Hi everyone,

 

I just obtained an older SVS 130 Astrograph (#029). It has an Stellarvue Optec forcuser and a flattner reducer attached. Maybe somebody could help with an explanation of the different parts that I have here....

 

I'm  fairly experienced in  AP...GT81/ASI 2600 etc but I'm not familiar with this older equipment...(vintage). I'm wondering how much of it will work with NINA for example....

 

I also noticed that the flattner/reducer has no numbers on it....what is the reducer percentage...??

 

How about a mount?? I was thinking maybe an Ioptron CEM 60?

 

Any comments or opinions concerning this scope would be helpful....mostly for AP maybe a little visual.

 

Thanks in advance.

my sv flattener has no identifying marks on it either;  if u can contact the prev owner, the order form or invoice should have it on there.  If not, they have a reducer flattener for the svx (f7) on line; assuming ur scope is the same focal length, i 'suspect'  the specs are similar;  it's .75 reduction. Or contact Stellarvue. Or take 2 pics; 1 with f/r the other without; measure the difference (pixels v. pixels)

Plate solving with the FF/FR attached will give the focal length.

Hi, 

 

I think I found the manual for this telescope - 

https://www.stellarv...nual SVS130.pdf

 

 

Per the details available online it is triplet with 3 element corrector., F5 and Focal Length 655. 

May be its a F7 telescope with 0.72x reducer. I am guessing.

Thanks all......seems Stellarvue only sold 12 of these and they were sold before they initiated in-house optics.  Thanks for pointing me toward the manual...

I have this scope (SN #8).  It is currently using NINA to capture images in my observatory in the yard.  The Optec TCF-S3 focuser is excellent and uses the Focus Lynx drivers located here: https://optecinc.com...rs/lynx-family/ This scope has been an excellent performer for me.  Pay attention to the correct spacing (found in the manual: 69mm) for the flattener and you will get a flat field large enough to cover a full frame chip.
