    Default First light Swarovski 10X30 CL



    Monday morning.
    Feb. 12 2018, 0141hr.
    Sky cleared and trans dramaticly increased from just 3 hours earlier.
    Swarovski 10X30 binoculars 5.7* fov

    I have been checking from time to time this evening. Bonnie told me the sky was supposed to clear after 2200hr. It did clear to brilliancy especially directly overhead but in general all-around to my N,S,E, and W to the Horizon.

    I sat on my deck with the 10x30 Swaro and my 8x43 Pen binos. The Swaros revealed to me a remarkable increase in contrast over the Pentax binoculars. Sky background was remarkably darker with Stars remarkably brighter revealing colors through the Swaros that would not reveal in the Pentax binoculars.

    I dressed up in my newly-acquired Carhartt bibs which I have purchased for the Messier Marathon along with a new pair of thinsulate lined boots and my down coat.

    I laid out along the side of the road in the open and scanned the sky. Ursa Major was almost directly overhead with the bucket of the Big Dipper nearly on top of me but slightly to the north edge of zenith. I had already looked at Star Charts and my messier finder charts and picked out two target objects that should have been in this area.

    After scanning Merak, Dudhe, Megrez, and Phekda and allowing my eyes to adjust and the binoculars to cool completely I first identified star number 68 on the IDSA chart just inside the bucket East of Megrez. I believe this is a mag 7 star. It appeared to have a bluish tinge to it. I continued to look at the many stars and spots of light in the midst of the bucket. Eventually I found myself back at Merak where I was able to identify M97 and M108.

    M97
    The Owl Nebula in Ursa Major.
    RA 11h 14m 47s
    Dec 55* 01' 09"

    M97 is but a Starlike object in these small binos. It is listed as a mag 9.9 which is consistent with a comparison in my view of UM68 which I had identified earlier east of Megrez.
    In the binoculars M97 is in no way a remarkable object. As I said, it is star like, slightly out-of-focus but not greatly so. It appeared as a fairly fine point of light. It was not the hot white of the other stars in the sky, but rather a dull point of light. I have identified it by its position in the field of view in these particular binoculars relative to Merak compared to framing view in DSO browser.

    M108
    A Barred Spiral Constellation in Ursa Major.
    RA 11h 11m 29s
    Dec 55* 40' 22"

    M108 is listed as a magnitude 10.7, and is an isolated member of the Ursa Major cluster of galaxies in the Virgo Supercluster. This object was more difficult to resolve I believe because it was closer to the bright star Merak. It lies nearly between M97 and Merak, a bit closer to M97, but almost in the middle. I was able to resolve it with averted vision after long viewing. I knew where it was supposed to be and its appearance was somewhat transient in flashes. But there were times when it was sustained for a few seconds. It appeared to display some color but this may have been a phenomenon of the rods and cones in my eye. It revealed no shape. It is definitely identified regardless of the color phenomena in the same way I identified M97. It is not Starlike. It is much more fuzzy and it appears to be smaller than M97, I suppose because it is not as bright.
    M108 is listed as being 32 million light years distant.

    I was very pleased that these little binoculars performed so well. I am very happy with them. Even though they have less objective than the Pentax, they outperformed them significantly.

    Well that was my first light with the Swarovski binos.
    Peace to you all.
    And may you all have good skies.

    Very good first light Mark, you have got excellent binos and you have excellent eyes!

    I also love my Swarovski EL Swarovision 8.5x42, it beats all 10x50 I have had. It is the contrast and brightness of the Swaro technologies which makes the difference.

    Looking forward to more from you,

    This was a surprising session for me JG. I was surprised that I was able to see with these small binoculars what I reported here, almost to the point of incredulity.
    If I happen to have the kind of sky tonight that I had last night I intend to take out the 25 by 100 oberwerks. I am quite sure, if the sky cooperates, that they will also deliver these two Targets. But I am Keen to compare the little swarovski with the much larger Oberwerks. I have given these Swarovski a name. They are called "My Nightingales" for they sang to me last night. :-)
    Thank you for your encouragements.

    Excellent that you were able to see M97 and M108 in the 10x30s' Mark. I've tried a few times with 10x50's with no success from home, however I can usually make them out in the 15x70's.

    From where I live M97 and M108 are a no go in most binoculars, even 20X80's are quite a challenge. So your location must be pitch-dark, I suppose? Well done!! It must be very satisfying knowing that you can master the universe with such a relative small instrument. Chapeau! Hope to see more reports!
    My Swarowski 7X42 Habicht is well known amongst the observers of Rijswijk public observatory. Not especially for its power but for its tiny stars and contrast. The optics are superb, and one notices it. They sure know how to make binoculars there in Austria!

    Thank you John. My skies were the blackest I have seen all year. This deep clear came directly behind a heavy cover that rolled off about 3 hours before I made my obs. The targets were also directly overhead, so least atmosphere. The targets would not have been recognized but for the fact I knew where they were supposed to be and had studied this particular area for them.
    Both of these targets were the tiniest dimmest items in the field so it was not a spectacular view by any means. But these swarovski's showed me very black sky and penetrating brightness of stars. The sky condition, the position of the targets overhead, the Optics, and my keen awareness of where these should be and the star fields around them and their relationship to Merak are all contributing factors to this successful observation for me.

    Thank you John.

    Yes, you are right, I forgot to mention it: the black sky in a Swarowski. (Almost the ) same as highcontrast by daylight.

    Hello John,

    at the small apertures, I am using the Leica Ultravid 7x42, Leica Ultravid 8x42 HD, and Swarovski EL Swarovision 8.5x42.
    They all reveal the Le Gentil 3 "Northen Ink Spot" in Cygnus, Le Gentil 3 – Catching the Light , even under my backyard skies.
    The dark nebulae are often better test objects for the contrast performance of the optics than the bright nebulae.

    Best,

    JG

    Great session and report, Mark! Sounds like you have a keeper there for sure.

    Messier Marathon? That's a bunch of work. I've done one and swore I'd never do another.
