Short Tube Reflector Collimation

Hi Guys,

Im looking for some advice re the collimation of a Celestron Nexstar 114 SLT.


Its a short tube style telescope with the built in barlow. I have a laser collimator which I have tried to use with the 114 but the inbuilt barlow spreads the beam into a big blob, should I be worrying about collimation on a small scope like this? The view through the eyepiece looks 'ok'
but it would be a shame if i'm missing out on an improved view because of dodgy collimation.

I also have a 10'' Dob which is fantastic and I am able to collimate this with the laser no problem.

The Nexstar was an expensive mistake, I got sucked into buying it for the go-to feature and didnt realise it really isnt worth the extra money for the fancy gadgets. However, i still bring it out from time to time as a quick grab and go instead of hauling the dob out for those nights when I just want a quick look at something and for that its not too bad.

Great site btw, been browsing here for a while now and always seem to find answers to anything I need to know here. I've done a search of previous threads for a similar problem but couldnt see anything, apologies if its already been covered and I'm just to blind to see it.

Cheers
Mick
