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)

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.
