Info Post






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.








"Rosette Nebula"


Ra 06h 33m 45s Dec +04° 59′ 54″, in constellation Orion








Image is in HST-palette, (HST=Hubble Space Telescope)


from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.

















Sharpless 162, NGC 7635, the "Bubble Nebula"



Ra 23h 20m 48s Dec +61° 12′ 06″










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.
