  1. Sorry for Language, I helped myself with a translator. 09/21/2019 I was getting ready all day for this night. A friend with 20 "Newton was supposed to come but eventually I was alone. Tea in a thermos, sandwiches and a table ready. A friend warns me of inhuman moisture, so I also brought electricity and a hair dryer. Despite forecasts it only cleared up after 9:30 PM, so until "moonrise" little time left. The equipment used for observation is GSO 10 ", UB filter, bino +1.6x GPC + Morpheus pair 17.5 mm (~ 115x, pupil 2.2 mm), Meade UWA 24 mm 82, ES 18 mm 82. Conditions: high humidity, Moon in the third quarter rising at 10:00 PM local time, medium transparency. I set the Double Cluster in Perseus as a warm-up. In the 18 mm ES eyepiece, a beautiful view, the entire frame filled with stars, both clusters are within the field of view and the cat's paw adds charm. I also tried using Morpheus 17.5 mm, also a great view, a bit more flattened field of view, smaller problems with sharpness at the edge. However, the best view was served by Meade, a wonderful large 1.6-degree field filled to the brim with diamonds. Very comfortable eyepiece, I'm impressed. Veil was next in line, as I never get bored with this object. In the Meade UWA, armed with a UB filter, it wonderfully pulls a feather and a broom from the background. The mass of frayed parts as well as the various elements of the Pickering triangle !!! I don't remember seeing them so clearly in SWAN 33, unless the exit pupil was too big in it. I stayed with it for a moment to remind myself that I haven't tested properly the bino with 1.6x GPC + Morpheus on DS objects. M13 in Hercules in Morpheus looked phenomenal, beautifully splitted up almost to the center, a huge supply of field around the cluster. I took off my eyecups and all I have left are the lenses, big and encouraging to look. After this Trick, looking at a bino looks like looking into a magic well Total lack of diaphragm, just ends the 76 degree field of view filled with stars and the real world begins. 110x power is the perfect fold for a 10 "mirror, the set works great. I looked at the neighboring NGC 6207, it appeared as a delicate mist, rather bino did not help her. M92 smashed into stardust, concentrated inside, peeking out gains a lot of brightness, the nucleus is very bright, the perfect object for two eyes. The Cat's Eye planetary nebula in Morpheus is wonderful, 110x times it was enough to see its slightly oblong shape with a very bright center, the color is a delicate blue. The time has come for something more difficult. NGC 6934 in Delphinus, I was planning to play with her a larger mirror but GSO also showed something. The cluster is strongly compact, slightly brighter center, very delicate graininess on the edges, hulled with effort. Viewed in a bino with 17.5 mm Baaders. The more difficult cousin NGC 7006 is nearby - there is clearly a lack of resolution here. The cluster is perfectly visible as a small blot, on the verge of recognition as a globular cluster and not a galaxy. I will come back here with bigger, better equipment and look inside this ball. M15 is very close so I aim at it and I see a very bright cluster with a particularly bright nucleus, it reminds me of the sharp, focused nucleus in M13. Definitely different from other bright globulars. It is the nucleus that catches the eye, the view is first-rate. Pacman Nebula - this is the first time I approach this object, it goes out easily in Meade 24 mm with a UB filter. The moon is already quite high in the sky but the nebula shows its beauty, but it's hard for me to see its mouth, it gets blurry in this place. I have everything wet, I go with the hair dryer to secondary mirror and the finder and dry every now and then. If it wasn't for the proximity of the house I would have to stop observing I move to the other side of the sky where the Moon does not yet dominate, I want to look in several places before it brightens the sky. First to my favorite Cluster M71. In 24 mm it pops up as a beautiful density of stars, not very bright as a whole, when I look at it I see practically two levels of brightness, one internal with an irregular shape brighter and a delicate halo around also with an uneven shape. A magnificent view with a beautiful star field. In the ES 18 mm, a similar view only slightly closer did not bring much new to observation. I look into the M57, tiny bagel always enjoys, I did not go into a lot of power because I wanted to go to next target. I wandered to M27. Without a filter, large and juicy dumbbells in ES 18 mm, the sky slowly shines so I put on the filter and watch again. This time the stars are dimmed and the nebula itself is beautifully exposed. Maybe it's an illusion but I see a delicate blue color similar to the Cat's Eye? Usually, as we watched her in 20" with filters, it fell into green ... probably something has come to my mind because the stars around were just turning greenish. I tried to fight the Sadr Nebulae, but it's probably not an object for the GSO 10 "or I don't know how to watch it, something like delirious. I aimed at North America with Meade and UB. Beautiful brightening with a regular shape. The bay and Mexico itself are clearly visible. Studying its structures, I came to NGC 6996, a delicate cluster of stars inside the nebula. Pelican Nebula visible but I did not look at it closely. Finally, I jumped into the Crescent Nebula - the moon was already high in the sky, it was 01:00 am, Meade and the UB filter showed me the nebula as a delicate glow in the shape of an incomplete arc, unfortunately, that's all I could see. It looked like a light streak, similar to Veil without filters. Around 1:00 am I went to sleep setting the alarm clock at 4:20. After a nap, I returned to the telescope. Of course, I thoroughly dried everything with a dryer because every element flowed down with water. Backpack with boxes from eyepieces all wet. Moon high, I don't remember watching it at such height for a long time. The third quarter is wonderful, everything around sleeps hard sleep, awakened and slightly shocked by the cold I looked at the moon, so cold and lonely. Orion is already high, so I don't think much, I packed ES 18 mm + UB 2 "and aimed at M42. The nebula jumped out of the background showing itself proudly, of course I could not count on beautifully spreading wings with the Moon over my head, but the view was still great. The central part is light enough that it rests easily I have seen a few dark trusses inside it + a trapezoid with 4 stars. You can feel the breeze of autumn and winter when you can already enjoy Orion. But I didn't get up for that, I was more interested in the Moon. I was counting on a beautiful spectacle with his participation as the third quarter is less known and less frequently watched. I put a bino with Morpheus and 1.6x GPC, which gives about 110x and a 2.2mm exit pupil. The entire moon with field reserves is within the field of view. You can see the delicate waving of the air, the atmospheric front goes, but the picture is sharp and full of details. After a while, I was not enough, I change the equalizer for Barlow GSO 2 "ED screwed into the reduction. Power increases to about 180x. I tirelessly comb the entire terminator line every now and then returning to the stars of the evening - Copernicus and Plato. I almost forgot i have a Pentax XF 12 mm pair. I went quickly for them and after changing to Pentax the magnification increases to around 250x-260x. Now it's fun. Magnificent view. The atmosphere is trying to ruin it for me, but the height of the Moon does its job and the details, despite the fact that they are gently waving, remain fully visible all the time, occasionally sharpening so that I am not sure if I am still standing on Earth or already in the Moon Probe cabin. Copernicus shows a great interior, slopes covered with terraces, inside several peaks and various creations. Mass of small craters around. Apennines cut strongly beyond the edge of the terminator. I'm going lower and focusing on Plato. Inside this crater there is a lot of small craters used to check the resolution of telescopes. I decided to take a closer look at them. I can see only two pieces but they appear as craters with a dark and light part. These are not bright points of light that I saw in TS 102 F11 AC. Plato himself is filled with black claws of shadows, probably one of the claws hid from me a double mini crater inside, I am sure I would have seen it if it had not been for the shadow. After successful play, I finish today and take my eyepieces home, it is already dawn. I have not mentioned yet the travels in Cassiopeia with 24 mm UWA. Too many stellar objects and I wasn't able to find myself there but what I looked at is mine I think I remember the star asterism "S" the most nice 09/22/2019 It was a night I haven't experienced much in my life. The transparency was amazing. Unfortunately, that evening I could not use the telescope but I could not afford to waste such a night so I took old Nikon VII 10x50 with me, a dog and went into the field to cover the lighthouse and LP from the south with a small birch forest 100 m from the house. What a night it was. It's hard for me to catalog what I saw in the "shield constelation" but wherever I looked it was either a nebula or a cluster, a truly magnificent view. The Lagoon nebula itself was pushing itself into my field of view, it was impossible to detach itself from it, stretched between a row of bright stars. The Trifid Nebula was less visible but was there. Above them some star cluster, then another, probably M23. M22 shone beautifully, M25, M24. I looked towards M11 on the way past the next objects. It was a pity I finally had time to rummage in the SkySafariS to know what "number" I was looking at, and I was not sure of the markings anyway because that wasn't what I was interested in right now. I just stared and was shocked at the density of the object we just have under our noses and a few or several degrees of latitude are missing to be able to soak up these treasures. Overhead clear sky which I had little in my life. I aimed at Veil, after I realized what field I had in front of me and where to expect "feathers" I saw the fiber without any problem as a delicate outline. I'm shocked at how easily it came to me. Then a glance at M13, M92, my favorite M71, M27, M31. I also looked at North America and I could easily see the shape, mainly with the help of this dark pitting. Finally I put down my binoculars and looked with the naked eye. I am 90% sure that it will be distinguishable even with the naked eye, I could not locate the Gulf of Mexico only this dark gap between Pelican and NA but I but I didn't miss much ... I felt so. Now a bit extreme for me because I started after NGC 6934 in Dolphinus and won this battle delicate ball but definitely visible straight away, it did not make a big difference. I am impressed, the day before I tried to break it in a 10" mirror and today I look at her in 10x50 binoculars I glanced at the droppings at M15 and headed home, unable to believe today's conditions.
