Yes. "Too easy" I would say.
<em class="quotelev1">> Can you tell us what camera really took the picture.
It was a Philips Vesta 675K with the simplest SC1 mod (no amp-off).
The scope was a C8 + my own home-grown flip-mirror adapter. As is stated on
my website "The image is composed from 70 exposures, each 30 seconds. The
image was captured in C8 prime focus (f/10). Summing and dark frame
subtraction was done in Registax. Richardson-Lucy deconvolution in IRIS.
Final colour adjustments in Photoshop."
<em class="quotelev1">> Thanks for posting the link showing Astromeccanica's es640 with a
<em class="quotelev1">> Astronomica label! It seems to prove there is some connection. The

Of course.
