Pig Posted February 2, 2013 Share Posted February 2, 2013 Dazed and confused What is highest magnifiation I can expect to get a decent crisp contast form with my ƒ/10 ?(1500 /152mm)The capability of the scope is approx 314 X. Cough CoughConsidering our climate inhibits this to about 200 X, is it better to go for an 8mm or 7mm ?7mm =214 X8mm = 187 XI am planning on getting an X-cel LX to match all my other eyepieces.however, I am prepared to get a different make / type and pay more if it is worth it.How does the Luminous rate for double the cost, any ideas ?

John Posted February 2, 2013 Share Posted February 2, 2013 Assuming the conditions are good, the scope is in good collimation and properly cooled, and depending on the object being viewed (all can have a significant impact on image quality) 200x or so should be usable. As these factors can and do vary night to night and sometimes hour to hour, it's very useful to have a slightly lower power to drop back to - this often gives better views, especially of objects like Jupiter.So, ideally, both a 7mm and an 9mm would be good to have in your eyepiece case - you then have options Link to comment Share on other sites More sharing options...
