~ Anyone used these, and what is your experience with them? Thank you. .

~ The second video looks much like man-made junk disintegrating. Keep your hard-hat on. .

~ 14 pages on this one eyepiece? Brother! .

~ Buy once, cry once. .

~ I would be grateful if Springer would publish a less costly paperback of Merlitz' work. .

~ Wrong forum? .

~ Hardly anything compared to the C-14 I used to heft up onto a G-11 every use. That one is gone about 20 years now, and my back is grateful. .

~ I like the 3.7 best. It's the only one I own. .

~ An Ultima by any other name.... Forgot about my wife's binocular kept in the toy-box trailer. I bought these in the mid/late 90s. .

~ Here are my only Ultima binocular. I don't remember when I bought them. Optically excellent, the glue securing the leatherette covering is beginning to fail. .

~ Um, let's just say it involves plumbing/apparatus function, and leave it at that. .

~ Can't help with dating this branding, but Celestron marketed a line, also called Ultima, which appear identical to your unit. They were discontinued some years back when virtually all production shifted to China. I seem to recall the Celestrons becoming scarce around 15 years ago. But, memory being the second thing disappearing with age, I could be mistaken. .

~ My adult pursuit of this hobby began just a quarter-century ago, so I haven't been collecting astro-books very long. The artwork of Chesley Bonestell prompted me to get a copy of "The Conquest Of Space" written by Willy Ley. My copy published by Readers Union with Sidgwick And Jackson, London, 1952. Edit: I just found on my bookshelf a 1935 2nd edition of "A Guide To The Constellations" by Barton and Barton, autographed by Samuel G. Barton 14 NOV 35, to Sarah Lippincott of Germantown, Pennsylvania, who purchased it a month earlier for $25. .

~ 03 APR 24 Pons-Brooks in Tasco No.216 10x50s. It was brighter tonight than my 21 MAR 24 sighting of it. M45 was perfectly framed with the Tasco bino. Also had a look at the comet through my Zanzutsu (Japan) 60mm f/13. M42/Trap also viewed. The Pup undetectable through it, however. .
