    These unistellar telescopes are indeed impressive. I see now that Pluto has been imaged via a 4.5" reflector!the original observation was made in Marseille France and later checked by another amateur astronomer in San Francisco, photographs where taken to prove both observations too.I previously mused what the result would be if the unistellar eye piece and software where fitted to my tiny 25mm/1" pocket Borg refractor.... I think pretty impressive?

    I would like to know how & why this 'unistellar' is named in full as: Unistellar eVscope? Here's why -

    Part of a thread here goes into some eyepieces that have hit the market and members here have been buying these eyepieces and writing reviews, etc. These EP's are from a Chinese outfit and listed as eVbony Aspheric eyepieces (and several other names & brands).

    https://www.amazon.com/SVBONY-Teles...&qid=1508632345&sr=1-4&refinements=p_4:SVBONY

    It is looking like the "Unistellar" eVscope & the sVbony eyepieces are related. These eyepieces are very good indeed. A set of three in 4mm, 10mm, & 23mm is selling for $35.99 through Amazon. Now for the obvious question/suspicion -

    Could this telescope be related to these eyepieces and really be coming out of the People's Republic of China? :eek: :confused:

    I doubt that the eye pieces coming out of the PRC are related to unistellar as unistellar is French. The Chinese eye pieces are probably just normal eye pieces with a similar trade name and if you put them in a telescope you'd get a normal result.visiting my sister who lives in a large city,sort of halfway to the edge,and the guest room has a south east facing window.so I did a bit of observing, only about 20 minutes, of m44 and m42 using my 25 mm Opticron monocular last night. I was left to think what if this small aperture could be fitted with a special light collecting eye piece.of course it wouldn't work on the monocular as it has a fixed eye piece being nitrogen purged but the 25mn pocket Borg could be. At the moment the unistellar eye piece and light enhancing section looks bigger than the pocket Borg!but as technology improves it'll be shrunk.

    I think if they could shrink this technology to the size of a bacteria or something I might be able to use my 4mm AH ortho in it.

    That's it! Nano-Tech. Telescopes! The size of a couple of atoms.....

    They could also be used to battle cancer and build nuclear-weapons!

    You do realize this is not a "telescope" per say but an imaging system that enhances the view over time?
    It can be used as a telescope if you shut off the imager but then it is just a regular 114mm reflector.
    They claim "equivalent" of a 1m aperture which is xxxx, it can still only have the resolution of a 114mm telescope....
    Unless our version of physics has suddenly failed.

    I realize this. But the hyped advertising on it seems to <koff> fail to clarify this. That's why I'm using the analogies about other similar items marketed of this genre. Amongst some other 'turns & twists' in it's presentation.

    The 'Revolution Imaging' packing for $299 seems rather similar - though lower-end.

    Revolution Imager R2 System $299.99.jpg

    But it doesn't have a telescope included.

    Now I understand!
    I have seen to many beginners lately ask questions about it as they seem to think that this is what they need to be using for AP.

    There was a beginner on another forum how had just bought a 8" SCT and mount and was wondering if he should sell it as this "obviously" was a much better system than what he had just spend so much money on!

    I'll be quite happy to explain what's really going on here to anyone I spot entertaining this delusion - complete with history lessons. The first of this genre were, and remain, the best: AstroVid StellaCam II and III. Monochrome and really packed a punch with the highest quality in the field. And these cost a whopping $750 around 2003. Granted - they didn't come with a 4& 1/4" scope. I'd plug it into my Meade 12" LX90 SCT and wind-up with the light-gathering pull of a 60" light-bucket. Yes - I have one.

    Interstellar is sounding like 'Underhanded' might be closer to the mark, from my perch at least...

    Caveat Emptor,

    Dave

    Just seen an advertisement for the unistellar telescope and it costs $999 the ad says that it is 100x more powerful than a regular telescope. That's, no doubt, with the imaging system on!I'm guessing that it isn't the light gathering which matters but what you do with it after you capture the light?

    I would guess that it's allowed to build-up on the pixels and after a certain period of time, it's captured through a frame-grabber and can then be stacked and refined in all the usual ways.

    In other words - it's another video-astro-photography rig. My assumption is that people will be able to run the view through this electronic-eyepiece gadget where it can be fed as live to a small screen to show to a number of people at once, or to yourself. The usual lagtime is 15 seconds exposure. But maybe this works a bit differently? They aren't being very forthcoming in providing any specifics which would set this thing apart in any sort of significant way.

    If my 'gut-feeling' proves to be correct - there's going to be a bunch of newcomers to astronomy in general - who will be very disappointed. And I read previous statements from these people behind this telling us the price will be $1,999. Then saying if you sign-on the project (read: Invest), the price is $1,299. And now it's at $999? AHEM!

    <squeak! squeak!> Hmmm.... I smell a Rat!

    Only time will tell. But if I wanted to gamble, I'd go to Las Vegas or Atlantic City. Not France or China.

    That's my 2¢

    Macau is the place the Chinese go to gamble,it's not very interesting for the non gambling person like me but good and frequent ferries from Hong Kong and China.France go to Monaco for upmarket gambling.beautiful botanical gardens in Monaco set on a cliff.

    Macau is also noted for cheap fireworks. As most good juvenile-delinquents can attest. A former Portuguese colony - not heard about Macau in years!

    But, then, I don't gamble. A 'gentleman's bet' now and again. But no one will bet me anymore. I've never lost one.

    Cowards! :D

    Macau is still going! I went on a ferry from Hong Kong about 5 years back. Loads of casinos, old town sort of OK. Guess rather,very!,light polluted but it was cloudy when I was there.they get gallons of rain in that area.
