Sooner or later within the pictures journey, each photographer entertains the potential for moving into astrophotography. However, for a lot of inexperienced persons, it’s a scary proposition due to two main misconceptions.

How to Take Pictures of Stars: A Beginner’s Guide to Astrophotography

False impression One

The gear for astrophotography is prohibitively costly and, consequently, is out of attain for many inexperienced persons and hobbyists.

This was true even 5 to seven years in the past when a mixture of cameras able to producing high quality pictures at excessive ISO paired with a quick and broad angle lens would price you wherever from $4,000 to $5,000.

However, lately, issues have drastically modified. Speedy advances in sensor know-how enable us to make use of entry degree cameras from practically any producer to {photograph} the celebrities. Additionally, third celebration lens producers, principally these from Asia, lastly achieved the right steadiness between the standard of lenses and worth.

We are going to handle the gear it is advisable {photograph} the celebrities in nice element within the Gear part however, it’s value mentioning now that you could have all of the gear needed for astrophotography for below $1,000.

False impression Two

The second false impression is that the strategy of photographing the celebrities is simply too complicated for many inexperienced persons. That is utterly false. The astrophotography course of is definitely quite simple and simple. However, what makes the method extra time consuming than conventional panorama pictures is preparation and scouting.

What’s Astrophotography in Easy Phrases?

Once you have a look at the sky at evening with a unadorned eye, you see solely the brightest stars and, even then, the brightest are nonetheless very dim.

Astrophotography permits us to amplify the brightness of the celebrities by conserving the digicam’s shutter open for an extended time period, which lets the digicam sensor seize way more gentle than what’s doable with our eyes.

Because of this, astrophotography permits us to {photograph} stars that aren’t seen to the bare eye.

Gear

Though location is crucial a part of the astrophotography equation, there may be clearly no method to {photograph} stars with out the right gear.

There are 5 items of apparatus you want, however solely three are important.

1. Digital camera

You want a digicam with handbook controls that may produce first rate, high quality pictures at ISO 1600-3200. The excellent news is that the majority fashionable cameras already fall below this class.

2. Lens

The Milky Manner is unfold extensively throughout the sky and is a really dim topic. Due to this, you want a large and quick lens.

If you wish to shoot the entire Milky Manner in a single shoot, you will want a lens wider than 24mm on a full body digicam or 18mm on APS-C.

For the aperture, f4 is nice, f2.8 is nice, any lens with aperture sooner than f2.8 is superb.

3. Tripod

That is most likely crucial a part of the whole astrophotography setup. When utilizing a shutter pace of round 20-30 sec, even the slightest motion of the digicam will break your pictures. Because of this it’s not sufficient to make use of simply any tripod, it’s important that it’s rock stable.

4. Headlamp

That is an non-compulsory piece of apparatus that may be changed with any commonplace flashlight.

5. Distant Shutter Launch

The distant shutter launch is one other non-compulsory piece of apparatus. It may be changed by the two sec delay performance on most cameras.

Kevin’s Gear

Each the Nikon D810 and Canon 100D can produce nice high quality pictures even below ISO3200 however, after all, the Nikon D810 is best.

Viktor’s Gear

I’ve a minimalistic astrophotography setup.​

I take advantage of a Sony a6000 digicam and a Rokinon 12mm f2.0 prime lens. I take advantage of a Feisol tripod which, by design, doesn’t have a middle column and is extremely regular even in windy situations.

Discovering the Milky Manner and the Darkish Sky

Once you begin studying how you can {photograph} the celebrities, the Milky Manner is often the primary and hottest object to shoot.

Nonetheless, it may be a problem to search out the Milky Manner at midnight sky. Though all of us stay within the Milky Manner galaxy, most individuals by no means see it.

Earlier than going into the technical points of capturing the Milky Manner, it is necessary that you just first know how you can discover it.

Seasons of the Milky Manner

Though the Milky Manner is at all times throughout Planet Earth, you see completely different elements of it relying on the completely different seasons and your location.

The most effective months to shoot the Milky Manner are at all times from March to September. Throughout this time, you’ll be able to {photograph} the Milky Manner’s shiny galactic middle.

