~ Recently, I bought an Astro Tech 5.5 & 25mm flat field ep, part of a series with several f/l offered, the design of which is available under quite a variety of brand names. Impressed with their good eyerelief, flat field, light weight, soft rubber eyecup, small girth for the entire range, and low price, I decided to get the complete set - times two - for use in a binoviewer. Testing through a 120mm f/7.5 refractor Friday night proved my choice a good one. I have been using other ep pairs in the past, and will continue with them depending on the venue/scope, but if starting over, this set would be the one to get/recommend. They can be had in 25, 19, 15.5, 10.5 & 5.5mm flavors: .

~ From the backyard: Got lucky with the clouds: A crop of the above shot: Reemergence: Pentax K-3iii & D FA 150-450 .

~ Yikes! That would be catastrophic, here. 15-inches is normal for an entire year around these parts, with more than 90% falling from November through April. .

~ Well, better them, than us! .

~ Or, perhaps it won't find, at all! .

~ 122° wide rectilinear on full frame! .

~ Based on weather forecasts, I thought Tuesday night's observing would be my last for the next week, but by Wednesday afternoon it became apparent that this was not to be the case. Clouds were coming, no question, but I might get some eyepiece-time, beforehand. The GM-8/Berlebach was still outside so I mounted my Agema SD 120 near sundown and hoped for the best. Went outside 1830hrs to still-clear skies and immediately zeroed in on Saturn. The seeing was a solid good, with all-to-brief seconds of excellent. This allowed scaling up the magnification to 298x, and I simply adjusted my chair to allow me to park my eyeball at the eyepiece without effort, where I remained for some time, transfixed. This proved to be the best view during the current apparition. Titan and Rhea were the only moons seen. Noting the increasing clouds approaching, I moved on to Jupiter and watched as Io was occulted by the gas ball at 2000. No GRS available, alas. On to the 1st-quarter Moon, where I was able to ramp up to 418 horsepower at the eyepiece and love every minute. By 2030 the clouds began to enshroud our satellite, so I quit the field, satisfied. Stopped for a moment at 1930 to capture the rig with this 30-second exposure. A plane makes its way across the sky, entering from the upper left. .

~ Any observing is better than no observing - sometimes compromises must be made. So long as you're enjoying the experience, all is well. Please continue, and keep us posted. .

~ Had everything set up by 1800hrs, which is when the photos above were taken (floating ISO makes it appear much brighter than it really was) and I took a peek through the SCT at the Moon to check on conditions where they showed fair to good (but not excellent) seeing. Called my neighbor over to have a look and he was impressed with his first use of a bino-viewer. He does not own a telescope of any kind, but does enjoy an occasional look through mine. He went home, and I went inside for evening meal and to await darker skies. Returned to the SCT at 1915 and immediately went for Saturn only to discover the seeing had slid down to average/poor, evenly mixed. Titan and Rhea were easily held, Dione appeared on occasion, but no Tethys, and Enceladus was not seen, either. I can't remember the last time I saw Enceladus, probably because I've not trekked to a dark sky site for a number of years, now, or maybe it's just poor luck. I stayed at the eyepieces a full 20 minutes, but no improvement came forth. Moved on to Jupiter, as the GRS was crossing the meridian at 1940. I must say, my impression of last night's image made it appear to have shrunken tremendously of late, almost as if were an afterthought. I wonder if it will last through my lifetime, and I ain't young! I gave up on Jupiter, due to seeing, near 2000hrs. Moved over to the Moon, and perhaps because of the larger canvas and/or greater light throughput found the seeing was not such a hindrance, here. The day-short-of-first-quarter phase was pleasing to view; Aristoteles and Eudoxus both having portions of their floors still shadowed; rills and wrinkles winding across Lacus Somniorum and Mare Serenitatis; further sough along the terminator the oh-so-battered highlands. My neighbor returned near 2030, so we retraced my earlier steps, beginning with Saturn. By now, it was a complete mess, as if a jet engine were sending its exhaust across the scene. We quickly moved on to Jupiter, and found the seeing beginning to improve considerably in this portion of the sky. We did spend some time examining the cloud patterns displayed, and as the seeing continued to improve into the fair/good rating, more was revealed while the GRS moved closer to the limb. Next on to the Moon, as Mars was not yet at the altitude I wanted to begin with. My neighbor was floored with the lunar view, and spent considerable time exploring the scenery. Finally, it was time for the red planet. Ten days earlier my neighbor had come over to have his first look at Mars during the current apparition and it was not a terribly impressive one. This night was far different, with Syrtis Major prominent at about three-quarters of the way across the face, moving toward the limb, and the North Polar Hood becoming more prominent as the globe climbed higher. this was my most favorable view of Mars since the 2003 close approach, seen then through my C-14 which has been passed on to another owner. We swapped positions and compared our views for some time, on Mars. By now, it was 2300, and everything was soaked with dew, my neighbor had reached the limits of his clothing's insulation, and I was getting a bit tired, so I bid him adieu, and began carting everything except the SCT's mount back into the garage, finally retiring by midnight. Primary magnifications for this evening were 195x and 261x, with 335x proving too much. The Borg was never used this evening. .

