The supernova remnant in Cygnus variously called the Veil Nebula, the Network Nebula, the Lacework Nebula, or the Cygnus Loop. Nearby is the bright and large star cluster NGC 6940 over the border in Vulpecula. It is obvious in binoculars but not often recorded in the same frame as the Veil. But the wide field of the little RedCat astrograph is ideal for framing such Milky Way starfields. This shows both the eastern and western halves of the Veil as well as the little bits in between such as prominent Pickering’s Triangle component. This is a stack of 7 exposures, each 8-minutes at f/4.9 with the William Optics RedCat 51mm scope, and the Canon EOS Ra camera at ISO 3200 and with the Optolong L-Enhance dual narrow-band filter in place for all exposures. It picks up the Hydrogen-Alpha reds and Oxygen III greens very well, but with little of the cyan tint usually associated with OIII visible in this case. The field is 8° by 5°. Encroaching dawn twilight prevented me taking a set of unfiltered images to blend in with these but they would not have been as essential for this field. Shot May 27/28, 2020 from home.
This is the roughly 10°-wide area area in Vela containing the fragmentary Vela Supernova Remnant (semicircular magenta-cyan arcs of nebulosity at lower area of field,) the Pencil Nebula (aka Herschel's Ray, or NGC 2736) at left of centre, and the large HII regions: Gum 17, 15 and 14 (left to right, with Gum 17 the most obvious just right of centre and above). Two brightest patches at lover left at Gum 25 (left) and RCW38 (right). The bright star at upper left is Suhail, Lambda Velorum. This is a stack of 9 x 2 minute exposures at f/2.8 with 135mm Canon L-series lens and filter-modified Canon 5D MkII at ISO 1250. Some light haze came over at the end of the sequence. Taken from Atacama Lodge, Chile, May 2011.
The Vela Supernova Remnant thin magenta-cyan arcs at centre) plus large reddish emission nebulas mostly in the Colin Gum catalog of nebulas with no NGC numbers. all in Vela. This is a stack of 5 x 6 minute exposures with the 135mm lens at f/2.8 and filter-modified Canon 5D MkII at ISO 800. Taken from Timor Cottage, Coonabarabran, Australia, Dec 16/17, 2012. Blue star at lower right is Regor, or Gamma Velorum, aka Suhail al Muhlif. North is up in this photo. It is not oriented along the Milky Way. Biggest brightest nebula is Gum 17, smaller one upper right of it is Gum 14, and larger faint nebula upper right of it is Gum 14. Small intense spiral shaped nebula left of centre and right of yellow star All Suhail is Gum 20. Small 3-part nebula at lower left next to star is RCW 38. Pencil Nebula, NGC 2736 is at lower left above RCW 38.