You can even shoot the Milky Manner all through the remainder of the yr as a result of, even with out the galactic middle, you’ll be able to nonetheless create fascinating pictures.

Darkish Sky

One other issue that instantly impacts astrophotography is the darkish sky. The Milky Manner is dim by itself so even the tiniest trace of sunshine could make it much less seen and more difficult to {photograph}.

Gentle air pollution and moonlight are the 2 primary gentle sources that have an effect on astrophotography essentially the most.

Gentle Air pollution

The place there are individuals, there may be gentle. At evening, that is known as gentle air pollution. Due to gentle air pollution, it’s nearly not possible to {photograph} the celebrities in the midst of town.

The easiest way to find areas with minimal gentle air pollution is to test this free on-line useful resource generally known as the Gentle Air pollution Map. Yow will discover it right here: http://www.lightpollutionmap.information/

Moon Section

One other supply of sunshine that impacts the darkish sky and photographing the celebrities is the moon. When there’s a full moon, it’s nearly not possible to seize any stars.

The most effective apply is to shoot throughout a brand new moon or to shoot earlier than the moon rises or after it units. By timing the moon excellent, you’ll be able to make sure that your digicam is ready to seize the best particulars of the Milky Manner.

To test the moon section, you’ll be able to go to these web sites:

Kevin’s Scouting Routine

I usually test the moon section and climate report first. If the day is nice for capturing Milky Manner, I’ll then test StarWalk 2 to see what time I ought to exit. Then, I’ll head to some panorama pictures group on Fb and in addition 500px to search out some new location. If I discover an fascinating panorama location, principally dawn and sundown spot, I’ll then test Google map to see if the place faces the Milky Manner or not. 

I wish to go to places that no individuals have shot Milky Manner earlier than to present myself a problem. If the climate turns instantly cloudy, I nonetheless have an opportunity to shoot an incredible dawn or sundown.

Viktor’s Scouting Routine

My scouting routine begins with the usual set of instruments I take advantage of for my journey pictures planning. I take advantage of Google MapsGoogle Earth, and 500px.com to search out fascinating places. I praise them with an android model of Star Stroll 2 when scouting particularly for astrophotography.

Focusing

The primary problem of capturing the right picture of the celebrities is to get the celebrities as sharp as doable. Focusing turns into essentially the most important a part of the method. However, everyone knows how tough it’s to focus in full darkness.

It sounds easy—you at all times focus to infinity. In concept, all it’s a must to do is flip the focusing ring all the way in which to the correct. In actuality, nevertheless, this can focus past infinity on most lenses, which is totally illogical from a physics perspective. Focusing past infinity will produce out-of-focus and tender stars.

Listed below are a number of completely different strategies you should utilize to get the celebrities in focus and sharp:

  • Whereas scouting throughout the day, focus after which make marks in your lens as reminders.
  • Know precisely the place infinity is on each lens you personal. Discovering infinity might be extra problematic on a zoom lens since, for various focal lengths, infinity will likely be somewhere else.
  • Take a number of check pictures and test the sharpness of the celebrities after each shot. Maintain adjusting the main focus till you’ve the right settings.

Viktor’s Focusing Routine

I’ve a really simplified focusing routine. I’ve just one lens devoted to astrophotography – a handbook prime lens. I do know precisely the place infinity is on the lens however, to make sure the right shot every time, I made a small mark on the lens as a reminder.

Kevin’s Focusing Routine

I take advantage of a special focusing method with my 14-24mm zoom lens. I swap the digicam to a stay view, zoom in to a most, discover a shiny star, and deal with it.

Capturing Approach

As I discussed earlier, capturing is likely one of the best elements of the whole astrophotography course of. Why? Since you don’t have a lot room or flexibility to experiment with a wide range of completely different settings.

Let me clarify.

The sky is darkish and the celebrities are dim. You utilize the widest aperture doable to seize that restricted gentle.

The earth is continually shifting, which limits your alternative of shutter pace values. When you transcend a 25-30 sec shutter pace, the impact of star trails turns into apparent which, in flip, makes the celebrities tender. I personally want to by no means transcend a 25 sec publicity.

