Uh, this is too hard....
I have tried several times but either weather or technique has failed. First my observatory control laptop fried and it took a long time to re install everything.
Now my camera has fried too, just 30 minutes ago. I'll have to send it back to the China but there is a national holiday going on about two first weeks of the October...
I managed to get just a single 20min. exposure before something really bad happened to my cooled astronomical camera. There is a bad tilt in optical axes and other flaws too, I don't count this as a first light.
Single 20 min. exposure of the "Propeller Nebula" in constellation Cygnus.
A new set of wide fields vs closeups
Weather looks kind of good now, I might have something new to publish in few days! I never have had a first light for the Autumn season so late...
Since the weather doesn't support shooting any new material, I have done more image pairs from same target in different focal lengths, usually a 200-300mm camera lens and my old Meade LX200 GPS 12" telescope.
I have done earlier some scale studies from the same material, with Moon circle as a scale.
Now I have done just simple image pairs, showing both, a wide field and a closeup.

A set of wide fields vs closeups
Since the weather doesn't support shooting any new material, I have done more image pairs from same target.
I have shot many targets with least two different focal lengths, usually a 200-300mm camera lens and my old Meade LX200 GPS 12" telescope. I have done earlier some scale studies as a zoom in series, with Moon circle as a scale.
Now I have done just simple image pairs, showing both, a wide field and a closeup from the same objects.
Sh2-142, the "Wizard Nebula"
Ra 22h 47m 0s Dec +58° 06′ 00″, in constellation Cepheus

A collection of images from Australia ( Shot by a remote telescope)
Southern wonders
Images from Northern Galactic Groups remote telescope, narrow and broad band. photos.
I had an access to a great instrument, 16 inch RCOS, in Australia for few months about an year ago, what a wonderful experience! I made this poster form presentation from that material. Southern sky is full of wonders and the site was really dark. I miss this "Stradivarius" of telescopes, my old Meade feels like a toy after this...
A labeled version
A collection of remote images can be found from my portfolio, with technical details:
