It is, IMHO. The two tiny Allen screws that fix the flip mirror fix also the plug thread for the illumination unit.

 

Moving the mirror forward and backward loosens the plug thread and hence it is impossible to plug in the illumination unit properly.

 

Too bad. After I received the second non - working unit  I gave it up and switched to a Baader Sky Surver V which is less expensive and seems to be a more solid device.

 

Apropos illumination unit: This thing is the worst design i‘ve seen for years.

It disassembled by regular use around midnight last week. No fun to pick up the pieces.

 

The only thing I worry with is how to mount the Baader on my scope.

The basic mount works but isn‘t optimal.

 

Any further hints are appreciated.

 

Thanks and best regards, Karl

I had two and some problems.

 

Probably both were made on Monday?

 

The rest of my gear from TeleVue is incredibly good.

 

Very strange.

 

Regards, Karl

Not sure what your issues are, but the Starbeam has been around for a long time, and a quick internet search of reviews shows them very heavily weighted on the favorable end. If the design is faulty, it’s sure fooled a lot of very experienced users!

I sold mine.  I think the reason was it was too vulnerable to dew.  But the truth is I forget.  It was just one of those things that seemed like a good idea, but turned out not to be.  Greg N

I have one mounted on a 105mm fractor

I have taken it totally apart for a reason that escapes me now.

I fabricated a 4"  aluminum stalk to raise it up from the scope, my only issue was it didn't sit high enough.

.a tiny bit of BLUE lock- tight on the mirror screw should solve that problem of them loosening when you flip the mirror

Personally I like the function & astetis of the unit. 

I've had it for years. I use a quick point on a pronto & also use Rigel & Telerad finders as well

 

OT love the Zappa quote

Count me as another with zero problems.

I don't understand your first sentence, though.

The mirror screws don't relate to the illuminator thread, merely hold the threaded plug in place.

Try tightening the setscrews down, then a very tiny drop of oil on the hinges (one at a time) and they shouldn't loosen as you move the mirror.

Or use Buddy's idea of loctite on the screw.

I have never had an issue with mine either. I have the older design with the chrome battery tube.

I have 3 Starbeams and like them a lot. Never had any issues with them.

 

I removed the flip mirrors from mine, as I thought it was a bit of a gimmick. If you’re having trouble with your mirror connection, I recommend you try removing it and using without.

 

I also have 4 Baader Sky Surfer V. You can’t be having any trouble with those. That is a great design and easily mounted. If you need mounting assistance, maybe posting some photos will help.

I love the flip mirror. You can use it from several feet away.

Big event tonight. I really managed it to adjust my new Baader RDF using Alpha CMa as target.

 

But this device isn‘t the promised land either.

 

The two knobs that look like they are made to adjust alt/az are just caps that cover two poor head screws.

 

Too bad. I guess if I mount the device on a gun i won’t hit a target just 3 feet away or so

 

And if I touch this thing just slightly with one finger the whole glory is gone.

 

It is because it‘s fixed just with one poor tiny screw on a base that isn‘t made very precise.

 

But i guess that i‘ll figure out a more stable way to mount it.

 

Without Loctite, for sure.

 

It looks like amateur astronomy is my favorite waste of time and money now.

 

And BTW, my seeing isn‘t so bad tonight.

 

Best regards, Karl

Hmm.  Maybe the Telrad IS the best finder.

Are you speaking of the Baader SkySurfer V? Or the smaller RDF? My Baader SkySurfer V has proven to be the best RDF I've owned.

@zawijava: I was talking about the Baader V

 

@Don: Please send me the full metal edition. Black aluminum, anodized. Or even better the titanium edition

I just bought a Starbeam for my TV-76, and have the same problem.  The little collar where the LED threads into just spins.  Back it goes.

 

Also, the little metal plate on the TV-76 that has the serial number on it popped off.  The adhesive gave way.  The telescope has been handled very carefully and has not experienced deep cold.  Oh well, this I can fix.  Otherwise, the telescope is outstanding optically and mechanically.
