We returned this item for credit. We were disappointment with the quality for the cost.

I use the 3 and higher for imaging Planets, thet 2X can be used for doubling the power at the eyepiece. The 127 eq is a great scope you should have lots of fun. I had a C5 at one time loved it.

There is no magnification with this T-Adapter is good for prime focus....where your camera is receiving light directly from the telescope...the "magnification" will be from the scope itself and no eyepieces...if you want magnification...you need a T adapter that will allow for use with a barlow lens...which is mainly used for planets...as deep sky objects are far too big

Yes, this would be a very good telescope for watching the Bay. When you use the 20 MM eyepiece that comes with the telescope it inverts the image so you see what you are looking right side up. The 20 MM eyepiece gives you 50X and if you use the 3X barlow with the telescope, you get 150X. The 4MM eyepiece gives 250X, but this eyepiece is only good for astronomy, because if you use this eyepiece to look at the Bay, what you will be seeing will be up side down.

Yes, you need to buy the t-ring of the type of camera you have, Canon or Nikon. and here's a bonus if you have just a regular barlow piece I've combined them in the past for even further zoom.

If your telescope uses 1.25" eye piece then yes. The quality of the barlow is very good so I like to use it whenever I can. I enjoy looking at the moon with it because you see a lot more detail including seeing the shadows of the mountains when you vewing a partial moon.

You can get eye pieces that provide more magnification but for the XT4.5 it won't enhance your viewing. I would instead get a Barlow lens to double the 2 you already have as I found the 10mm w/ Barlow is much better than buying something like the 6.5mm I picked up. In fact, I find I use the 25mm w/ the Barlow more than I do the the 10mm.

yes i have three and right now I'm installing # 2 be carefull with camera installation it is really easy to break the lens cover. They do work great

The one lens is but not the other two. They still work. I will look and work more with them in the spring.

I personally dont own a barlow but ive heard its best to not get one and just to get a more powerful lens

I don't see why not. I use mine all the time with my Orion 130ST. The Barlow lens should work on pretty much any reflector or refractor for that matter. It slips into the eyepiece socket on the scope and then your regular eyepiece fits into the Barlow. It does make the lens stand out from the scope another inch, but just rotate the scope on its mount to get a comfortable view. BTW, I've been so impressed with this lens that I also ordered a 5X Barlow to see if I can really bring Saturn in. Good viewing and Happy St. Patrick's Day!

It is not any better other than it in not broken. It took quite an effort for my ring to get cracked. I have used the repaired lens with the plastic mount for nearly a year now without any issues. Good luck. (it was much better and cheaper than a new lens.)It took me about 1 hour to replace it. -- tiny springs and screws -- 7 screws if I remember.

I have one you can use it in 3 parts I like it Some my not on older lenses . Hope it works for you.

Try the ocular first and if you need more power then add the barlow. Personally I do not like barlow lens and you will have around 155X with the 8mm. That is a nice power for the C-5. Generally my oculars cost around $350+ each and are a single mm because the lower priced oculars degrade the optics far to much for me. The C-5 is a fine instrument but most cripple it with poor quality oculars.My C-5 can handle a 4mm ocular beyond that the quality is lower than I generally want and remember it is only a 5 inch instrument. If you want more power then get an 8 inch interment.

A 6mm eyepiece will give you about 75x magnification. I get better views of Jupiter in my scope with 4mm and 3.8mm eyepieces at about 115x. I don't like using a Barlow.

It depends on both the scope and the eyepiece. While the Barlow will increase the magnification by that amount you don't want to exceed the resolving power of the scope since you'll lose image quality and not gain additional detail. There are web calculators available that can help you figure out magnification and resolving power.
