iiapy masterclass enhancing ic 1318, the butterfly nebula

The ‘dark art’ of processing is not an exact science. There are so many techniques you can use and they’re constantly evolving, which means that a lot of your choices are as much down to personal taste as technical know-how. Here I'll describe the processing techniques used on my image of IC 1318 which was captured and processed during September 2017. I was very pleased with the results, so hopefully some of the methods I used will prove helpful for you. IC 1318 is a beautiful and interesting area surrounding Sadr (Gamma (a) Cygni), with fascinating details. The framing of the photograph was carefully chosen to include the central dust lane (running from bottom right to top left) and to exclude Sadr (just off frame to the left). At mag. +2.2, the…

orion’s salty star

Wherever stars are forming, astronomers have come to expect a disc of material to form too. Such discs eventually provide the site and the raw material for planets to grow, but they have another important role that starts long before that. A protostar grows through accreting material from the disc. But there are powerful winds that sweep up material from the disc, taking it away from the growing star. Eventually this removal of material brings a halt to the accretion process. Or at least, that’s what we assume. It’s hard to actually observe discs while stars are forming, especially for the most massive specimens where such a disc might exist only while the protostar is very young. To peer into the mysteries of star formation, astronomers normally turn to what’s known as…
