NGC2070 2 Fields of View

 Taken 31st October 2017 with Canon 30D (Modified) Skywatcher 6 Inch (150mm) Matsukov.  5 X 2 minute frames stacked with flats and bias frames and processed and enhanced in Nebulosity and Photoshop.

For comparison below taken in July 2017 a wider field of view taken witha Canon 450D and Skywatcher ED80.  The 1800mm focal length of the 150mm Matsukov provides greater power with a wider aperture and subsequent magnification when compared to the 80mm Refractor with a 600mm focal length.  Basically 3x the magnification and almost double the light collecting ability.

NGC253 Sculptor Galaxy 23rd August 2017

Spiral Galaxy in constellation of Sculptor, 12 Million Light Years distant.

Camera:                                                Canon450D Modified
Telescope:                                             Skywatcher ED80 on EQ6 Mount
Guided:                                                 Meade DSI C and Prostar 50mm Guidescope
Raw Frames:                                         5 X 2 minutes
Stacking,Stretching,Noise Redn etc:    Nebulosity
Further Processing:                               Photoshop CC

Not taking flat or dark frames these days.  Dithering during image acquisition reduces the image noise and the spot healing brush tool in Photoshop removes dust mote blotches and hot pixels from the image.

Blanco1 Open Star Cluster

This cluster pretty much fills the frame.  These stars sit about 850 light years distant.  The cluster was discovered in 1949 when a Puerto Rican Astronomer noticed these stars were all of a similar type.
Imaged with Canon 450D and Skywatcher 80ED. 3 x 2 Minute exposures.Processed in Nebulosity and Photoshop.
