Deep into M33

[RobertI]

Inspired by Alan Whitman's article in Sky & Telescope entitled "Digging Deep in M33" I turned my lightweight setup (72mm frac @F3.7 + Lodestar mono + SkyProdigy) onto this bright galaxy. As usual with this setup, bloaty stars and lack of fine detail, plus encroaching cloud meant I could only manage 2.5 minutes total exposure time, but some wonderful treasures unearthed nonetheless.

I have annotated the image and described them below. Quotation marks indicate descriptions directly from the article.

• C39 is M33's brightest globular just visible at Mag 16
• NGC604 is "one of the largest emission nebulae known, more than 100 times the size of the Orion Nebula."
• NGC595, 592, 588 are Emission Nebulae, NGC592 showing a double knot of hot blue stars.
• IC132 is "..one of the few bright emission nebulae which areas in M33 that do not contain a stellar association"
• IC142, 143, 133, A112, A127, A128 are large stellar associations

Hope you find it as interesting as I did.

Like all those NGC's you captured