  2. I wish I had seen it before, I would have taken both for binoviewing maybe next Time
  3. Mods pls remove add. Thank You.
  4. Im looking for Sky Quality Meter. Regards Luke
  5. Hi, Let me add my observations from April 16, 2019. As I am a die-hard BV fan, I often compare mono views to bino views. Here are some of the observational notes and conclusions. TS Individual 102 F11, WO BV, SW 2" dielectric diagonal, pair of Pentax XF 12 mm and 8 mm BST ED. ...................................... 19.04.2019 Yesterday, the Moon was a great object for observation, good and stable conditions, sharp edges of craters. One of the coolest effects was to fill the Gassendi crater with light in just 2 hours !!! It was great, at the beginning only the peaks and a little interior were lit, and by 22:00 the light was streaming into the interior showing a beautiful relief cut by a network of cracks, craters and hills. I was delighted with this view. I spent a large part of my time on the Bay of Rainbows where the details of the "half-moon" were wonderfully drawn, I could not decide if I prefer this view in 140x or 90x Every time I changed my eyepieces I was overjoyed and I have no winner. In the south there are countless craters, a lot of different forms. I always try to imagine how they look "from above" and not at a sharp angle seen from Earth where most of them remind me of a potato As the conditions were favorable, I decided to play with Plato. I spent a lot of time staring at him and changing the configuration of the eyepieces. Let me share the conclusions: 1. Looking Mono, I could find three craters inside Plato faster and more confidently than I saw with bino. When using bino, I also saw them but as if they were 90% of the time seen in mono. Certainly the result was also due to the fact that the mono was a little brighter and flashed to me with a "more certain" light. 2. At 90x and 140x I saw the same surface details. Both in Pentax 12 XF and 8 mm BST, I caught 3 craters in Plato as well as mini structures that I aimed at in the Bay of Rainbows. Proposal? The resolution capability will not jump with a larger magnification although it was a little easier to separate two tight objects at 140x than at 90x. 3. Mono can be more effective but it is terribly tiring. While gouging a delicate detail, we focus on 100%, the eye begins to give in, it begins to water. Looking binoviewer we have increased comfort, of course we are also straining to see something on the limit of the equipment capability, but we do it naturally with a pair of eyes, so the effort is smaller, it may take longer. Hence the conclusion that mono observations will be more effective but only in the hands (eyes) of an experienced observer. It should be easier for the beginner to extract the detail in bino because of the convenience and less eye strain, which distracts attention from the look of the detail. 4. I've remembered the most important conclusion 140x in mono looks like 90x in bino There is such a huge difference in receiving the view that you have the impression of a much larger magnification. Plato gave me three craters in my eyes, after returning home I checked on the photo which I put below, which it was and on which I will hunt next time. 1. Visible all the time straight ahead. 2. Visible 95% of the time, as it turned out in the picture there are two pieces for me as one. 3. I had to look at it often, sometimes it disappeared in the waving of the atmosphere. It was a bit more common in mono. 4. I did not know about this rascal, glued to the edge and it seems to be within my range, I will hunt him next time. 5. At this point, it always seemed to me that I saw something. Probably this illusion because the picture looks like it was a brighter area. There are some craters next to each other, which could merge into one but ... well beyond the reach of this lens. What do you think about it? 6. Is this one still within 102 mm of the lens under ideal conditions? I wonder if if I know his place, if he can be seen, he is not much smaller than number 3. I consider all observations to be very successful, I learned a lot thanks to them. greetings Luke ....................................... This is one of many observations comparing bino to mono in detecting small details. I did comparisons on various telescopes and various BV, starting from 100 mm achro or MCT 127 to Newtonian 20". The resolution depends on the size of the telescope, the bino will not improve the view but thanks to the comfort you can focus more and use the time to see small details. I'm not an expert but strongly recommend to everyone try BV P.S. I forgot to mention, scope is shortened to reach focus with bino without GPC so there was no difference in magnification on both mono and binoviewing. I apologize for language mistakes
