My next scope is going to be a Vixen VMC200L Catadioptric OTA

Basically - Yes - as far as we know. There are of course subdivisions
The same damn subdivisions that got Pluto demoted from being a planet.
I'm still pissed about that,

OT:
Are you pissed about Ceres too? It was mistakenly called a planet for a while too when it was discovered but then we saw sense. There is only one argument for keeping Pluto as a planet, sentimentality.
Back to the topic, I have to say that's pretty bloody cool, and way more deserving of a fan-fare than that last announcement.

Maybe not..
This is the remanant of a suspected Red Supergiant (V838 Monocerotis)gone nova (not supernova). Still, as you can see from the time frame of the stills, you don't have to wait too long to see results.

Guess we will have to come back in 100 million yrs to see what kind of nebula if left behind.

Won't be much left to look at in 100 million!
Look at the crab nebula and the nebula around 1987a.
I've a small animation in the archives here somewhere of the difference in the crab nebula over 50 years - you don't need to wait long for these things.

More info:
www.cnn.com/2008/TECH/space/05/21/star.explosion.ap/index.html
Astronomers were observing SN 2007uy when they saw that SN 2008D had begun to explode.
The supernovae are in the spiral galaxy NGC2770, about 100 million light years away from Earth.

WOW Seanie. I had no idea that V838 had gone from that to that in 2 yrs.
When i spoke of 100 million yrs..............i was refering to the distance of the SN in LY's from earth. So a newly "formed" discovered SN that far us........we wouldnt see the light from it for 100 million yrs.
I guess DS telescopes change all of that............and we see it almost the instant it happens?.
