SkyWatcher HAC 125

-----------------------------------

Am descoperit acest telescop, sau mai degraba obiectiv-astrofoto pe Aliexpress. Apertura 125mm, focala 250mm, reglaj de focus in fata.

I tested the HAC125 three years ago. We&#8217;ve were asked numerous times at NEAF about this scope due to the video.

 

We have no intention of bringing the HAC125 to the North American market. There are actually a few reasons as well:

 

1) You can only use 1.25&#8221; guide cameras with it. You are not able to use popular cooled cameras such as the 533 or 2600.

 

2) Focus is done via a helical in the middle of the corrector. There is no way to automate it and your hand blocks light when focusing.

 

3) You&#8217;re very limited on filters as they can only be 1.25&#8221; as they have to thread onto the front of the guide camera.

 

The telescope uses a very interesting optical design. I do hope the technology used in this telescope will be applied to others in the future. I would consider this a proof of concept for our ability to produce interesting reflecting type optical designs.

 

So while the HAC125 is very interesting it is quite limited in the modern era of imaging. I would see people getting this and being done with it a week later. But I do hope we see some of the tech used on future telescopes.

E buna de obiectiv pentru o camera de ghidaj. Sau sa faci selfi  :D 

Ma mira faptul ca totusi, dupa 3 ani, SW au pus-o pe piata. Totusi, cred ca s-ar putea motoriza focalizarea, folosind o curea si in motor pus la exterior. Dar chiar si asa, nu vad rostul ei, mai ales avand acest pret.

Mie imi suna mai degraba a experiment ratat. Prost gandit sau mai bine zis gandit cu picioarele.
Si ca intotdeauna experimentele fie ele reusite sau ratate sunt platite din banii astronomilor amatori.
Ca asa-i la vie!  :)

Poate SW vor lansa vreo camera cu senzor APS-C, sau macar MFT, care sa poata folosi tot campul vizual de 3,7 grade al ciudateniei, montata intr-un corp cu diametru de 4cm, hai 5cm. Asa s-ar justifica.

PS. Stiu eu niste indivizi cu un ego infinit. Cred ca le-ar place sa puna un ocular in acest telescop, si sa se vada foarte mari 
 :D  :D
