Hi jimdrever,

very nice image. If i can i would only suggest you to make the background a bit darker (but maybe is only due to my monitor...).

Since I have 2 newton OTAs (1000 mm f/5 and 650 f/5) and a SSAG and i'm interested to buy this camera i would ask you few technical questions about the photo:

- how long were your subframes?

- which kind of guidescope and which guide settings did you use?

I ask you these questions in order to understand how to manage such tiny pixels (2.4 x 2.4 micrometers) with my OTAs (650-1000 mm) without star trailing.

Lastly i would know something about the capture settings and the calibration files (bias, flats, darks) that you have used.

Thanks in advance

Matteo

Thanks Jim, this helps a lot!

Maybe it could be also useful to use binning for long exposures (obviously with a price of a low resolution)

Thanks again!
