Από το site της Hotech:

 

"The Hotech SCA Laser Collimator comes with an innovative "Self-Centering Adapter" that automatically centers the laser and keeps it from that way to maintain precision".

Για την εγκατάσταση και απεγκατάσταση του laser υπάρχουν και σχετικά video στο youtube:

 

 

Τα πιο σημαντικά προτερήματα του συγκεκριμένου laser είναι ότι κεντράρεται ακριβώς στο σωλήνα του εστιαστή και ότι το laser διαρκεί για ώρες, αντίθετα με τα συνηθισμένα collimator της αγοράς.

Η παραγγελία έγινε πριν περίπου ένα μήνα και καθώς είχε εξαντληθεί προσωρινά, έφτασε πριν 10 μέρες. Κόστισε $120 + $44 μεταφορικά (έχω επισυνάψει ένα αντίγραφο της παραγγελίας από το order history του λογαριασμού μου στο συγκεκριμένο κατάστημα).

 

Έρχεται μαζί με μπαταρία και κασετίνα.

 

Τιμή: 75 ευρώ.

 

Ευχαριστώ,

Ηλίας (6972375266).

Hi Ilias,

 

Great choice. I too have one of these bad boys on order-should show up real soon. Now I will be able to collimate my SCT and Newtonians wihtout to much fuss.

 

For those of you who may be contemplating the purchase of a laser collimator, their web site has a few pdf files by others with additional information on the art of collimation which is helpful. Hotech's instructions are also very good. This link takes you to their collimator page http://www.hotechusa.com/collimator.html

Hi Fred! I hope you get yours real soon! Well, I was also very excited about this product at first. Wish I could say the same now that I have used it..

Don't get me wrong, this collimator is FAR BETTER than the conventional and mainstream laser collimators (orion, baader, etc), however not all scopes are created equal and mechanical and other issues can get in the way and compromise its use. In any case, I don't feel the hotech can substitute the classic cheshire or the fine tuning of a star test in the field.

My scope collection includes a large newtonian and a large SCT. I haven't tested the hotech on my C11, but on the other hand I never felt the need for such an accessory on this scope. Frankly, I think the star test is by far the best and easiest way to collimate a SCT. I check the collimation, every time before each observing session no matter what scope I use. The C11 rarely needs a touch and a fraction of a turn on the Bob's knobs to get it right.

I hope your experience will be better than mine with this accessory, both on your newtonian and SCT.

Clear skies,

Ilias.

Hi Ilias,

 

I do agree that a star test is the best way. I figure that one "tunes" the instrument with the laser collimator and then "fine tunes" the instrument with the star test.
