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
Image is in HST-palette, (HST=Hubble Space Telescope)
from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.

NGC 7000, the "North America Nebula"
In constellation Cygnus
Image is in HST-palette, (HST=Hubble Space Telescope)
from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.

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:
R.I.P Dell laptop at age of ten years...
This was a third time I tried to have my first light for the Autumn season 2011. This time my ten years old Dell laptop, used to run the observatory, died.
I have ordered a new tabletop computer with some extra com ports. There are no 9 pin communication ports in modern computers and many astro gears need one, like active optics unit, TCF-s focuser and Meade telescope control. I bet, the weather will clear up now, since I can't shoot...
Some redone images
I have turned some of my images to a panoramic format for one customer.
They turned to be kind of nice, so I'll publish some of them here.
(They looked wonderful as a large print on canvas)

M8, the "Lagoon Nebula"
in constellation Sagittarius
Image is in HST-palette, (HST=Hubble Space Telescope)
from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.
Original image and technical details:
NGC7000, the "North America Nebula", a closeup
in constellation Cygnus
Image is in HST-palette, (HST=Hubble Space Telescope)
from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.
Original image and technical details:
M104, the "Sombrero Galaxy"
in constellation Virgo
A broad band image in natural RGB-colors
Original image and technical details:
Sharpless 162, NGC 7635, the "Bubble Nebula"
Ra 23h 20m 48s Dec +61° 12′ 06″
Image is in HST-palette, (HST=Hubble Space Telescope) from the emission of ionized elements, R=Sulfur, G=Hydrogen & B=Oxygen.
Natural color composition from the emission of ionized elements, R=80%Hydrogen+20%Sulfur, G=100%Oxygen and B=85%Oxygen+15%Hydrogen to compensate otherwise missing H-beta emission.

Rain and more rain... couple of wide fields vs closeups
