- I've had the oppotunity lately to try out a friends Celestron
- SP-102 Flourite refractor and thought I'd toss out my
- opinions/impressions. This may contribute to ongoing discussions on
- the net, one on optics, the other on the SP mount.
- After spending an evening with the scope I came away disappointed.
- After hearing *so much* after the performance of apo-refractors I was
- ready to have my socks blown off. The scope was nice, but not mind
- bending - in the words of Public Enemy "don't believe the hype".
- The most disappointing thing was the lack of aperture. The
- Messier objects thru the 4" refractor were little more than fuzzy
- blobs. My Meade 8" SCT with good optics (the topic of much discussion
- on the net about 9 months ago - I sent my old one back with bad optics
- and they sent me a new one with good optics)'
- easlity trounced the refractor. Planetary images, during an evening
- of average seeing, looked comparable to me. Double stars were *much*
- better in the refractor. We easlity split Epsilon Bootes with the
- refractor. Nothing of the companion was seen in the SCT.
- I was generally impressed with the SP mount after hearing much
- bad about it. It was fine for visual observing. My frieNd wisely
- bought "shake-enders" with it - I was investment in my opinion.
-
- In summary:
-
- What I liked about the scope:
-
- 1. Nice dark background!
- 2. Really sharp images to the edge of the field! Before he had the
- motors installed we'd let planets drift across the entire field. It was
- quite a change for me to see a planet in focus at the edge of the
- eyepiece.
-
- What I didn't like:
-
- 1. Not enough aperture!
- 2. Difficult to use the slo-mo controls when looking thru the
- eyepiece.
- 3. What's with this portability thing? This scope was not what I
- would call Easily portable - a SCT is more portable (IMHO).
- 4. Expensive!
- 5. T%his is in fact the second scope - the first one was sent back
- because the optics were not up to par, and this one is going back too.
- The star test reveals a textbook image on one side of focus and slop
- on the other. Celestron has not been quick with the replacement scope
- either.
-
- If I knew now what I know (huh?) when I was first buying a scope I'd
- buy neither a refractor nor a SCT (but I'd choose the SCT over the
- refractor, hands down) I'd buy/build a Dobsonian.
-
- This has been my two cents worth.
