C5 vs. C102 vs. F5 6inch NewtPosted By Gary Davis |
Ron,
I to have a six inch f/5. The picture seems to be a bit off axis, showing the blue fringe and red fringe. Your eye will do this as well if you fail to position your eye in the center of the glass, not all EP's do this. Seeing could be the problem. Check each night to see if it gets better and don't rush to a conclusion, as a quick view of jupiter is sometimes mis-leading. How good is your star test ? I'm sure you know about cool-down and warm-up, right ? Also try your view overhead "jupiter just as the sun begins to set" as much as you can. Jupiter is getting lower in the sky with each passing day. I have no opinion on the C102 or C5. One thing though, is this scope an Event Horizon ? If so, you need a different primary for better images. By the way, do you have good eyepieces for your scope ? With more information we can help you further !!
