Simple technique example for beginners.

There has been a dearth of posts here lately, so I am showing again an image
of most of the Eta Carina nebula that I posted here many yrs ago, with the idea that beginners can see what can be done using basic technique, and a scope on an equatorial mount.
Canon 1100D unmodded, SW HEQ5 mount [ the mount make and model is actually irrelevant, as any model that can carry an 8" scope will suffice], 8" SW f/5 Newtonian.
Single frame 90secs, unguided, JPEG, ISO 1600, in camera noise reduction enabled, slight colour saturation, sharpen, and downsize in Irfanview freeware.

I hope the mods won't mind my posting this again.
