Now that's super impressive. A wow.wow,wow x 4.65 crop factor.
Well done.

I saw this yonks ago.... but still thoroughly enjoyed it
What gets me about this, is the f stop....
600 @ f6.3
So 600mm x2 x2 x4.65 ÷ 95mm equates to an f stop of 117!!!
To get an f stop below f5 would need an aperture of over 2200'ish mm
FYI, anything under f5 in the telescope world is classed as fast

Nooo... The crop factor (i.e. 4.65) should NOT be included in the calculation of f stop. It's just the equivalent of taking the centre portion of a FF image after having taken the image, the focal length of the lens and the physical aperture are unchanged. The teleconverters do change the focal length so do affect the f stop. The f stop is actually 6.3 x 2 x 2 = 25.2 .What gets me about this, is the f stop....

I'm still trying to find half an hour when I'm not under pressure to do other things, am still awake and alert and can sit down in peace to watch the video from start to finish!

Cheers Spad, i just notinced i have a DM reply from you. Glad you enjoyed it, yeah the numbers are a little insane arnt they. I hoping for some clear skies and calm conditions as I'm goning to repeat the shoot, but see if I can get better results, both in stills and video. Even if I dont , im still more than happy with the results so far.

Ahhhh.... ok! I've had a learning experience today! Do not include crop factor! Something I didn't know but in hindsight I should have figured out! Considering I don't do it with my telescopes!!! Spad wrote:

Sorry as well to Geoff!! I implied you were trying to ohotigraph thru a tiny smegging pin hole!

What that little sensor in the Q-S1 is really giving you is a lot of pixels in a small area. That means it can resolve a lot of detail (assuming the lens can provide it!) which wouldn't be resolved by a typical FF sensor. A FF sensor with the same pixel density, and thus resolution, as the Q-S1 would have about 270 megapixels. Still some way to go for FF sensor manufacturers...
Come to think of it, is anyone putting a Q-series camera on the end of a telescope and pointing it at stars and galaxies??

If i can get one.... or borrow one... i can give it a shot
Biggest problem will be what is its longest exposure setting or if it has it got a bulb setting?

'Bulb' mode is available if you use a genuine Pentax K-Q adapter, not if a 3rd party adapter is used. The reason is that 'bulb' mode is only available if the lens has a leaf shutter (there is no shutter in the camera itself). The main Q lenses (01, 02, 06 etc) contain a shutter. The genuine Pentax adapter also has a shutter, so the camera believes that any attached K mount lens (and presumably telescope) has a shutter. Non-Pentax K-Q adapters do not have a shutter, so bulb mode is not available with them. Without a shutter in the lens or adapter, the max exposure (via electronic shutter) is 2 sec.Biggest problem will be what is its longest exposure setting or if it has it got a bulb setting?

I did watch this Youtube awhile back too, Geoff's enthusiasm is infectious - great stuff.
