up one night later into the evening/morning. In the photo above, you can see our impromptu "recharge station" powered by a 2000 watt generator. The Hyundai generator ran like a champ all week. It consumed about 6-7 gallons of gas in total and ran about 35 hours.
Here's our two setups (partially disassembled) during the daytime.
On our 3rd night out, I got a chance to photograph the Helix Nebula (NGC 7293) located in Aquarius which is in the eastern-southeastern part of the sky. This part of the sky doesn't contain many obvious targets for a smaller telescope, but it has many galaxies. The Helix is about 700 light years away (Wiki) and is a planetary nebula. Its size is a result of its closeness. Most planetary nebulae are further away than the Helix.
This shot is a stack of 31 x 5 min shots. (1600 ASA -- all shots at VV were at 1600). Flats, darks, bias.
Processed via DSS, Lightroom, and Photoshop. This is a crop of the approx. 50% of the area of the original. Couple of nitpicks: 1) Target is a little small for a 80mm scope. 2) The hints of red circular nebulosity to the lower left of the nebula really speak to the need for doing this target as a composite (like M31) by doing a series of 15-20 minute exposures as well.
