richbyers Posted June 10, 2010 Share Posted June 10, 2010 was looking at a SW super MA 3.6mm EP for my 130p truss dob for observing moon and planets. Im using a 10mm as my highest magnification at the moment. Is the 3.6 a good EP? with my focal length the max i could use would be a 2.5mm or 5mm + 2 times barlowthanksrich Link to comment Share on other sites More sharing options...
lunator Posted June 10, 2010 Share Posted June 10, 2010 Hi RichFor the Money I would go for an orthoscopic, apparent field of view is about the same and the ortho will give a better view. You can pick them up S/H for about £20.CheersIan Link to comment Share on other sites More sharing options...
michael.h.f.wilkinson Posted June 11, 2010 Share Posted June 11, 2010 Agreed, a good second hand ortho or even plossl would be better than the super MA. Link to comment Share on other sites More sharing options...
