the optical chain to find an optimal one when weather permits again.
