Planetary Nebulae - Summer
 (640 x 480) |
NGC 7048 in Cygnus Magnitude 12.1 - Size 1.0' - central star mag 18.3 13 Sep 2005 - C8 @ f/6.3 - SXV-H9 auto-guided LRGB = 38:16:12:16 min (L = Astronomik CLS) Nice planetary not far from NGC 7000 |
 (900 x 700) Enlarged 150% (900 x 700) |
M57, The Ring Nebula in Lyra Magnitude 9.4 - Size 1.4' x 1.0' - central star mag 15.8 03 Aug / 08 Sep 2005 - C8 @ f/10 (L) / f/6.3 (RGB) - SXV-H9 auto-guided LRGB = 25:8:10:21 min (L = Astronomik CLS) Pretty good seeing but mount was acting up. Did get some good exposures, however |
 (900 x 675) Full size (1203 x 906) |
M27 (Dumbbell Nebula) in Vulpecula Magnitude 7,6 - Size 8,0' x 5,7' - central star mag 13.9 29 Sep 2004 - C8 at f/6.3 - SXV-H9 L:R:G:B = 26:12:11:12 min (L = CLS - RGB binned 2x2) The brightest planetary around, and one of the biggest as well. The luminance was shot one day after Full Moon! The colour exposures are from begin September but then the seeing was too poor for a high resolution luminance shot. Older MX516 images: 18 Jul 2003 |
M57, The Ring Nebula in Lyra
Magnitude 9,4 - Size 1,4' x 1,0' - central star mag 15,8
07 July 2003 - C8 at f/10 - MX516 - L = 14 min (high res mode) - R:G:B = 3:2,5:2 min (C8 at f/6.3 in May 2002)
Famous planetary nebula (and the first ever deep sky object I observed with a telescope). This image was made in a humid summer night with excellent seeing but poor transparency. The colours were created from exposures made during my holiday to Puimichel in 2002. Old image from May 2002 in Puimichel
NGC 6543 (Cat's Eye Nebula) in Draco
Magnitude 8,3 - Size 22" x 16"
07 July 2003 - C8-DX at f/10 - MX516 - 5 min in high res mode - max entropy deconv.
This small but bright planetary is located almost exacly at the ecliptic north pole
NGC 6826 (Blinking Nebula) in Cygnus
Magnitude 8,8 - Size 27" x 24"
28 June 2003 - C8-DX at f/10 - MX516 - 3.5 min (high res mode) - max entropy deconv.
Very bright planetary famous for making tricks with the eye. The nebula "disappears" when looking directly at the central star while it magically reappears when using averted vision.
NGC 6781 in Aquila
Magnitude 11.8 - Size 1.8' - central star mag 15.0
18 Jul 2003 - C8 at f/6.3 - MX516 - L:R:G:B = 15:7:6:6 min
Beautiful planetary in the Eagle but not so bright
NGC 7008 in Cygnus
Magnitude 13.3 - Size 1.4'
28 June 2003 (RGB 15 Jul 2003) - C8-DX at f/10 (RGB f/6.3) - MX516 - LRGB = 13.5:7:6:6 min
