Year of the Comet

If there were such thing as an Astronomical Calendar, last year would have been the “Year of the Sun” following the total solar eclipse, the annular eclipse and the Transit of Venus. And this year it would be the “Year of the Comet.”

Comet C/2011 L4 (or just Comet Pan-STARRS), was discovered by the Pan-STARRS 1 telescope in Haleakala, Hawaii, and first made an appearance in the southern hemisphere in 2012. People were treated to a spectacular show as the comet neared an estimated brightness of around +1. People in the northern hemisphere enjoyed Pan-STARRS in March 2013. Although it’s still visible, it’s not nearly as impressive as it has been.

But in 2013 we are going to get a very special treat. Coming soon to a sky near you is Comet C/2012 S1 (ISON), which most people simply call Comet ISON. Discovered in September 2012. There is some speculation that this could be the best comet in years.

Of course, we all love seeing comets, and we also know that there’s a lot more detail available to comets than what we can see with the naked eye. So what about using iTelescope to image comets? It can be done.

And if there’s anyone who knows about imaging comets, it’s iTelescope member Rolando Ligustri who lives in northeastern Italy. I asked him a few questions about his experiences and how he got into imaging comets. 

When did you start becoming interested in astronomy?

When I was young, I saw men land on the moon and fell in love with space immediately. I received my first telescope in 1973. It was a small but excellent refractor: a 76/910. With it I began to observe the sky. My first target was the Pleiades, and then Saturn. When I first saw it, I was overcome with emotion: it was a three-dimensional planet!

Then I continued to observe the sky. I only stopped when I was an officer in the Italian Navy. In 1986, I bought my first real telescope for astroimaging — to photograph Halley’s Comet! In 1995, I bought my first CCD and after that another, I imaged hundreds of objects and dozens of comets. 

When did you start becoming interested in comets?

My interest began with the observation and photographing of Halley’s Comet. It was too bad that the 1986 passage wasn’t very bright. Then, with the creation of the CAST Observatory (MPC235) [an observatory in Italy], I began to study them more and more. As of today I have photographed almost 150 comets, and thanks to remote telescopes like iTelescope, I have had several of my photographs appear as an Astronomy Picture of the Day (APOD).

Which iTelescopes do you use to image?

There is no one telescope in particular that needs to be used for photographing the comets. Every set-up in the various sites around the world can go well with astrophotography — you just need to know what you want to achieve (beautiful photograph or scientific measurements) and the size of the target. In principle, the telescopes with short focal length are useful for creating beautiful images; ones with longer focal lengths can be used for searching out details inside the coma or in the first part of the tail in addition to measurements of position and light. What is important is to always pay attention to the resolution of the telescope and the movement of the comet. If you’re making measurements, 1 pixel of blur is acceptable. However, if you’re just imaging for the pure beauty, it can move 6 to 8 pixels, which you can fix in post-processing.

 Can you give advice to those looking to image comets?

As I said above, you first need to decide the field of view, both in terms of the size of the comet, or for any deep sky objects nearby. A photo of a comet must always be studied, even for how to frame it. Once you decide how to frame it and know the resolution of the instrument as well as the apparent speed of the comet, you need to determine the maximum exposure.





Cloudy Nights

Those Cloudy Nights

So you’ve joined iTelescope, and now you are ready to take images of some amazing, mind-blowing target. You log on and . . . it’s cloudy. At all three sites. 

As the past few weeks have shown us, it happens. After all, it’s spring (fall in Down Under) and clouds are just part of the changing seasons.

Is it a waste of time? No. This is perfect. This is the prime time to lay out all your targets.

You may know what image you want to take, and you know what you want it to look like, but how do astrophotographers get those stunning images we see and admire so much? How can you get similar results? One word: planning.

Let’s say you want to take an image of the Carina Nebula. First thing is, you have to know which telescope you want to use.

There are a couple of ways to figure out your field of view (FOV) so that you’re not imaging just part of a galaxy or nebula. I recently purchased SkyX ($144 USD), but I was using Stellarium — which is free — to give myself at least an idea of the area a target would fit in.

That’s the first step. Now, how to figure out how many images you need to take.

When I first tackled astrophotography, I knew almost nothing of CCD imaging. But I did know that I had to stack images. Stacking (for those new to astroimaging) is when you take multiple images and use software (usually astronomy-specific, as opposed to something like Photoshop) to actually put them one on top of the other. Why? Because a) you have a better chance at cancelling out noise [though darks make ALL the difference] and b) because you can pull out more detail with more images one on top of the other. So, in theory, the more images you take of your target (called “lights”) the better and sharper the image. 

What you can do on these cloudy nights is figure out how many lights you’d like to take of your target.

The next thing you can do is figure out the timeframe for your imaging run. Of course, once you determine your target and enter it into your imaging run series, iTelescope gives you the time it rises and sets, as well as its transit, etc., but it’s always good to take a look at sky software to see where exactly your target will be. As well, this is a perfect time to see where the moon is — if it’s up at all (see my last post for how you can use this to your advantage).

The Carina Nebula in narrowband

So don’t let those cloudy nights get you down. Take the time to pick multiple targets and research. Because this is how astrophotographers do it. Time and patience  . . . and planning.

Remember . . . use those cloudy nights!

a)   Plan which telescope you’re going to use

b)   Frame the target

c)   Decide how many lights you want or can afford

d)   Figure out at what time you’d like your imaging run to start
