A Kickstarter campaign with a Nov. '18 due date, it's a 450mm f4 smart scope sporting a Sony sensor (IMX244) and a $2000 price tag as near as I can tell. Thoughts from our astrophotogs? Any equivalent's already out there (as far as the tech goes) and how do they compare?

It seems a very nice piece of kit .
You should be able to see far more than you can using youe eye alone , outside of the visible spectrum .
I couldn't see what the resolution is though for imaging .

It's very much outside my budget though , I am intending to convert one of my spare Sony NEX 3's to do the job better than a regular camera with a Baader DRSL Astro coversion filter It'll just need cutting down to size .

It looks very interesting. F4 is wide. 450mm is a little short but I think they are using digital zoom.

For visual astronomy it could be great fun (and looks quite portable compared to my 750mm/F4 (6" mirror) scope. However, I think you are looking at an EVF vs OVF style debate. Undoutably,this scope will show fainter objects whereas a conventional scope can be frankly disappointing unless viewing the brightest Deep Space Objects.   That said, there is something rather special about seeing the acual photons emitted all those millions of years ago and catching a faint glimpse of something is a great feeling.

For astro photos, my immediate concern is the mount - it's an ALT/AZ mount instead of equatorial. With any long exposures, it's going to have all kinds of problems.   Also, the 'spider' across the front entrance of the scope has three vanes. That would give three spike stars which might be cosmetically unappealing.

The sensor is 1305x977. If you digital zoom these it could be a bit of a mess if you view it on a computer screen. Probably very nice in mini-form in an eyepiece at the scope though.

It also looks like you are stuck with their sensor and can't change it or add filters.   You could probably spend similar money on a budget 'conventional' rig and get a bit more flexibility.

For a flashy grab-n-go astro-party set up, it looks like a good idea though.

    I think your right about EVF v OVF , swings and roundabouts .
    I remember when I got my first proper telescope , a 750mm f/5 .
    After looking at several targets in the sky I turned it to Jupiter .
    Straight away four of the moons popped into clear view and I could see detail on the planets surface .
    That was quite a WOW moment !
    I next turned it to Saturn and could also see the rings clearly .

    I'm not sure it would have been the same looking through an EVF .

    On the other hand , if your looking up through a light polluted sky with that scope , how nice would it be to see things that many people would never be able to see otherwise ?
    Thinking city dwellers here .

    It would also be a great teaching aid to kids , it'll get their attention easier than having to describe what's really there .

    The camera resolutions very low for single shots , but stacking should give you enough for a nice print .
