I have a Skywatcher MAK 150mm OTA. Recently I read that it would max out at a magnification of 375. With the focal length of 1800mm I figured that a 5mm eypiece would do the job giving a magnification of 360. Since then though I have been advised not to go beyond 300, I was hoping too buy an Orion Stratus 5mm as I have been very happy with the 17mm I bought last year. The closest I can get in Orion is 8mm, yielding only 225. However if I go for the max magnification of 300 then the nearest quality eyepiece I can find is a Meade 6.7MM eyepiece. As a relative newbie I need advice.... Thanks.
