The Power of Stacking Images


This was taken on an entry level DSLR with a 10 mp CCD sensor. Which is far from a great camera by today's standards.

The lens used was a very old kit lens from my old Pentax ME-F a 35mm 1.7

I was basically testing the lens performance at imaging stars, the night was not very good for astrophotography either, there was poor visibility and periodic clouds.

In the near future I will be doing another "stacking" of images with a bit longer (80mm) focal length using just my dslr, a regular lens, and a tripod.  I will make another post with the resulting image to show the power of stacking even more.

Settings used
Exposure - 15 seconds
Iso - 800
Lens - f 2.8
2 second delay timer to minimize shake

I took 5 images and stacked them using a free program called Deep Sky Stacker
and did some further processing in Photoshop.


I've also labelled the more known stars and some areas that contain some of the better known deep space objects. You can even see (faintly) the Orion nebula.





This image is several images stacked around the Orion Nebula, Running Man Nebula, and The Horsehead and Flame Nebluas.  The more images that you stack the more information will be in the stacked image.

How to Make the Stars POP!

If there is one thing I've learned about processing night shots.

There are as many opinions and as many ways to do things as there have been sunrises! With that being said, I thought I'd share another technique that I've employed a couple of times

This technique is very simple and very effective.  The nice thing about my tutorial is that I show you how to do it yourself.  I’m not a fan of “presets” that take the adjustment factor out of your hands.  I’d rather show someone how to do it for themselves.  That way you can actually expand your knowledge and learn to help yourself and others around you.

In this particular “How to” we will be increasing the size and brightness of the larger stars.  This technique can also be used to bring out the natural colour of the stars or any other adjustments you may want to use.




Like most of my tutorials, I take the approach that you have a basic knowledge of photoshop.  If you don’t and need some further assistance with this tutorial, please…

How to Reduce Star Trails

600/(18x1.5)= &%*@!*$

So, you either didn't follow the 600 rule, you're bad at math, or you made a mistake! Now you've got a shot that you absolutely love but the stars look like eggs, or worse yet, they are mini trails!
Don't scrap that photo without at least trying this little know trick of the trade.
In this tutorial I will teach you how to remove small trails to make your stars look crisper.
****  Does it always work??  Nope ****
But heck, why not at least give it a go before deleting that photo.
The Original Image
Here is my original image opened in Photoshop.  You will notice that the stars look like mini trails. This particular image was exposed for 43 seconds (23 seconds longer than I usually expose an image).

The Original Image Magnified
Here you will notice how the stars are trails and not as crisp as they should be. Normally most people would throw this image out.

Stars Layer Selection
Start off by selecting the sky.  I used the marquee tool but you can use an…

How to stop camera lens fog

How to stop camera lens fog
Astrophotography, Landscape Astrophotography, and just plain old Night Shooting are difficult enough.  Using the right lens, setting the ISO correctly and getting the exposure time correct are all issues that plague photographers shooting at night (and other times of day).  
Never mind the fact that fact that "playing" in the dark has several dangers, from wild animals, to wilder people, and even police that thing you're up to no good.  Mother Nature figured she'd have a go at you also. If you have ever gone out shooting night scenes, wide-field astrophotography, or landscape astrophotography, you've probably experienced the dreaded lens fog.
What causes lens fog
The easy explanation To explain this issue in simple terms, your camera's lens will fog most times when the lens is colder than the air surrounding the lens.
The more in depth explanation When the air near the lens is cooled by the lens, the relative humidity of the surrounding a…
