  • AWESOME!
Set: Telescope Style: RP-100
This was purchased for my grandson. I was impressed with the quality. This is a heavy made telescope and should last years without a problem. My son who has a very expensive telescope thinks this is a great learning telescope. You can clearly see the Rings of Saturn and everything is user friendly. Great investment for starters and intermediate users! Quality- low price - Can't go wrong on this purchase! ... show more

  • Optically decent, but mechanically - be good at tweaking
Set: Telescope Style: RP-400
I'm close to 30 years as an amateur astronomer, and 40 as a tinkerer. First off, the boxes were all falling apart when this was delivered. Everything seemed to be intact, but the COUNTERWEIGHT was completely missing. I cobbled a weight up out of stuff most people wouldn't have lying around. Have emailed Carson to get a weight. Might have to update about customer service. As for the scope itself, the optics aren't bad at all - much better than I expected. At less than 100x, I was able to make out the two equatorial bands and a hint of other bands on Jupiter, and the seeing wasn't all that great at the time. I pushed the scope to 200x (the theoretical limit, and then some) on Saturn, and it held the detail quite well! Keep in mind, I was not using the supplied eyepieces, but some decent grade Plossls from Meade and and others - and a Meade shorty 2x barlow. The finderscope is junk, really. Get a right angle correct image one, 6x30 or larger. A standard finder base (orion, and universal) will fit the holes that take the supplied finder, but you'll have to take out the three screws that hold the focuser assembly in place and remove it to get at the screw assembly thing.Didn't even try the eyepieces because I have a good collection of far better ones. I also ordered a better diagonal (the instructions call it a "corner" lens) because these cheap ones are not very good. The tripod is very stable - just needs a flat spot for a bubble level. The biggest issue, for me, was that the Declination lock bolt wouldn't actually lock the shaft, making for a tough time finding and staying on target. The end of the bolt wasn't flat, so I switched it with the too-short latitude lock bolt, and that fixed it. I suppose you could file it. Would I recommend this scope? Yes, if you're good at noodling out minor mechanical problems. In this hobby, one kinda has to. The scope I'd give a 4.5, but the mount gets a 3.5 (for poor hardware choices), hence the 4 stars. The packaging, however, was ridiculously bad. UPDATE: Customer service was on point - emailed Carson a bout the weight and they got it right out to me. Also...If you want to add a clock drive, it can indeed be done! Celestron Logic drive has the right gearing, but the mounting of it takes some modification that many people may not want to undertake. It's fairly easy to do though, and interested parties may contact me for details at [email protected] ... show more

  • It works towards the Moon but not quite for Jupiter
Set: Telescope Style: RP-400
Had to give it 3-stars. The packaging was soiled on the corners and edges and some of the individual white boxes that protects certain components during shipment were caved in. Luckily, I didn't notice any damages or scratches. Assembly is very straightforward. I tried it for the first time tonight knowing that Jupiter is out according to http://earthsky.org/tonight/moon-and-gemini-stars-high-in-south-at-nightfall-march-28. Viewing the moon is crystal clear using the 20mm lens and that was awesome as I can see its landscape very clear; however, Jupiter was hard to see even through the 10mm lens as it looks more like a fainted orange. ... show more

  • Disappointed :(
Set: Telescope Style: RP-100
All is see are stars the same as i could see with my naked eye. The telescope is very shaky even when i set it on my concrete patio. I spent $100 on this for my son. Its alright but definitely dont see any planets.

  • Good starter telescope
Set: Telescope Style: RP-200
My wife wanted this for camping. It sets up easy and gives you a decent view of the sky. There is no case with it, but for the price it is a good buy. We will get a larger telescope later once our son gets older. We don't have to worry too much about him using this one. It is pretty sturdy, and not too expensive so the risk are reasonable. ... show more

  • Carson't support is incredible
Set: Telescope Style: RP-200
Due to the weather there have been few days to try the Carson RP-200 telescope on the night sky. Unfortunately, there was a minor problem that Carson's support quickly addressed with a minimum of fuss.

  • This is not a bad starter scope
Set: Telescope Style: RP-200
i do not know who gave it a one star rating but they did not have the courtesy to write a review. And that says alot Few scopes at this price have slow motion controls and a finder scope. It is not a bad unit for wide field viewing and it is very light weight. Suggest better eyepieces and tripod/mount for those getting further interested in viewing the skies ... show more
