yes they are great for grab and go, if the weather is iffy then its my scope of choice as its easy to set up, if it rains, can just be picked up and thrown on the back seat of the car, and is tough enough you could literally throw it into the car. its also a good scope to demonstrate the workings of a telescope to youngsters (and also a good height for them to use - and tough enough to stand them using)

Well... for anyone still watching this post...

 

Стив, спасибо за то продал мне этот телескоп, и это будет весело встреча с вами позже сегодня!

So have you used it yet? If so, what do you think? That has to be one of the tiniest Newtonians around!

Glad you asked!!!! 

 

Well, I didn't even open the box on the first night... and after spending all the next day moving furniture (and in that there were very few patches of clear sky that night), I decided to open the box as there was a bit of clear sky allowing Venus to poke thru...

 

So after getting up off of the ground from rolling around laughing at this goofy piece of gear, and then my having to field comments from friends on how I now have something in common with our President Trump... a comment about me "Putin" it together... and a few comments on it being made from salvaged gas pipe from Chernobyl... I was absolutely dumbfounded on the view!

 

Keeping in mind that we had poor skies anyway, I couldn't believe how crisp the view was... at the 33X that the 15mm eyepiece offered, the crescent was as crisp as I'd ever seen it, and the rest of the sphere was dark with a beautiful fairly bright outline... I had the Barlow it came with handy and put that in place... 88X ... the view was just about as good... a bit less crisp, but hey, whatcha want for stove pipe, right?

 

Overall... probably the best $$$ I've laid down on a whim...

 

Its pretty awkward to be leaning over all of the time for extended periods of viewing... and the 2 little pieces of strap metal with holes in them used for the 'finder' system has a lot to be desired, but this is a fun conversation piece that is quick and easy to assemble, light enough to carry around, and because of the respectable view, will probably get a bit of use for those spur of the moment clear sky fixes...

 

Thanx!

:band:

Novelty??   :shrug:     (The Alkor is a serious astronomical instrument designed for very short people. )

 

A previous owner had done a clean job of drilling and tapping the OTA for a telrad. It took me awhile to figure out why the two holes were there -- then it dawned on me.  He also drilled/tapped a pattern of tiny holes on the OTA -- it’s more precise work than I could do.  I believe this was with the intention of repositioning the OTA against the saddle so the focuser will be closer to vertical.  I haven’t tried that but I will.  Viewing will be lot more comfortable if I can put the focuser at a different angle.  Enjoy your Alkor.

Cool... makes sense... It is fun... I can also use it as a paper weight for my astronomy papers...  is yours pretty crisp viewing too?

Low powers looked good but not the high range.  The centering and tilt of the secondary were off when received. Tweaking the bent-metal stalk needs more concentration and time than I’ve been able to give it.  On the to-do list.  I also want to check the secondary against a flat -- the secondary mirror on my TAL 1 was mediocre. But the Alkor is a neat package, worth some effort to unleash its full 64mm potential.

Hi,

I got the same telescope around 2000, from a flea market seller.

My scope still offers amazing crisp views in all magnification range. I agree that is collimation is quite tricky, but it is well spent time.

See it behing my 154mm apo refractor.

 

Regards
