The best interval would depend upon the focal lengtth and aperture of your lens.  I forgot to mention f/2.8 in my example with a 14mm lens.  Experiment with it.  That's the fun part of it.  Expect to have several false starts, too.  A lot of the exposure setting also depends upon how much light pollution is at your shooting location, too, both on the ground and in the atmosphere.  Use a lens hood, wihch goes without saying.

 

[EDIT] Check out this thread....

It is a link to a great article!


Thanks! I have a f/1.8 50mm lens I was thinking about trying. What would be a good lens hood? Can I get one on Amazon?

 

EDIT: I just saw that each lens has their own hoods. I thought there would be a universal hood that would work on almost any lens. **bleep**.....I'm gaining more equipment by the day!!

Exactly.  If your remote has an intervalometer, then set it up to take multiple long exposures back to back to back.


Yep...thats what I'll do!

The hood on the EF 50mm f/1.8 STM is small, that it is almost not worth buying.  It is about 1/4 inch tall, if that much.  I bought one, but I cannot remember where.  May have been from B&H.  I avoid the Amazons and Ebays for anything, except for books.

You really don't need a hood for the 50mil.  As a matter of fact, some telescopes don't even have tubes around them.  A word about the 50mill. it isn't all that great and it is pretty long for big or deep sky.  It probably will make 'star trails' all by itself in just one shot!

 

You really need to get in contact with Tim Campbell.  These guys and me can give you suggestions but he can tell you exactly how to do it.  Try sending him a PM if he doesn't respond or see this thread.

A lot of Canon stuff. Along with, a lot of other stuff.

I knocked this shot out when I was shooting the moon (heh!) with my Tamron 150-600.

It was shot with a T3i at f/5, ISO400 and 15 sec exposure and 150mm focal lengthIMG_3688.JPG

It was shot in the middle of Albuquerque, not the darkest of cities, but not that bright either.

Nothing special, but it kind of fits here so I thought I would post it. You can barely make out Orion.

I must give you a salute.  If that is one of your first efforts,then it looks 1000% better than mine, shot in light polluted NYC.

 

I have two freeware image stacking applications, RegiStax 6 and Deep Sky Stacker.  The latter is designed for astrophotography.

No, you really don't need a lens hood for the "nifty fifty" 50 mm lens.  But, a lens hood might be useful for a wider angle lens, like something 20mm or less, with a wide aperture.

 

There is a pretty good description and explanation of the "Looney 11 Rule" at Wikipedia, too.  But, Tim Campbell has several posts, probably dozens, that explain it more succintly than Wikipedia, though.  His user name is "TCampbell".  Do a search for some of his posts and threads.

Probably my third, but thanks.

 

I feel guilty because here in NM there is no shortage of dark and clear skies.

You feel guilty because your state hasn't indulged itself in universal light pollution? Somehow that sounds backwards.

There is actually so much air and light pollution in Manhattan that you cannot see any stars, not even on a clear night.
