Trapezium in M42, seeing 3-4, C11 primefocus - webcam 256 video frames processed in Astrostack, unsharp mask, levels mag11 stars E and F visible in combined frames due to freezing of the seeing by short exposure (1/20 sec) each frame |

T-Lyrae, a so called Carbon star at position RE 18 32 20, DEC +36 59 55 very impressive by its intense copper-red Color seeing 4-5, C11 primefocus - webcam 450 video frames processed in Astrostack, unsharp mask 4, levels |

V-Aquilae, a second very red star at position RE 19 04 24, DEC -05 41 06 seeing 2-3, C11 primefocus - webcam 350 video frames processed in Astrostack, unsharp mask 4, levels |

M 42, the Orion nebula imaged by digicam during good seeing at 10°C,
C11 with 40mm Pentax + Nikon CP995 in wide mode, single unguided exposure of 60 sec with NR, image size reduced; levels, color balance and gaussian blur in Photoshop The extent of the nebula is quite far for 1 minute exposure, see comparison to 8 sec exposure at: Nikon CP-995 review |

M 57, the Ring Nebula, my first deep sky shot with the new MX7C camera!
C11 with reducer at F/5.5, single shot 60 sec unguided in progressive mode, log levels and DDP in Astroart, colors had to be corrected in Photoshop. |
|
The second try with the MX7C, this time on NGC 891, a dusty edge on galaxy in Andromeda at RA 2:22.6, Dec +42:21.
Its hanging there ghostly and faint (seems less than mag 10!), barely visible in the C11 under mag 5 light polluted sky! Problems with the guiding -star2000 not yet working- forced me to combine 5x 60 sec images Good transparency and steady seeing, no wind at -3°C C11 with f/5 reducer in progressive mode, Drive errors removed by maxentropy deconvolution in Astroart; levels, gaussian blur for faint structures, unsharp mask for stars in Photoshop. color synthesis did not yield useable colors. |

Mars and Uranus are now having a relative close approach with less than 1° Good transparency at -4°C, 4" refractor with 40mm Pentax afocal + Nikon CP995 in wide mode, 4 exposures each 60 sec unguided with NR combined as mosaic, image size reduced; levels, mild unsharp mask.

M 42, the Orion nebula and NGC 1977 (running man nebula) imaged by CP995 digicam in a cold winter night at bad seeing and -7°C;
Top: 4" refractor with 40mm Pentax + Nikon CP995 in wide mode; 4 exposures of 60 sec combined, noise reduction by "blackframe"; levels, gaussian blur for colors in Photoshop, size reduced to 60%; Bottom: C11 with 40mm Pentax + Nikon CP995 in wide mode, 3 exposures of 60 sec combined, same processing; The camera again benefits from the low ambient temperature; raw image: here |

A galaxy trio: M81, M82 (distance 12 mio light years) and NGC3077, imaged by CP995 digicam at bad seeing and -4°C with nearly full moon! The sky background saturated the image to 40% in 1 minute; Top: 4" refractor with 40mm Pentax + Nikon CP995 in wide mode; 12 exposures of 60 sec combined, noise reduction by "blackframe"; levels, gaussian blur for colors and background in Photoshop, M81 and M82 were superimposed from the seperate C11 shots; size reduced to 50%; Bottom: M82 with C11 + 40mm Pentax + Nikon CP995 in wide mode, 9 exposures of 60 sec combined, reprocessed April 2002; comparison to raw image: here |
