    Default Vixen 130mm Reflector or 80mm Refractor for Beginner?



    Hi, I am new to this forum. I just bought my 15 yrs old daughter a Vixen R130Sf Newtonian reflector (130mm) with Porta II mount and aluminum tripod. The shipment just arrived but we haven't opened the boxes yet. I am now having a second thought whether I should have gotten her the Vixen ED80Sf refractor (80mm) instead (also with Porta II mount). I have done my research that both have good optics, relatively lightweight and easy on beginners. The ED80Sf being on APO is three times more expensive (and probably can produce sharper images) but can be used for astrophotography if she chooses to do so later. I still have the option to get a refund for the R130Sf and buy her the ED80Sf.

    Would someone help me to decide which one I should get? Is there any point of having both the Vixen R130Sf and ED80Sf if budget allows?

    Thanks,
    Uran The

    Stick with the 130mm reflector , it will show so much more than any 80mm scope no matter how good it might be , I know this because I have a viewing buddy with one of these sweet 130's on a GSO alt/az mount and it has awsome quality optics and build , I am impressed at how good it is .
    You made a good choice so get it out and enjoy its views .
    edit, the 130mm has 13200sq mm surface are compared with the 80mm's 5000sq mm , no comparasim really .

    Don't worry about astrophotography apart from lunar and planetary... This would need a mount costing at least twice that of the porta 2 az. She will see loads more with the 130 than the 80.

    So it's safe to open those boxes now.. Your daughter will not be disappointed..
    The only thing that you can find is miscollimation: A refractor mostly cannot be far out of collimation, but a reflector can..
    Mostly, telescope sellers do not collimate the telescope before shipping (which I would consider as a necessary service), so with reflectors,
    many people end up with a telescope that is not collimated the right way out of the box. And mostly not yet experienced, these buyers don't
    recognize the misalignment of the optics, and start to use that telescope as it is, and so don't see the full potential of that scope.
    There are many places on these forums where you can find details about collimation.

    I used to do many a public outreach for youth groups and set up multiple scopes (as many as 5 or 6). My R130sf on a PortaII mount was always the favorite over my Onyx 80 EDF on a CG5-GT with the kids. They seemed to "get it" better than the refractor on the goto and had a better time, got a better knowledge of how things worked and had more fun manually scanning the skies with the R130sf and the Porta II. I think the physical size of the R130sf was most of the fun for them. Kind of an aperture fever thing. The Vixen was one of my favorites too. A very good beginners scope with some very good views. My Ethos ep's make that scope very impressive.

    I know I'm late to the party, but I have a R130Sf and I'm very happy with it. I'm sure it has given you great service.
