Astronomy / Space My Pleiades pic...

[HailVectron]

Took this a few years ago, but there have been a couple of posts about nebulae and Pleiades, so I thought I'd share... Pleiades does have a 'nebula', but its just reflective, dust only...

Very nice indeed.

I want the ceiling of my bedroom like this

I watched that BBC4 doc about stars that is mentioned in this board actually, and they said that the first dinosaurs wouldn't have seen these stars, because they hadn't been born yet! So I'm assuming all that dust around them will end up forming into the planets over the next few billion years...

Very nice! It's hard to do such a good job on the nebulosity.

Amazing work. You got good detail out of it and your tracking is almost perfect. What equipment did you use and what were the exposure times ?

The cluster is dominated by hot blue and extremely luminous stars that have formed within the last 100 million years.

Dinosaurs evolved within a single lineage of archosaurs 232-234 Ma (million years ago) in the Ladinian age, the latter part of the middle Triassic.

I tend to be a bit sceptical about the BBC these days, but a quick check shows that it was actually correct.

Thanks for the info. I never realised that and thanks for the great Picture.

Somehow it puts me in mind of the Phoenix Asteroid from the film, Dark Star.

A long time ago now, but IIRC it was an 80mm ED refractor with a Canon 300D. 6 or 8 minute frames (can't remember how many), all on an autoguided EQ6 mount.

I must resist the urge to start browsing equatorial mounts on the internet...

Cool, I got a Skywatcher ED 80 and a Canon 1000D, but haven't modified the camera with a UV pass sensor. I wanted to get an HEQ 5 Pro mount to replace my old EQ-5 one.

I don't think that could have been taken with a refractor due to the diffraction spikes on the stars. Almost certainly a Newt. Lovely pic though.

(For non-astronomers, the spikes on the stars are caused by the four mounting posts (spider) of the secondary mirror on a Newtonian reflector. Refractors don't exhibit this because they use lenses, nor do Schmidt Cassegrain or Maksutov scopes because the secondary mirror is mounted on a glass plate)

It can if you use a Photoshop plugin to put on diff spikes

My 10" newt doesnt have the FOV to get the whole Plaeides in, so I'm pretty sure it was my 80mm ED...

 

[EponymousCowherd]

Odd, isn't it, that star field pics look so much better with diffraction spikes. Never knew you could use Photoshop to add them (use Gimp myself)

Dark skies ;-)

Hailvectron, that's lovely.

Knocked my picture of Merope (below) into a cocked hat! Although you can certainly see where my little field of view has fallen!

Cheers,
