    My personal opinion ....

    1. A collimation cap (unless the scope comes with it). Lasers are notorious for being uncollimated themselves causing a lot of problems for beginners. A cheshire+sight tube is the best option but has a steeper learning curve. A collimation cap is the cheapest and easiest to use option.

    2. RACI.
    2.1 It is best to have a reflex finder like a Red Dot or a Telrad along with the RACI.

    3. A 1.25" 2x Barlow, if both your EPs are 1.25". If you can get a Barlow where the bottom lens element can be taken off and attached to an EP you get 2x and 1.5x with it.

    4. Eyepieces (maybe after the first 3 months). It is better not to rush into eyepieces, try out the ones that come with your scope and figure out what you like watching and what EPs will work best for it. Better to save and buy some good EPs, something like a 2" ES 82 deg 18mm works well with my 8" Dob. EPs outlast scopes, so well worth buying good ones.

    All of those will be useful and expand your scope's abilities and ease of use. Not sure what the quality of the eyepieces that come with that scope are, but I was recommended to pick up 12 & 26mm plossls from GSO as the first upgrade to my scope and I haven't been disappointed yet. They have good quality optics and provide a well rounded arsenal of low to high power use without breaking the bank. Assuming your scope doesn't come with a Barlow, grab yourself a 2x Barlow. Again, GSO is probably the best choice for an affordable solution here.

    One thing I seem to notice people mention when it comes to dobs/newtonians is that they don't always come with the best focusers. It could be worth looking into a multispeed focuser, especially if you plan on doing any higher magnification use. I know from having a refractor, crayfords can be a headache to fine tune at higher magnification if they don't have a delicate finesse. I would also second ozman's recommendation of an adjustable height astronomy chair. It's a bit of coin, but worth every penny as it allows you to change observing position in a snap. Hope this helps.

    All that said, if I had to sum it up for immediate upgrades I would lean towards the chair, collimation tools and RACI finder. The rest will be more useful as you get experience.

    Just an update guys. I had a new 12.5mm plossl today and tomorrow I will receive a new celestron 2x barlow lens and a collimation cap. I will have my new 200p dob on Thursday. Then I will save a few quid a week for a 9x50 right angle finder. Thank you all for your help and advice. I appreciate it.

    I will look into the chair. My father does some great carpentry so maybe I can get him to put something together for me.
