Everyone thinks collimation is hard i did i was just like you once you have done it you will say what was all the fuss about no doubt the secondary mirror will be in the right place when you get the scope if it is then it will take you two minutes collimate it im not joking, if secondary is out take longer but come back i will post a great tutorial the one i used and it will make things much easier, dont let collimation put you off getting a great light bucket like the 200 dob.

Suggest you might also struggle to see a big improvement by moving to the Mak? Moving to the larger aperture dob you certainly will see a big difference. If you are purely interested in planets then the Mak my be the right choice.

I found collimation confusing to start with but there are a number of good guides out there including some excellent video tutorials that will get you through it.

+1 on the dobsonian, a Mak will even have some downsides (cooling time, obstruction, shift, and IF collimation is neccesary it's a pain in the ear).

A 8"f/6 won't be as critiical regarding collimation as the 5"f/5 is, and as said it's easy once you get the hang of it. A small Mak on goto mount is a nice idea but won't show more and as they are usualy made with a 1.25" focuser you won't get nice overview magnifications as anything other then a 32mm Plössl will get cropped/vignetting, a 40mm plössl has the same real field and just a smaller aparent field of view...

If it's just about the goto, the mounts can carry the 130/650 ota;

no need to buy the small Mak.

If it's about the tracking, a dobsonian and a eq plattform are one solution.

Good luck choosing a telescope!

so it's time to get rid of the skywatcher 130 and move to something a little better any recommendations?

the 200p dob has been suggested ?  or shall I splash to cash and go for Skywatcher Skymax 127 SynScan AZ GOTO

what puts me off the dob is the collmination

have you not collimated your 130M? It is a newt isn't it? or am I making a comlete div of myself. I'd say get a collimating tool (staying clear of laser v cheshire) and have a play with your current scope. you'll soon see how easy it really is :)

Collimation really is easy, and once you've done it once or twice then you're fine :).

How about getting a Cheshire and try on your current scope?

Oh, and the Skymax won't really be an upgrade, as the aperture is pretty much the same as your current scope (3mm less).

plenty vids on youtube showing you how to collimate, I expect its far easier than aligning the goto on the mak, I know I just sold mine as its a pain in the bum, by time I got it up and running it dewed up, I would rather just point and look without the faff!

+1 for Schorhr comments regarding a Mak.

Looking at the FLO image of the Skymax 127, it looks like the collimation screws are easy to get to. I have an ETX105 and to get to them you have to seperate the 'flip mirror' assembly from the main tube.

Mak's and SCT's do give a narrow field of view. So if you are a lunar or planet observer than they are great. For deep-sky then I would not recommend one. The only reason I went down catodioptric road was because of the storage space the take up and ease of transportation in an apartment without a lift/elevator and that I observe lunar and planets, (and have four sodium street lights and a supermarket car park in my neighbourhood).

You Know you want 10" ;-)

But to keep it serious... Make sure you are aware of the size regarding storage and transport.

This German shop utilized non-standarized humanoids to demonstrate the dimensions of the different telescopes.
