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.

My Cousin Luke next to a M3 Half-Track near the bridge in Stavelot, we were on a recent trip to the Ardennes, Belgium.
I have had this tank done for about a month now and never gotten around to posting it. This is highly based off of Erik.P's but is all my design.
Updated again. Not only the camo I also changed the turret and the track section a bit.
EDIT: I'm too lazy to mess with the flex tube so don't ask about it.

"Messier 3 is one of the most popular targets among amateur astronomers next to Messier 13, the Hercules Globular Cluster, and one of the most studied of all known globular clusters. It has an absolute magnitude of about -8.93 and a luminosity about 300,000 times that of the Sun. The cluster is approaching us at 147.6 km/s."

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.

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)

Here she is. It's funny, because I barely spent any time on this one, but I'm actually pretty happy with it. Definitely easier to build one in D Bley instead of tan. The part selection was liberating.
Also, quick (or not so, but do yourself a favour and read it) little side rant here because its been on my mind.
When you're building a vehicle out of LEGO that is intended to accurately replicate something that was built in real life (and therefore has an excess of reference photos available, wiki pages dedicated to it, etc) keep a few things in mind.
a) Know what you're actually building. Do some basic homework and understand the difference between an M3 Vs. M5 Stuart, late Jackson Vs. early Jackson, M4A1 Vs. M4A2, etc. Nobody expects anyone else here to be a war historian but I don't think it's asking too much for everyone to do a tiny bit of research instead of just lamely grabbing some techniques from Max, throwing some sort of gun on and calling it a 'Sherman'.
b) Dimensions: this is numero uno in my mind when it comes to the actual construction of these vehicles, yet my feed is constantly filled with vehicles that have proportions that are totally wrong, bogeys that are too large, tracks that are the wrong length and width, etc. Just basic things that if done wrong completely ruin a build.
c) Details: this does not mean some sweet over engineered flex tube basket stuck on the back to make up for an otherwise lackluster build, I mean looking at real photos of whatever you're working on and doing your best to actually recreate the details, or lack thereof, across all parts of the vehicle and within the limits of our medium. Ie if you're working on an M4A1(75) Sherman, include the damn VSS. Do yourself a favour, take your time and don't just throw some wheels on that you saw your favourite builder use on theirs and call it a day while leaving out one of the most important features of the tank.
Hope this helps somebody.
Cheers guys, Lincoln and I may or may not have something fun coming along if we can get our acts together but no promises right now.
M3 & Caffè
Day 1, week 1, month 1 of my new calendrier photographique project.
Based on the French Republican calender, starting on 22 Sept, the 1st of Vendémiaire. Each month is made of 3 x 10 day weeks. Each week I shall use a different camera(s) and select 3 best shots for the week, edit then blog at the end of each 3 months season.
It’s a project I hope to continue for a long, long tme.
And today is day one, using one of my 1950s Leica M3 & 50mm summarit f1.5 lens. #camera #filmcamera #oldfilmcamera
