    It is all personal preference, but I don't care for the red-dot finders. My big scope is an Orion XT10 go to and I have two finders on it. First I use a Telrad to get in the vicinity of my target, then a 9x50 RACI to zero in on it. By then the target is in the field of view of the eyepiece. As stated, personal preference, so it will be interesting to see what others like to use.
    Peace and clear skies,

    I have either a Multi-Reticle Reflex or Telrad red dot finder on each scope. Then I have an optical finder too, 9x50 or 8x50. I use the red dot to get me in the area and if need be, I then use the higher magnification optical finder. Just like Ken said, it's all about personal preference.

    The best way to go is to have two finder scopes as Paul indicated: One - red dot (or Telrad, Rigel, etc.) to point the scope roughly to the right area, and 2d - 9x50 or 8x50 RACI to zero down on your target location.

    I have Orion's 9x50, but similar RACI from other brands works fine to.

    Hi Pranpro. All excellent advice above. A RACI finder scope and a Telrad or Rigel second finder scope is a very popular combination for many users. I am partial to the RACI finder. Here is a photo of my XT12i with a 9x50 RACI finder. I hope this helps Pranpro, and the best of regards.

    I go with the RACI alone, I can usually sight down the tube and point it close enough to put the target in the RACI. But this is only on my longer focal length scopes. With my scopes of 700mm focal length or less, I do not use a finder at all, the scopes field of view with a low power EP is wide enough that I don't need a finder. I do have a red dot finder that I use with the little 90mm Mak that I occasionally use for some planetary views. Put the dot on Jupiter and it's in the field of view.

    Refractors kick arse precisely because they don't hide behind excuses. That is, they have no obstructions to hide behind. - Jon Isaacs (CN)

    I've been very pleased with the Celestron illuminated reticle RACI I added to my SCT. The soft red glow of the double crosshairs is perfect. Even at max intensity it's not as bright as a laser, so don't really need to tweak the brightness at all.

    I am not yet as good as Ozman at sighting down the tube, so I will echo what others are suggesting. When I first got my XT12, it only had a RACI on it, and I quickly found myself frustrated trying to find stuff. It was easy as soon as I got the star/planet/target inside the RACI, but frustrating before then. It did not take long before I added a red dot finder to the XT12. With the red dot finder, I can reliably find my target (if it's naked eye visible) or my starting point (if I need to star hop). The RACI then works very well for starhopping and precisely positioning on the final target.

    If I were forced to choose one or the other (for some reason I could not possibly have both), I did a lot of starhopping in the eyepiece of my XT6. I would probably choose the red dot finder over the RACI if I had to choose one or the other. Fortunately, no one has forced me to choose, so I happily use both.
