Che, viejo, mis hijos usan el mismo telescopio que tu.
There are two things you can do:
1, leave things as they are
2, make the most of a modest instrument to suck as much out of it as possible.
I would prefer No. 2. And it is not expensive.
You probably may have an old photo film canister with its lid. The Kodak ones fit perfectly into the 1.25" focuser. You can use this little canister to help collimate. Make a little hole (3 or 4mm) in both ends (bottom & lid) right in the centre. Insert the canister into the focuser and you will be able to gauge two things, how well centred the secondary mirror is (up and down and side to side), & if it is pointed in the right direction (rotation). Get the secondary right first, and the primary is even easier to work on. You can use the pictures Kal posted in his link to help fine tune even more. Total cost: $0.
I use one of these film canisters with my 17.5" scope! Nothing fancy and it works. I'm happy.
There are many threads here in IIS on collimation, and on the net. It is not hard and you will end up learning more, & be able to make the most of the gear you have too. If you would like more help, just ask,

Viva la Celeste!!
