M3 (ou NGC 5272) est un amas globulaire situé dans la constellation des Chiens de chasse à environ 33 300 a.l. de la Terre3. Il a été découvert par l'astronome français Charles Messier en 1764. La magnitude apparente de cet amas est de 6,3, celui-ci est donc situé juste au-dessus de la limite théorique de visibilité à l'œil nu. (Source Wikipedia)

I finally got my equipment working as it should; not entirely happy with the image but pleased to grab something for a change. The next job is clean the optics; the contamination was very evident in the flats.
Messier 3 (M3) is a globular cluster located in Canes Venatici's constellation, the Hunting Dogs. It is one of the brightest, largest globular clusters in the sky. M3 has an apparent magnitude of 6.2 and is approximately 33,900 light-years distant from Earth. It has the designation NGC 5272 in the New General Catalogue.
M3 contains an estimated half a million stars. The brightest stars in the cluster are of magnitude 12.7, and the average brightness of the 25 brightest stars is 14.23 mag. The overall spectral type of M3 is F2. The cluster has a total mass of about 450,000 solar masses.

Quito is a somewhat iconic road, winding its way through Los Gatos near the Saratoga border. It's known for its beauty -- slow, graceful curves, and large overhanging trees -- and the high price ZIP code it passes through.

My new M3. This is based off of Allied Bricks' and Brickist's design. Thanks to them. A side note is that I took apart my M10 to build this. I didn't really like the size and needed the parts. Thanks for taking a look.

In order to keep bizzy I picked up my old telescope, essentially an objective of 2000mm focal distance (and a diameter of 200mm). After several sessions, and a lot of learning and calibrating of the scope, this is my temporary best result of the well known globular cluster M3.
To be continued...

Über den M Basisversionen rangieren als Leistungsmodelle die Competition-Varianten mit weiter geschärfter sportlicher Dynamik. Darüber sind als Sondermodelle CS-Versionen angesiedelt, die sich durch technisch besonders innovative Komponenten auszeichnen.
Above the basic M versions are the Competition variants, which are high-performance models with even more sporty dynamics. Above these are the CS versions, which are special models and are characterized by particularly innovative technical components.
EDIT: fixed the striping with better darks :)
M3 Not much I could do with the vertical striping :( Not sure why this occurred but maybe not enough dithering or funky temps as the weather was warmer (45F)

M3 Globular Cluster on the southern edge Canes Venatici is a beautiful object. This is my first image using the new QYH168C cooled CMOS camera on my 12". I currently do not have a an off-axis guider else I would have had rounder stars. This is really also my first colour photo of a glob so I am very pleased and is good testing for the camera as it is coming to Tenerife and La Palma with me this year.

It's nice if the sun does something when you've gone to the effort of being somewhere to shoot it. This was taken overlooking the Eastern Freeway (M3) and part of the city of Melbourne.