~ Clear conditions with decent seeing predicted for tonight only, then cloudy for the next week. C-Nine-Two-Five w/ Denkmeier bino-viewer on GM-8/Berlebach combo (non-goto) for the Moon/planets Borg 90FL on Vixen Porta for quick panning around Waiting for darkness Report to follow... .

~ Ah, yes! I remember that one falling... .

~ Like you a 10x50 has always accompanied me while observing, but with diminishing star-counts due to light pollution finding one's way around can be difficult, at times. Kowa has a 6.5x32 also, sporting a 10° field of view which makes locating areas far easier than higher mags can. These are my first choice when observing from home, nowadays. .

~ Astronomics, which I believe is the largest astro retailer in the U.S. has their proprietary "Astro-Tech" line of products for us, and recently I learned of the PF flat-field eyepieces. Bought and tried one in 5.5mm length, which sports a 60° AFOV, 16mm eyerelief, and the flat field, all for $55! Othoscopics and original Ultimas, which I have, at this length are hardly usable, so this quite a nicety. If you have high-end oculars you don't need this, but it truly is an exceptional value. Other F/Ls available, some with 65° fields. .

Which ones? I have found eye relief with the 35mm too long, and with the 5mm too short. The 7.5 is OK for me, but a bit tight for bino-viewing. Orion Telescope, here in the USA, used to market a line called "Ultrascopic" which were very similar in design, but with greater eye relief in the 7.5, 5, and 3.8mm lengths, making them suitable for the bino-view option, for me. Good luck acquiring more. .

Just about everyone has one of these. I, too, had one at one time and foolishly sold it; now reacquired: Vernonscope, here in the USA, is distributing this model bino-viewer, which arrived Thursday just ahead of cloudy/wet weather, so I was able to test it under a clear sky. Excellent unit: Finally, these two publications arrived from Europe. Ordered 01 October, delivered today: https://discovering-astronomy.eu/index.html .

I discovered Leofoto products for myself about 18 months ago and find they are an excellent value. I have no proof but believe they manufacture tripods for several higher-priced brands. .

Sometimes you have to yell at somebody to get their attention. Guess they listened. .

Why I did not buy one of these when they could be had new is a mystery to me. I bought all the other Type 6 models new, and have been waiting (and missing a few classified ads) for someone to part with theirs for some time, now. Collection finally complete. .

Definitely helps. Try for Juno, as well. .

Pretty much. 4% Moon & Venus. .

I've been tracking Vesta each morning this week. 10x50s.

Curt, I looked at your page before going out this evening with binos and camera. Foothills west of me complicate windows of opportunity with regard to sky brightness, not to mention neighborhood trees, as seen from my driveway. I was able to obtain this image, about 33 1/2 hours after New. .

From the backyard, 5% Moon. .

1% illuminated waxing crescent Moon. Binoculars showed it, but, at no time could I see it in my camera's viewfinder, I simply guessed. Photo heavily cropped. Moon may not appear on some monitors. Aged: 25 1/2 hours. .
