Quote:I would very much like to be able to read this book. I've been aware of it for decades...An interesting contrast would be afforded by a modern treatment, where filters and updated astrophysical knowledge could be brought to bear.I have a modern 2.3X40 opera glass (of the Galilean configuration) which would be a nice complement to Serviss's (and an update's) treatment.

I would also like to read this classic. I have 2.3x40 also and have used skyglow filters with sucess to see Lagoon, Orion, and even M27 dumbell as a blinking. I believe I also saw the faint north american nebula. Andromeda looks just like the sky charts. I also love the hands free headset I have for them and enjoy it with my zero gravity chair. Also best wide field view of Milky way, and Pleadies and Hyades in same FOV, etc.
Quote:Nice photos. I like the inclusion of those old opera glasses especially! Out if curiosity, what are their 'specs'?As to image size, go with a width of around 800 pixels, and a moderate or slightly high degree of JPEG compression (no more than 5/10 quality.) This will be friendly on those with sloooow connections, or limited data plans on their phones (like me.)

Quote:I was thinking about selling my copy but after reading this thread I think I'll keep it. I like the introduction of the book too. He talks about how most people don't know the main stars and were confused about what Venus was - and that was 1888 so things perhaps have not changed that much in that regard.Dave

Quote:bumm...Thank you for your review of Astronoomy with an opera-glass and the photos of the excellent items in your personal collection. I have thought many times of adding an opera glass to my current optics collection--but somehow they always seem to get edged out by other items in the budget. Maybe . . . someday . . . Thank you again for this thread.
Quote:OK, sounds great. Where and how do we get them?
Quote:Quote:OK, sounds great. Where and how do we get them? Search "Kasai 2.3x40" it will be in Japanese with images. Internet has a translator which is not that great, but Kasai does have an e-mail address which they will quickly respond in english. They will translate the yen price into current $US (or currency from your country) and after you pay by pay pal they will send it to you.P.S. You can read up on the russian and blue planet optics ones as well, but those are no longer made. I believe they probably sold the rights to Kasai. For eye glass wearers, please note these are near zero eye relief the closer to your eye the wider the view, so you need to observe w/o glasses!
