exposure stacking

Photo of the Week

This week’s ‘Photo of the Week’ features a beautiful tracked photo of the Pleiades Cluster. Taken by talented amateur astrophotographer Ray Congelosi, this image consisting of 24 one-minute exposures happens to actually be his first tracked photo as well.
 The Pleiades star cluster – also known as the Seven Sisters   or M45 – is visible from almost anywhere on Earth. This open star cluster is one of the closest star clusters in relations to Earth.

Combination of Aurora Borealis and Star Trails created by stacking long exposure/timelapse images together.

It’s been a while since I’ve posted a Milky Way shot on Flickr, so here is one from our recent trip to the PNW. This place is called Secret Beach in the Samuel H Boardman area. It’s no secret though, and it has been heavily photographed in recent time. It’s a really cool beach with tons of sea stacks. We shot into blue hour, and captured a pretty decent sunrise too. Thanks for looking!

Lagoon nebula and Triffid nebula. Not the best image but they were 5-6 degrees above the horizon with light pollution severely affecting the sub exposures! 48x1 minute images stacked in Deepsky Stacker, processed in IRIS (to remove the background) and noise processed in Photoshop.

How can I tell?
Well besides the freezing cold nights, the pleiades are back gracing our skies!
The pleiades, or the seven sisters, are an open star cluster.
One that can easily be spotted by the naked eye!

They are one of the most prominent objects in the skies during winter which therefore makes them a standard imaging target for all astrophotographers.
I took the first image myself with a Canon 1000D.
The image is around 20 or so 30" second exposures stacked together.

Star Trails

Take a moment to think of what that means exactly. The huge mass of Earth that we were born on, grew up on, currently living on, and pretty much have done every single activity on, is floating in outer space and it is rotating and revolving a particular way amongst the vast expanse out there. That is what’s causing the star trails to occur. This big hunk of rock is moving hence the streaking you see with such long exposures. 

A stack of 149 photos at 15 seconds each, f/2.8, ISO 1600. Effectively 37 minutes and 15 minutes long as they’re all combined.
