Celestron RACI Finder Scope to replace RDF

[daveangie0110]

Hi All

I have a Nexstar 6SE and i hate the RDF that came with it i find it hard to align my scope precisely, i have seen a Celestron RACI finder scope which looks very good, and i have also read that it is better to use then a RDF if you live in a light polluted city as i do, can anyone tell me the pros and cons using this as a RDF replacement please.

Thanks

Hi Dave,

The RDF is quite simple to use, and is probably the easiest to align with your scope. The disadvantage is that it is easy not to get to the same viewing point physically with your eye. Also there is no magnification there.

A RACI saves your back   and will provide an amount of magnification (you have not told us which one you may choose). Fundamentally you still have to accurately align your scope with the finder of whichever variety you choose.

Thanks for that I prefer the RACI but I want to make sure it's worth the £100 price over the RDF, and what benifits it will give me

Hi Dave,

At that cost, it is worth looking around for a used one have a look on the classifieds here or on astro buy sell.

Thanks for that, as you can tell I am a newbie at this, can you tell me the benefits of a RACI I have also read that if you live in a light polluted city they are a must

Hi Dave,

Raci  is---  Right Angle Correct Image - so the view through is the right way up, so its easier to move your scope without working out which way is up or right - left . Also as it has the right angle, the eyepiece of the viewfinder is 90 degrees to  the telescope tube, it really does save your back!

As for light pollution, to complicate things a telrad is very good too!. Stick to the RACI first!!!
