Will a collimator help or let ITE do it ?

I`ve had my Intes (M603) for just over a month now and i have never been able to go over 100x without the image going soft. Both Jupiter and Saturn are great until i push beyond this limit. I`ve ditched the diagonal,no change, i`ve collimated using Polaris, secondary was only off by a smidge.Are my mirrors out of alignment with the mechanical axis and will a laser collimator help me to line them back up ?
Thanks for your help !!!

If seeing conditions have been decent, something is wrong - Maks have fewer collimation problems than SCTs, and the image should be clear and crisp well into the 200Xs.

Seeing has`nt been the best for several weeks but i see no more detail in my 6" than i could in my 3" refractor.

Find a mag 2 or so star high in the sky and focus on it at 150x or so. Compare the image to the Pickering Seeing Scale to see how stable the air is. If the image is dancing around wildly (Pickering 1-4), seeing is most likely the problem. If the image is stable (Pickering 7-10), do a star test. Lot's of info here on star testing if you do a search. Basically, move focus in and out until you see about 5 rings and compare the images. Rings should be round and concentric on both sides of focus. If they are not, you may have a collimation problem.

These Intes Maks are renowned for a couple of things - being excellent optical performers; and taking a very long time to cool down. The bigger versions come with built-in fans to facilitate cooling.

It is important to allow the scope to cool to the outside ambient temperature before use. If possible, leave the scope outside from the evening onwards, and/or store it in an unheated garage or shed.

Both sides of focus are equal in appearence. i.e. intra and extra are soft at the edges, showing hard to distinguish concentric rings. This is after cooldown period.

Pass on sending it back to ITE...too risky! Try an artificial star. The seeing conditions will be great and you can take your time!! or try this method first.... http://www.mira.org/...ures/collim.htm
