How to practice deep-sky? Torres In this section, I will give you an outlook regarding instruments and books for practicing Deep Sky. It is subjective and reflects just my experience, but perhaps it can help you to develop your own opinion about what you really need. Instruments I have owned different instruments along 25 years. My first instrument was an old 7x50 binoculars pair that my father gave me one summer. That is how the astronomical bug bit me, looking through the Milky Way at random.
Learn first the constellations and spend at least a year making starhopping. And from time to time, switch off the power, and enjoy the sky by yourself. Even without power supply or star tracking, the LX is a comfortable telescope to find what you want, still in altazimut mode. I have to say that I do it frequently: less parafernalia, and more sky contact makes you more delighted. I also like very much observing with large binoculars. Currently, these are a 25x Celestron SkyMaster pair with a parallel 9x50 finder small picture on the left.
Formerly, it was a 20x80 Zeus binos pair. In combination with the LX, giant binos makes the starhopping process easier, and in addition, the binoculars provide a second perspective in the observed object very worthy.
However, too much parafernalia makes one reluctant to observe. For this reason, I tried to reduce the equipment.
For field work I considered essential a set of two reference books picture on the right and the minimal accessories. The books include photocopies of the original sources, so moisture and deterioration are not so problematic. The field atlases are also photocopies stored into plastic folders see below.
Anyway, loading the car makes one always lazy. So except in situations where you are spending two or more nights, think twice before loading your car with tons of material that likely you will not use. Less equipment fully enjoyed will let in you better memories.
Good sky maps are essential. It consists of 12, maps see the pictures. Frequently you need to know exactly where the fuzzy you are chasing lies to perceive it.
Thus, I usually choose the HB-C left to navigate to the place where my target is located. Then, if necessary, I switch to my map collection left and below to boost the detail and to spot the object. The HB-C provides panoramic views, and usually plots at least a 9 magnitude star near the object, that can be seen in the corresponding one-degree circle.
This is essential: a smaller atlas, such as Sky Atlas , does not guarantee plotting at least one star close enough to the object, and makes more difficult the identification. I have tried the collection for half a year and I can affirm that is the best star atlas I have tried ever. For getting truly functional maps, I prepared an index section listing the objects first by constellation, then by RA, and then by DEC, that allow locating any object in a few seconds.
Each A4 page in the collection contains 54 maps gathered in blocks of six maps each right picture , and printed at dpi.
The main folder contains a selection of the 6, best DSO, and the second, an extension for faint galaxies, galaxy clusters and objects that did not pass the filtering conditions.
As you can see, any of the 12, objects is presented with its basic data and a field of 1 degree centered on it. Just take the atlas you prefer and compare the details. I am now working in a program to plot high resolution maps. Moreover, I am considering in the near future a project of developing a new printed atlas, more powerful than the Millennium Atlas.
Do you want this atlas for you?
I have prepared a PDF document with the first maps. It is free, follow this link. These considerations led me to the idea of seeking something similar to a giant binocular, but with larger magnification. Could a large spotting scope be useful in deep sky?
Finally, I found something that fits in this idea. It is a large spotting scope, which combines a 2. Both objectives can be interchanged by flipping a mirror.
The light path is folded, so the instrument is surprisingly compact and light. In order to make this telescope more functional, I coupled a 9x50 finder and a Manfrotto three-axis system on the geared head to make starhopping faster though keeping accuracy. The picture on the left shows the appearance of all the components assembled. Zooming the image reveals a lot of detail, and objects that are totally faded at less magnification become visible.
Key feature number 1: All of them are good. That said, which one is best for you? That depends on your experience, your goals, and your telescope. Such atlases show stars to about magnitude 6. Beginner atlases also show a wide swath of sky on each page and may include constellation outlines. These atlases also limit the number of plotted deep-sky objects to only those visible through a 4-inch telescope. That list includes the Messier objects, selected objects from the New General Catalogue NGC , and the brightest and most colorful double and variable stars.
Sky Calendar from Abrams Planetarium part of Michigan State University has been helping beginning observers learn the sky for more than four decades. Abrams Planetarium Introductory atlases My first pick is not a traditional star atlas. Still, for four decades, the Abrams Planetarium Sky Calendar has promoted basic skywatching.
As its name implies, the sheet for each month takes the form of a calendar. The Sky Calendar is a great quick reference for beginners and advanced amateur astronomers alike.
And while most of the star atlases in this story contain thousands of stars, the Sky Calendar shows only the brightest or so, depending on the month.
That number works well for beginners or for those who observe under moderate light pollution. Abrams Planetarium publishes the Sky Calendar in loose-leaf form and mails it quarterly 3 months per mailing. It also includes approximately 1, double and variable stars and deep-sky objects. This page work contains 12 charts, each with an index of objects.
Overall, the atlas contains roughly 7, stars to magnitude 6. The atlas also plots nearly 1, double stars, variable stars, and deep-sky objects.
Crowded regions in Orion, Virgo, and Sagittarius have detailed close-up charts that make it easier to tell one object from another. The first edition dates to , and in , Benjamin Cummings Publishing released the 20th edition. Six rectangular charts divide the sky into segments 4 hours of right ascension wide.
