    Default Oberwerk 25x100 first light



    members/eagleheaf-albums-misc-astronomy-stuff-picture161282-m-11-star-sketch.jpg

    August 11 - 12, 2017


    Oakwood Illinois
    Dark Site on my road.
    9:30 - 12:15
    Naked Eye
    25X100 Oberwerk Binoculars
    Pentax 8X43 DCF SP Binoculars


    Sky Clear
    Seeing Good
    No Moon at beginning of session
    Moon rise to 15 degrees at end of session at 12:15 am.




    The Perseid meteor shower was part of my evening but I have recounted this experience on another thread.


    I set up the Obies on the Oberwerk Tall wood mount with a 5000 head at 9:30.


    NOTE:
    Last weekend when first I deployed this mount the legs were a bit tight and ‘sticky’ in the extending process.
    Consequently I have adjusted the Tall Wood mount by buffing the inner mating surfaces of the leg travel ways with Butcher Bowling Alley Wax.
    This has mitigated the sticky action and made it a real pleasure to deploy.



    After scanning with my Pentax 8X43s and testing the seeing and giving my eyes time to fully adjust I began to put my Obies through their first real workout.
    Facing Sagittarius and jumped from M7 to M6 to M17.
    I scanned Corona Australis.
    I popped up to the Small Sagittarius star field and generally just observed the seeing I was able to experience with this glass.



    In a word... it is Fantastic!


    Finally I decided to simply set the angle at roughly 35 - 45 degrees from the horizon and scan in the RA plane.
    In this process I found M11.



    M11
    As is usual I did not know this was M11 when I found it, but that is my learning style, discover, duplicate, navigate, differentiate. I then try to expand a general sense of the surrounding of my target object...identifying nearby star positions.
    In the case of M11 this process was quite delightful in that there were many nice stars and star arrangements which I could see and sketch.


    This fuzz ball presented at about 45 degrees from earth horizon.
    NOTE TO SELF:
    I need to have a more accurate way to determine this angle in the future.
    According to the IDSA charts this position is -6+ Dec.


    I should be able to figure this Dec number from my actual Long location and my angle of observation....I saw this somewhere but I forget how it is done.
    If anyone can tell me this again I would appreciate it as it is helpful in identifying where to look in the charts for my object identifications.



    This fuzz ball is accompanied close to the north and west by a pattern of stars that form a sideways triangle with its apex to the west by south being open to the east.
    The Eastern most star in the lower arm of this triangle closest to M11 is slightly reddish in color, and it is forward, to the East, of the leading star in the upper arm of the Eastwise open triangle.
    The apex of this triangle points southwest back to a dimmer two star set very close together which leads south by west again to another set of two stars of about the same mag as the first mentioned.
    This then leads more southward and drifting very slightly west to a string of 4 to 6 stars of higher mag plunging south which terminates by sharply curving in a fishhook shape back East and quickly north.
    The stars in the fishhook were much dimmer than those leading down to it...mag 9 I believe.
    This complete pattern is within the 2.4 FoV of my Obies.
    I have attached a sketch done at the binoculars of this star field.



    As I viewed this field it seemed to form a small scorpion shape to me.
    M11 is just East and slightly south of the open triangle that forms the front legs of this scorpion shape.



    M11 has a very sharp and bright focused star at its core with surrounding diffusion which later granulated and eventually revealed a very dense star cluster with averted vision.
    This increase in the view detail occurred later (10:25 pm) in the session as darkness increased and seeing improved before the moon rise.



    Below M11, to the south and East only minutes away, a double star is also revealed.
    It is somewhat entangled in the diffuse glow of M11 I believe, but it is to me a separate object as I saw it.



    This whole group is southwest of Altair approximately 20.3 degrees as calculated by using my Pentax 8X43 6.3 degree binoculars as measuring device.
    I was about three and one half FoV in this glass to travel from Altair to this M11 group.



    This area is also marked by what appears to be an irregular lagoon of darkness pushing into the edge of the Milky Way at this point.
    This group is inside this lagoon/harbor in the western edge of the Milky Way star matter.
    There is a gap here between two sections of the Milky Way that runs north and south and this is a very small indentation on the Eastern wall of this gap.



    360 DEGREE SCAN AT -6 DEGREES
    At this point I wanted to try simply scanning 360 degrees with my glass at the same dec as M11 just to see what popped up.
    Very quickly I came upon what I believe is NGC6366.
    This was very faint but detectable. It appears slightly higher in my FoV than M11. My Id came from IDSA charts.
    As I continued my scan East a big one popped. I believe M10.
    M10 is much easier to see. Quite a lot bigger and brighter than NGC6366, and slightly lower in the FoV.


