This scope was epic!  It was designed and built in the Halley era to show the the great comet.

The Halleyscope!

 

Lest you think it not up to the  task, witness this image of the moon!

 

Now, the image quality...leaves something to be desired, admittedly.  smile.gif

 

But stripped of its eyepiece which is needed for infinity camera focus (one reason I dislike digiscoping) it's not bad.   The lamp harp imaged at 20ft shows reasonable detail.

Meanwhile, the sheer insanity of digiscoping means the scope operates (at its top power) at an f-ratio of about 68 causing diffraction to OBLITERATE detail in the image. Now, if I only had a camera coupler that was about 1 inch shorter, it could work at prime-focus.

When i worked in the photo industry i was lucky enough to attend the photo marketing association (PMA) convention every year. It started in chicago but by the eighties it was in vegas every year around february. Either 86 or 87 when i attended i saw the halleyscope at their booth at the convention. To me it just looked like a rebranded and packaged spotting scope. They hyped it as the best way to view the comet and even though i expressed my doubts to their reps, i dont think they paid any attention, they probably sold thousands to camera stores. Edmund scientific was their also giving away free jumping discs which were cool and i do remember purchasing  a portable digital PH meter at the PMA that year (70-100 bucks) which i used in my work for a couple of years till it broke. 

It got me thinking that i dont remember ever seeing meade or celestron or any other big scope manufacturers at those shows. I wasnt into the hobby at that time in my life but i was as a kid and certainly would have stopped and looked if unitron for instance had a booth. I know camera stores carried telescopes in the 70's and 80's. those were big shows, i guess i could have missed them. So good for halley scope for sticking in my brain all these years, they are good memories.

Never buy anything optical with "Halley" imprinted on it.  ;)

Is it mounted wrong?

 

 . . . and the lamp photo does indeed show detail

Generally true, but I quite like my Televue 101 Renaissance Halley's Comet Edition.

Was the moon photo taken through a window while the lawn sprinklers were on, hitting the window?  belushi.gif

I have one of these Halleyscopes and I don't remember the images being so bad on the moon. I haven't used it in a while but I will take it out again when I get a chance. Last time I used it I was pretty impressed lol.

Hey KoKathaman, if I didn't know any better I would swear that is very, very similar to the scope that was shown in the first Indiana Jones movie in the scene where they go see the "old man" who tells them about the inscriptions on the "head-piece".  

 

"..they're digging in the wrong place......bad dates!..."

 

I Like the scope, is it refractor or gregorian?

 

Clear skies, yeah, don't I wish!

...you've had me go back through all those links to try & dig up anything about the scopes Halley used & this one that I posted in particular..no luck - but I wouldn't bet too much on Indie or his Dad having owned it - but you never know..! lol.gif

 

Halley probably used a few & his resume is pretty impressive btw: played a significant role encouraging, proof-reading & editing as well as funding Isaac Newton's Principia, among many other things including the designing of a diving bell that took him & others to the bottom of the Thames River 60 feet under...but if I was taking a punt I'd suggest it was a Gregorian as these were the most-used types at that time...

 

Glad you asked because although I had a fleeting awareness of Halley's significance, his achievements are far more comprehensive in many fields than I ever previously realised..! waytogo.gif

Sometimes optics don't play well with cameras that work ok for eyes.  Microscopes are worse than telescopes, on average.
