    Default First impressions of Interstellarum Deep Sky Guide, a short review.



    Interstellarum Deep sky Guide.
    After waiting a long period of more than six months, it finally arrived. My copy of the IDSG. I had ordered the desk edition. English version. I never take an atlas or a guide out in the field any more, since I make my wish-list at home, accompanied by an atlas ( IDSA), a guide and a cup of coffee. Out in the field my cellphone-app SSPro is my buddy. Until two years ago I took my atlas with me in the field, nowadays I consider a nice atlas and a good guide as the perfect buddies in the warmth of my living-room. Anticipation is part of the hobby.

    The first real atlas I ever bought was Norton's. The Interstellarum Deep Sky Atlas ( German version) was the most recent one. One of the best too. The last Guide I bought was the Stropek Deepsky Beobachteratlas. But when I heard about the IDSG, I knew I had to have that one too, since it forms a perfect couple with the IDSA.

    Dimensions.
    The dimensions are all right, the ring-binder allows it to make it an 11X11 inch format, so it still can be put on any observers's chair /table. The waterproof Field-edition will feel better at home there.

    Introduction.
    The two introduction pages give account of the chosen methods and choices, and contain a brief manual.

    Ranking and finding objects.
    Like in the IDSA the objects are chosen according to their visibility ( experienced observer) and useable telescope size (4, 8, 12 Inch and Challenge for bigger) under moderately dark skies. Bortle 4-3. This is a pleasant and accessible way of ranking, since one doesn't have to wonder and calculate if the object will be visible.

    Each set of pages has a numbered list of objects ranked by telescope-aperture and an inset, mostly on the right side. The list contains the objects and a very short description of it. The inset shows the position of the objects in the ISDA on the matching pages. The IDSG pages are oriented the same way as the IDSA. This makes it very easy to compare the Atlas with the Guide. If you just superimpose them, you'll have an overview at one glance. Quite a relief as most guides give you a hard time on finding your object in the atlas and vice versa. This new approach looks a bit like the Stropek, but is more clear.

    Each page contains pictures and sketches.

    Images.
    The 1729 images are the main feature. They are composed by combining blue and red plates from several surveys. This was done on purpose, since shining on them in the dark with a dimmed red light, makes the red image dissapear, and the blue image come forward. Like observing with our dark adapted human eye on 510 nanometers. In daylight the effect can be reproduced with a red coloring filter. In the Guide- images stars are encircled that you can find in the Atlas. Makes it easier to orientate and starhop / search. Every photograph has a small blue scale bar in the right corner of one arc minute across. I find that feature very helpful in estimating the size of what you are going to observe.

    Sketches.
    The 821 sketches are all in black on white and drawn by the two writers / observers Ronald Stoyan and Uwe Glahn themselves. These are certainly not "at first glance" sketches, but made by experiences observers and sketchers doing their utmost to retract details from the fuzzies they saw. Each sketch has the initials of the maker, the size of the instrument, the magnification and any filter used. Some sketches like those of M57 and NGC6888 go as deep as magnitude 15.5 or deeper with instruments of 14, 27 and even 48 inch!

    Accessibility.
    Accessibility is made easier with the list of catalog abbreviations on page 0, the index of nicknames and the index of DSO's by catalog numbers on the last pages. The very last page has a list of the constellations and a small list of errata in the IDSA.

    Points of criticism?
    The ranking for visibility is done according to the aperture under Bortle 3-4 skies. That is a choice. For Urban or suburban observers the visibility of some of the objects may be a bit to optimistic. As an observer you have to take that in account.
    The list of objects given at the right upper corner of the pages could perhaps give a bit more information like apparent magnitude. A bit of peanuts perhaps.....


    Conclusion.
    It is amazing how nice the Guide matches the Atlas. Never seen this before. This is an outstanding piece of work, suited for any advanced and experienced visual observer. Photographers will find more than enough inspiration for new objects. And even the most stubborn hard-core faint-fuzzy-hunters will leave their Uranometria Atlas and Guide more often in the library and use them just as a reference-book. Instead they too will more and more look for new objects in the IDSA and Guide. For me it was love at first sight....

    An observers' relief.
    As some of you know I do some sketching from time to time. Last holiday I sketched NGC 6888, the Crescent under a Bortle 4 sky through a 5.5 inch Maksutov. When I received the Guide I wondered how Ronald Stoyan and Uwe Glahn had done that. As a matter of fact the sweat was on the forehead when I openend page 17b, where NGC 6888 was to be found. Ronald Stoyan had seen more details with his 14 inch telescope, as to be expected. But the overall view was about the same. Pffff...quite a relief!

    Thanks for reading.

    Hello John,

    what an excellent review of yours!

    Ronald Stoyan and Uwe Glahn count to the 3 most experienced living visual observers of the deep sky objects,
    the third one to complete the trio, is Reiner Vogel with his exotic deep sky objects - not for the AP only.

    It has been Ronald Stoyan, who drew my attention to the Sh2-132 Wolf-Rayet nebula with his sketch through a 16" Dob.
    Not much later since his sketch has been published in the Interstellarum Magazine,
    I have nailed down this nebula through the binoculars with the Baader OIII filters,
    and since that time, I love to view this nebula, I nicknamed as the 'Stoyan's Challenge'.

    Thank you very much,

    JG

    The Galactic nebula "Stoyan's Challenge" in Cepheus is photographed in the IDSG on page 8b under #21. Not the famous sketch of R. Stoyan unfortunately. I can imagine this a very difficult one, a real visual challenge. It is categorized under "8 inch telescope"objects, with low power and OIII filter under Bortle 4-3 skies.
    And you did this with (giant?) binoculars and OIII fiter. Very well done! Chapeau!!

    Hello John,

    I can't find the sketch of Ronald Stoyan, but so fa I can remember what he has published, it has been a brighter arc over a faint fuzzy cloud.

    I have seen this nebula best through the 15x85 binoculars with the Baader visual OIII (10nm bandwidth) filters,
    which are better suited for the tough challenges than the Lumicon filters.
    The trick to see the Sh2-132 is to dim as much as possible the bright stars of the Cepheus OB1 Association across the nebula, otherwise the stars interfere too much. And of course, to keep the magnification low and the exit pupil high.
    This nebula is also known as the Roger Blake's X79 Challenge. I have seen it in total 35 times over the years.

    Chapeau à vous for your sketch of the Crescent Nebula,

    JG
