Albireo – now it’s officially NOT a binary
Everyone’s favourite double star is now officially not a binary system according to the latest GAIA data release. This is just to show that I don’t care – it’s still the best.

Wide angle test – Orion
DIY wide angle mount using old ETX90EC mount. Horrible vignetting caused by IDAS filter in front of lens, but could be removed with flats. Proves the drive works though. Using an old fixed 135mm film lens (approx. 80mm equivalent).

Discovered 14 Aug 2013 by Koichi Itagaki of Yamagata, peaked at mag. 4.5.
It’s about 13,000 light years away. Was originally quite blue but is now much redder – this is what sometimes happens as novae evolve.
From Sky & TelescopeThe nova was discovered by Koichi Itagaki of Yamagata, Japan, in an image taken at 14hhUniversal Time (2 p.m. EDT) on August 14th. It was not present in a photo that he took the previous day. Here is the announcement from the IAU’s Central Bureau for Astronomical Telegrams. The star was apparently 17th magnitude before erupting, so it brightened roughly 100,000-fold to its peak on August 16th.
A classical nova happens in a special kind of tightly-orbiting binary star system: one where a relatively normal star pours a stream of hydrogen onto the surface of a companion white dwarf. When the layer of fresh hydrogen on the white dwarf’s surface grows thick and dense enough, the bottom of the layer explodes in a runaway hydrogen-fusion reaction — a hydrogen bomb in the shape of a thin shell roughly the size of Earth. The underlying white dwarf remains intact, and as new hydrogen builds up, the process may repeat in a few years to tens of thousands of years.
