Great photo but being dense what am I looking at?

It was over 200 ,40 second exposures with the camera cooled to -15. Sleeping on the job will certainly be considered next time Im outback..

Its M42 (AKA) The great Orion Nebula. A Stellar nursery located in the sword of Orion to the unaided eye looks like a fuzzy star. under exposing the outer nebulosity would reveal a cluster of young stars in the bright central region.

Are these what we refer to as 'stars'? The sun I believe is basically a nuclear reaction with it's gravitational pull all that prevents burning matter from spreading and frying us. Are stars the same?

Simplified, yes..., you can see in that image where the gases have collapsed under gravity into the central area to coalesce into new stars, The nebula itself is estimated to be around 24 light years across, put into perspective our sun is 20 light minutes away , roughly..

A bit of cloud and moon dodging last night, but still managed 77 x 40 second images of the Fornax Cluster... Many galaxies in this image, Elliptical, they look like fuzzy stars, spirals, barred spirals and irregulars ... Interestingly the cluster is approximately 65,000,000 light years away, therefor the light we are seeing now left there when the dinosaurs were wobbling around the place... Look carefully how many can you see ?...

Santa came early, a new tracking mount and carbon fibre tripod . It can handle 15kg without a counterweight, does not need to be balanced, and slews at 6 degrees a second. Amazing really how technology advances. Anyway, now I,m guaranteed clouds or a bright moon, right through until xmas.
