NGC 1491
In the Sharpless catalogue as SH2-206. Sometimes called the Fossil Footprint Nebula.
This is an emission nebula just under 11,000 light years away in the constellation of Perseus.
HII regions of space such as this are formed when the ultraviolet radiation generated by hot stars ionizes the surrounding gas, causing it to glow in the visible light.
You often hear tell that stars are made from dust & gas, well the dust is also affected by this radiation too. The radiation makes the dust glow in the infrared light.
Boring techie bit.
Skywatcher quattro 8" S & f4 aplanatic coma corrector
EQ6 R pro mount guided with an Altair 50mm & Altair GPcam
Canon 450D astro modded with Astronomik CLS CCD EOS APS-C clip filter. Neewer Intervalometer used to control the exposures.
70 exposures of 80 seconnds each with the best 75% stacked together with calibration frames.
Software used, PHd2, DeepSkyStacker, StarTools and Affinty Photo.