    Saturn
    I was in the process of doing and dec scan from M10 to the south when I stumble on Saturn.
    Saturn was tiny but the planet focused well and there was not the chroma that I had seen last weekend when viewing Saturn under the bright high moon.
    The rings were well defined and the planet showed a dull low intensity brown orange color.
    This may be aberration...I am not sure....but it was all clearly focused with no fringe color.
    Saturn was an extra for the evening.
    At about this time my neighbors rolled up for a visit on my road. And my work for the evening was interrupted.



    THE NEIGHBORS
    Nice folks that live in the cabin next to mine in the Oak Woods. They had seen me when they came in earlier and asked if I was going to observe the Meteor shower.
    I told them Absolutely! and invited them to come back out if they felt like it....so they did.



    Between the sightseeing tour I gave them and general chit chat we spent the rest of the time...until 12:15 or so looking for Meteors and we had some nice ones for our entertainment. See my the post regarding The Perseid’s... elsewhere.

    PROFESSOR

    But before we saw any more meteors I took time to play “Professor”.
    It was really fun and I surprised myself with the things I was able to teach them....thank you all for teaching me....we then took a quick tour of M6, M7, The Lagoon, Saturn, M31, NGC869 and 884.
    During this time the moon had finally topped the tree line to our East. They enjoyed the moon until they could take no more and we then settled on a blanket with a beer to watch the meteors.



    THE OBERWERK 25X100 BINOCULARS
    This glass is truly remarkable.
    There is a dramatic increase in seeing with two eyes and two 100mm telescopes, which is in affect what I have here.
    They are like having an intermediate aperture telescope, between my 127 and my 80, but in reality they are quite more than that.



    I have yet to use any filters on Nebula but I will in the future.


    All in all this was a delightful outing despite my sore neck.
    I had taken a pain pill before I went out and it helped a lot…and the beer didn't hurt anything either.
    This morning as I write this I am feeling quite well and my neck is actually limbered up quite a bit, having been healed by the STARS and your good wishes and prayers!
    Thank you All.



    I wish all of you Peace.
    I hope you get a good look at the Perseid. Hopefully you won’t need a shower cap... :-)

    Hi Mark. That's a pretty good freehand drawing of M11 and the surrounding area. I am glad that you were able to get out with all of the troubles that you have had lately. This was an excellent report, and it looks like the Oberwerk 25x100 binoculars really came through for you. Thanks for your well written and fun read report Mark, and the kindest of regards.

    Thank you Michael.
    I was trying to make this easy to read with that font.
    My older eyes sometimes get lost in the smaller fonts.
    I am glad it seemed good to you.

    And yes….these Obies are really the stuff! I am sooo pleased that I did this.

    [QUOTE=Ozman13;1058521522]Nice report!!Honest to goodness Oz, these things are crazy!They really are two 100mm telescopes. The only difference is you can't change the magnification. But heck I'll just post one of my telescopes up there when I want a little magnification on go over to that. Or maybe I really don't need much magnification. :-)I guess it depends on what I'm trying to look at and how deep I want to dig. I feel like I have a really good set of equipments now with the 80mm the 127 mm and now these 100mm binoculars. I think the only thing I can imagine I'd want now would maybe be an 18 inch Dob...maybe next year. But really, these are the nuts! You are sooo right...but of course. :-)

    Hello Mark,

    I am happy that you are happy, as I have somehow supported your decission making towards theses 25x100 binoculars!

    Thank you for the first light, it's a great report!

    Clear skies to you,

    Thanks for the great report and sketch. Isn't it terrific when a new toy proves to all that you had hoped it would be? I just got a pair of 80mm Bushnells and I'm already musing about the next step in aperture. I'm glad that you seem to be recovering well. Keep healing and clear skies.

    I will definitely investigate M11 area more JG. It is a very interesting and beautiful spot. And I will look to identify "Dark Trifid".
    Furthermore, I am quite happy with this decision and thankful for your input. I will be a lot older before I outgrow the capabilities of this very economical pair of 100mm telescopes. :-)
    It is a great pleasure for me to learn JG and I hope it is as much a pleasure for you to know that you have multiplied yourself in a small way in the teaching. It is the family of the mind. There fathers...there are sons.
    Peace and Goodwill to you JG.
