    I bought the 8" SCT in July and I am still waiting for my rebate. They had not started the instant yet and it was still mail in. Also it comes on the EQ5 Pro mount not the EQ6 as someone mentioned.

    I do have a question, Would you get better views of planets with this 100 ED scope or with their 8" SCT? I have the SCT and my skies are terrible for "seeing" but given that I don't get very good views of Jupiter or the Moon, not clear, always somewhat blurry. You can barely make out the bands on Jupiter no red spot or any detail for that matter and the moon, always just slightly out of focus no matter how you adjust or what eyepiece strength you use.
    So I don't know if I am getting my best out of the 8" with my rotten ENCINO CA viewing which is on a balcony over a lighted swimming pool, lights all around it. OR if there is something not right with the scope. and wonder if I would get better CLEARER more focused and detailed view with the 100mm ED Skywatcher.

    Under very bright lighting an 8" SCT is not the best scope. It handles lots of light poorly because of the design of the scope and the larger the scope size the more the background light will effect viewing [bigger SCT = more light to obscure the target]. Use a dew shield even if you do not have a dew problem. Some of the light may be able to directly hit the correcting lens.

    As to the ability of a scope to perform in bright seeing conditions, the 100 ED is much better, it will yield more detail and darker background. Views of bright objects like the moon, planets and many stars will be much better. Under bright seeing conditions DSOs could be another matter, the 8" SCT can gather more light, however, the 100mm will yield better contrast, and 100mm ED OTAs require much shorter cool down time. That could mean the difference of the beginning of your viewing session starting at 9:00 P.M. for the 100mm ED and midnight for the 8" SCT.

    Note: When observing in bright light, to keep stray light from striking your eye, place a thick dark towel or coat over your head while observing, with any scope.

    Before you purchase a new scope I would take yours to a dark area under good seeing conditions [stars twinkle very little is often a good sign] just for a test, if the scope still shows poor images, there is something wrong with the scope. If you are not sure how to test the optics in your scope I would take it to a shop and have someone check it out, or if under warranty, send it back to the factory with details of the problems.

    Give your scope two hours to cool down, if the images are better but not up to what they should be, let it cool down one more hour and view again. Take a lawn chair, some star chart and binoculars to keep you busy while the scope cools down. Use a red light for reading or looking for things in the dark. If you do not have one, purchase an inexpensive, plastic tool chest to put your diagonal, eyepieces, lenses, and other important items that will collect dew [I even put my star charts in the chest, nothing like handling wet paper at night...]

    Using a red light is important because it does not interfere with your night vision. White light will destroy your night vision and you will have to wait up to 45 minutes to get it back.

    Thanks Swing, it is true I can take out the ED 100 Sky-watcher or similar refractor and let it quickly cool down and view almost immediately (although I keep it outside now even with the mount! - sorry i get lazy and want quick viewing if i have the time!) here is a pic (the OTA / scope is in its box just to the side out of the photo):



    I guess the one draw-back of that 8" beaut of scope (and great price now) is the cool-down time. If you have it outside early in the evening or in a shed/garage, you should be a bit quicker off the starting line. Just need a bit of planning even with a scope with some draw-backs.

    The only (or one of the biggest) draw-backs of the ED 100mm is its aperture, I miss my dob light bucket and the 8" SC can really get a lot more light than the ED 100 refractor so if you cool it down, or keep it cool most of the time in a cool place it really will give you some spectacular views.

    Arwen don't forget to try EQMOD... it really is much better than the hand-controller.

    Nice mount, however, I do not see any counter weights, do you put them on prior to viewing, or is the camera angle such that I cannot see the counter weights?

    Unfortunately I do not have anywhere safe to put a mount such as yours. And, I have a problem lifting anything over 25 pounds, even if it is compact, so, with an EQ mount I would have to make several trips to put a scope together, something that I do not want to do. At my age and health a grab and go is what I need.

    I was disappointed to find out that the recommended computerised go-to, grab and go mount for my 100 ED Sky-Watcher [according to Astronomics] is the alt-az iOptron MiniTower, however, it cost about $800 U.S. after shipping. Much more than I can afford to spend at the moment.

    Hi there, yes the mount usually has weights on it that time i guess i left it off.

    if you are looking for grab and go, im not sure what to suggest. I guess i would go for a small mak OTA and a eq2 mount or eq3 if pushing it.

    not sure what others suggest?
