Captured yesterday with ASI 120 on C9.25 on EQ Mount hand guided and lightly processed in Photoshop Elements

Fantastic detail. How does it compare to visual?

Thanks for your kind words everyone

Visually I could only see a small dot as I was looking through a 10x50 finder. The camera field of view in conjunction with the C9.25 is only approx. 7x5 arc mins and the ISS is travelling approx.1 degree in 1 second when overhead.

Keeping it in the field of view at high magnification for visual observation would be extremely difficult.

Thanks Grimbles

To get the image on the chip the two main things are to start off with a shorter focal length scope - I started with a 6" F5 Newt and to make sure the Finder and camera are perfectly aligned.

I also use a right angle finder with double cross hairs which ensures that when the ISS is centred it isn't hidden behind the cross hairs !

Happy hunting

Don
