True story of greedy over pushing - plain biscuit returned
True story of greedy over pushing - plain biscuit returned
I think Last night I over pushed my 5 inches SCT, using 1 steve mogg extender, 1 eyepiece projection adapter, another eyepiece projection adapter for Toucam Jupiter planetary imaging.
Look at the size of Jupiter in the stacked 640 x 480 frame in 100%
(my god, I think I am way too greedy to take such a big big jupiter with a small scope.)
It was at aboout 9:45 pm, the seeing at that time was worse than earlier time, but still not very bad actually, I think around 5.
Enclosed also the processed pic at 100%, and also 50%. "No more details gain if we increase the magnification too much" is true.

I tried with my setup and the optimal effective focal ratio is at around f/30.elton 寫:Enclosed also the processed pic at 100%, and also 50%. "No more details gain if we increase the magnification too much" is true.

對於不同seeing,光度或曝光時間, 個F值應該會有唔同.Subaru 寫:I tried with my setup and the optimal effective focal ratio is at around f/30.elton 寫:Enclosed also the processed pic at 100%, and also 50%. "No more details gain if we increase the magnification too much" is true.

我係講緊就算夠定夠光, 用f/40以上去oversample, detail都唔會有什麼改進.Wah! 寫:對於不同seeing,光度或曝光時間, 個F值應該會有唔同.
