It's getting near the end of my Riccardi-Honders telescope three-year run.
It is moving on to a new user and I to a Planewave 20" CDK.
For the last week or so of use, my plan is to image as many bright narrowband targets as time and weather will allow. These are oldies but goodies. Here is the first one. This images combines all the H-alpha data from the last couple of years including the other night.
Note those "pillars" in the lower portion of the image. They will be an interesting target for my new 20" CDK when 7822 comes around next year.
Here is what the
Wiki says about NGC 7822.
NGC 7822 is a young star forming complex in the constellation of Cepheus. The complex encompasses the emission region designated Sharpless 171, and the young cluster of stars named Berkeley 59. The complex is believed to be some 800–1000 pc distant,[5][6] with the younger components aged no more than a few million years.[5][6] The complex also includes one of the hottest stars discovered within 1 kpc of the Sun, namely BD+66 1673, which is an eclipsing binary system consisting of an O5V that exhibits a surface temperature of nearly 45,000 K and a luminosity about 100,000 times that of the Sun.[5] The star is one of the primary sources illuminating the nebula and shaping the complex's famed pillars of creation-type formations, the elephant trunks.[5][7][8]Eric