  6. That looks awesome Mariosi, magnificent sketch.
  7. Hi, May I ask You for upload more pictures of the items? Luke.
  8. Prism... so there is a problem with Vixen NPL with mirror diagonal 1,25" it would focus without any doubts. I heard rumors that prism better co-op with achromats "reducing" AC. It would be Great to check that out under dark skies. I have a plan to compare that scope with Old Gold series ED 100/900 side by side on planetary and lunar work. On M42 there was no differences between them. Sharp trapezium, superb contrast on both scopes. Double clusters in Perseus, magnigicent view. Ofcourse less detailed than from 12" Newtonian but it was pleasure. On Moon with pair of TV zoom 8-24 set on 8 mmn there was no even hint of CA. Great colours, medium shaprness but propably because Moon was low on sky, maybe 1.5h after rising. Important thing, with 20 WO erfles added to Binoviewer set there was easily visible CA, yellowish little glare!!! Thats why erfles Goes away and i'm waiting for package from FLO with BST ED's pairs. Best view of Moon i have with 25 mm e-lux Plossl, superb sharp and no CA. I would be able to make more reports when sky will be clear. Sorry for english. Regards Luke
  9. Nice report, may I ask You a question?. This Takahashi diagonal is prism or mirror? Mine 102/1100 is TS brand. Using bino Wo and pair of WO 20 mm 66 eyepieces (~55x) I couldn't split Double Double. Adding Wo 1.6x barlow at ~90x magnification one of pair splitted with dark tiny lane. Second pair won't co-op with me this night and that time i didn't have any more pairs of eyepieces to check how it perform. If it's not a problem, maybe I'll hook up to your topic about this telescope? When I was looking for information about that scope, there were not so many of them, maybe in this way we will help others in choosing their first refractor
  10. Hi, 46P last time I saw 5 or 6 December. I waited in the dark of the bedroom for an adaptation to the dark. After 11 PM street lamps in the village went out and then I went to the balcony door. The comet jumped out of the sky background immediately as an airy, gray, sizable spot. She reminded me of the M33 in small binoculars but larger and more roundshape (Edit: I mean it feels like it was huge on sky using averted vision, not literaly bigger than m33 in binoculars, it was easily like half of the Moon) . Even then, if I remember correctly, it was about 4.1 magnitude? To be sure, I confirmed observations with the old Bresser 10x50 binoculars. In the binoculars were propably the size of the Moon with a brighter center. Beautiful view, I'm glad that I could admire it a few times this year but it was the first time with naked eyes. After 10 minutes, clouds have come and it continues to this day Regards Luke
  11. Thanks for reduced price. I've just order pair of 8 mm, 12 mm and 18 mm BST for binoviewing so... next cloudy month belongs to me
  12. Hey, Maybe it is not significant but I had the opportunity to compare 9 mm 100 degrees Lunt XWA and Omegon Panorama 9 mm 100 degrees in the daylight with F10 achro. I can only say that the above entries coincide with my observations. It was very hard to cover the whole field of view (almost impossible for me, im not using correction glasses) , when I pressed my eye to the eyepiece and saw the whole field then I fought with the blackouts, when I moved my eye away from the eyepiece, blackouts disappeared but the field of view was very limited, say to about 80 degrees. Fieldstop was terribly blurred, I can compare it with vignetting in binoviewers with long FL eyepieces. Maybe it would not be so significant for me if it was not next to Lunt 9 mm. XWA allows you to cover the entire field of view without any problem, there are no blackouts and the fieldstop is black and obvious like the night. Looking through Lunt is a pleasure while Omegon can cause some problems. Shame that i have no opportunity to do some night test for correction in Panorama. Regards Luke