This leaves us with the one parameter we will mess around with – the ISO.

How to take pictures of stars - Shooting techniques

When I’m on location, I’ve my digicam in M (handbook) mode. I set the aperture to f2.0 (the widest worth on my lens), the shutter pace to 25 sec, and the ISO to 640. Then, I take a check shot. I preview the picture and analyze the histogram. Most often, these settings produce an underexposed picture so I begin growing the ISO and analyzing the preview after every shot till I’ve a correctly uncovered picture. From that second on, I preserve capturing with the identical settings for the remainder of the evening.

Associated: Low Gentle Pictures Suggestions

The shutter pace of 25 seconds just isn’t a great worth. To get sharper stars, I want to shoot between 15 and 20 seconds, however I additionally must steadiness this with the ISO worth by not going past ISO3200. I discover that even ISO3200 is a bit an excessive amount of for the Sony a6000 APS-C sensor.

Maybe crucial facet of capturing is that you just at all times shoot in RAW.

Composition in Astrophotography

Even if in case you have all of your gear prepared, you already know precisely the place to search out the Milky Manner and you already know precisely what settings to make use of to {photograph} the evening sky, this doesn’t routinely assure that it is possible for you to to supply fascinating images. Astrophotography isn’t any completely different than another sort of pictures as it’s not sufficient to have all of the technical points in place. The creative half at all times comes into play.

When you merely {photograph} the sky, your pictures will seem like sky charts and, whereas they might be technically sound, they’ll seemingly be boring. It is advisable to discover a method to deliver different components in addition to the sky into your composition. The weather of a scene can function reference factors for the viewer to emphasise the dimensions of the sky.

When you’re capturing at evening in pitch black, it’s usually tough to visualise your potential compositions; typically, it’s not even doable to see the objects of the scene.

I like to recommend addressing the composition facet of your astrophotography shoot throughout the day if you find yourself scouting the scene. You’ll be able to take your time with out speeding to evaluate the composition. Once you return to the situation at evening, composition turns into a easy technicality – a easy strategy of triggering the shutter.

Enhancing in Astrophotography

The enhancing a part of astrophotography isn’t any extra difficult than typical panorama enhancing. The one exception is that you just at all times must take care of extreme noise.

Right here is a straightforward define of enhancing in astrophotography:

Balancing Publicity

Earlier than you begin making use of any results, you first have to steadiness and alter the publicity. Once you take footage of the sky, they often come out a bit underexposed. Due to this fact, you need to enhance the publicity of the picture till you attain a correctly uncovered starry sky with the Milky Manner.

White Steadiness

The subsequent step is to regulate the white steadiness. Once you take image of stars in AWB (auto white steadiness) mode, the digicam usually produces a really heat toned picture.

Since pictures of the evening sky are naturally very darkish, it’s tough to determinate if the white steadiness is appropriate or not. However, you’ll be able to at all times use a technique generally known as the “Excessive Saturation Methodology” to regulate the white steadiness.

Excessive Saturation Methodology

First, enhance the vibrarance and saturation all the way in which as much as 100. Your picture will develop into oversaturated and have some laborious coloration transition.

Don’t fear, you’ll be able to change it again later.

Noise Discount

Capturing the evening sky at a excessive ISO (1600-3200) sometimes ends in a picture with extreme noise. By growing the distinction and saturation throughout the enhancing course of, you find yourself amplifying the digital noise much more.

Begin decreasing the noise through the use of the Particulars panel in Lightroom. When you discover it’s not doable to attain the specified outcomes, you almost certainly want to make use of a devoted noise discount program.

Kevin’s Favourite Noise Discount Program

Noise discount is an important a part of astrophotography. 

The quantity of noise discount is completely different within the starry sky and the foreground. I take advantage of Nik Outline to get the job carried out. It permits me to create a layer masks to present a special diploma of noise discount in a special space.

Viktor’s Favourite Noise Discount Program

I take advantage of Topaz DeNoise from Topaz Labs every day. I run noise discount with DeNoise on each single picture I edit. It turns into essential when enhancing astro pictures.
