An edge on view makes the unobstructed magnitude determinations
(if not the very observations) of Cepheids, Type Ia Supernovae
and many other standard candles extremely difficult.

Can't trust that shifty red-shift ....

Agreed,
I'll hold this end of the measuring tape while you take the other end to the edge of that bad bouy and well settle this distance problem :wink:

What a lovely picture; thanks for sharing it!

[b] Explanation: [/b] Magnificent spiral galaxy [url=http://www.seds.org/messier/xtra/ngc/n4565.html]NGC 4565[/url] is viewed edge-on from planet Earth. Also known as the [url=http://apod.nasa.gov/apod/ap990617.html]Needle Galaxy[/url] for its narrow profile, bright NGC 4565 is a stop on many telescopic tours of the northern sky, in the faint but well-groomed constellation [url=http://www.dibonsmith.com/com_con.htm]Coma Berenices[/url]. [url=http://www.stargazer-observatory.com/4565-ag.html]This sharp, colorful image[/url] reveals the galaxy's bulging central core cut by obscuring [url=http://apod.nasa.gov/apod/ap070729.html]dust lanes[/url] that lace NGC 4565's [url=http://apod.nasa.gov/apod/ap100225.html.html]thin galactic plane[/url]. An assortment of other galaxies are included in the pretty field of view. Neighboring galaxy NGC 4562 is at the upper right. NGC 4565 itself lies about 40 million [url=http://chandra.harvard.edu/photo/cosmic_distance.html]light-years[/url] distant, spanning some 100,000 light-years. Easily spotted with small telescopes, [url=http://www.cloudynights.com/item.php?item_id=1059]sky enthusiasts[/url] consider [url=http://www.noao.edu/outreach/aop/observers/n4565.html]NGC 4565[/url] to be a prominent celestial masterpiece [url=http://apod.nasa.gov/apod/ap080419.html]Messier missed[/url].
