opinions on orion skyview pro 8
« on: December 23, 2017, 10:54:41 PM »
I've a celestron nexstar 102 refractor.  Would a orion skyview pro 8 be a good addition to see things that the refactor?

Indeed. However I would go for a more comfortable 8" Dobsonian (available as a fully manual, push-to or even go-to telescope)

That would be a good choice. Our first telescope was a 6-inch, f/8 Newtonian on the SkyView Pro mount. The package was good enough to get us through the Messier catalog. I suggest you also buy the motor drive ($166) and the polar alignment scope ($60). Motorized tracking is a great convenience. You need a good polar alignment for the setting circles to work accurately. Note that there is a learning curve to use an equatorial mount effectively.

There is also a GoTo version of the SkyView Pro ($1,130). If you are considering it, I think there are better choices. One would be the XT8g GoTo Dobsonian ($1,050) which would actually be preferable to an equatorial mount for visual observing. Other equatorials would be Celestron's 8-inch Newtonian on their Advanced VX mount ($1,099) and Orion's Sirius 8 EQ-G ($1,400). Both the AVX and the Sirius are decent beginner mounts for long exposure astrophotography.

Big newtonians on GEMs are pretty cumbersome and the ergonomics aren't the best (tube rotation is an issue, among others). It isn't a bad choice, but you might want to consider a dob instead if you don't care about goto and tracking, or an SCT if you do.

A Zhumell 8" dob is hundreds of dollars less money to buy ( $399 w/ free shipping vs $699 ), has much better accessories and at f/5.9 is easier on eyepiece quality.

I agree, an 8 inch dob will probably be a better choice.

The advantage of a GEM is the tracking and when I started into this hobby a GEM did seem help me make a connection with how the night sky appears to move. The other advantage with the tracking is moving from low to high magnification, almost never lose the object in view. I think a 6 inch f/5 reflector is a very easy to work with and it is an easy set-up and breakdown.

However, with an 8 inch reflector the advantages of a GEM diminish. With a GEM one needs a fairly substantial mount, at least an AVX and even that might be pressing it a bit. Having to carry around 25 pounds of counterweights wears thin after 5 or 6 outings. Also, the focuser can often be located in uncomfortable places; hence, one has to rotate the tube. Observing, setting-up and taking down is a lot more work than using a Dobsonian. An 8 inch Dobsonian requires relatively little physical effort to find and observe objects, and perhaps even more importantly to set-up and breakdown the rig.

The Dobsonian mount does have one disadvantage: Dobs whole. Objects directly overhead or within about 10 degrees thereof can be difficult to locate but this does not in my opinion detract much from the advantages of the Dobsonian, at least compared to having an 8 inch reflector on a GEM.

If you go with the Dob I think you will be pleased.

Edit: As Howard states, cost is another big advantage of a dob.

<p style="margin-left:40px">I had a SkyView Pro mount and liked it a lot. However, for Orion's current asking price it doesn't really compete with Celestron's AVX if you know you want go-to.
<p style="margin-left:40px">
<p style="margin-left:40px">I agree with the others who state that an equatorially mounted Newtonian is problematic unless you have rotating rings (expensive). If you're in the northern hemisphere, then the eye piece will be in neck breaking positions when viewing in the south unless you can rotate the telescope within the rings. I tried it. I bought rotating rings.
<p style="margin-left:40px">
<p style="margin-left:40px">I also agree that the best bang for your buck is an 8" Dobsonian. I like the Orion IntelliScope system (push-to). Unfortunately, Orion now has a policy of not supporting second owners of their products which makes buying used Orion gear risky. New, the XT8 is $389 (100% manual), XT8i is $660 (push-to)and the XT8g is $1050 (go-to).
<p style="margin-left:40px">
<p style="margin-left:40px">There are other companies that make 8" f/6 scopes, I'm not trying to push Orion. Orion just happens to have three variants of the same scope with different levels of electronic assistance.
<p style="margin-left:40px">
<p style="margin-left:40px">The 8" f/6 Newtonian is a venerable scope design that will show you lotsin the sky and keep you busy for a long time.

I found this one on craigslist and it has the motor drives, and the cost is relative since they guy has given up the hobby due to age and has only used this telescope 3 times do to the weight and set up time.  On the goto idea could I mount is on the celestron goto mount that I all ready have for my 102?

The 8 inch F/5 Newtonian is way too much for the SLT mount. The 130mm F/5 Newton's an is marginal at best.

The only advantage to the SkyView Pro package over the Celestron AVX, in my opinion, is that you can build up over time. Since you're thinking of buying used, perhaps you just keep the drive motors for a while and decide if you like the mount and scope combination. If you decide in the future that you want go-to, Orion sells a go-to upgrade kit ($580)for the SkyView Pro that's easy to install and pretty accurate once you get it optimized. I liked the installation I did.

Of course, if you know you want go-to, the AVX is cheaper over-all.

Another advantage of the SVP is that it has slo-motion handles.

Even though the SVP has a solid reputation it is rated for 20 lbs. and I think that this mount will be marginal at best with the 8 inch f/5 Newtonian. The AVX will be a better match.

But, as was stated above, an 8 inch dob is the best choice for visual observing.

550.oo or BO, yeah, that's a good price, and much easier to move about than the SVP set up
Make sure the mount works, you can just do a mock alignment in the day, see if it goes through the motions.

That appears to be an original Nexstar 8 or maybe an 8i. It's an older model and I am not sure about the level of support available for it. If something as simple as the hand controller were to fail, it maybe that a replacement would be difficult to find.

Uncle Rod Mollise is the guy who knows this stuff. His used CAT Buyers Guide is a good read
