Description

Here the firstlight from my new remote hosting spot.

10hrs LRGB split 50:50 between Luminance and RGB. Unfortunately another 4hrs had to be rejected due to high clouds.

In the widefield many interesing background galaxies like PGC2456975 and other objects like quasars can be discovered.
Terribly sorry for the folks living in NGC5474 having cut their galaxy in half ;-)

To my estimation objects down to 21mag or even a little more can clearly be seen.

A little downside, 86 Uma a pulsating variable star with V 5,69 mag left his footprint in the widefield bottom left.

In this regards I must admit processing-wise I am not the most patient, surely some well-skilled colleagues would have gotten out even more from the image especially in the widefield.
However, I am happy and have found a good new spot for my equipment.

In fact not only the first image from the new location but also the camera is brand new and the combination TOA+flattner is also new as have used it wiith the reducer only so far.

Kind regards,
Alex
