I'm looking for a new x2, 1.25" barlow as I have to think just about any will be better than my stock skywatcher one and I have narrowed it down to about 2 or 3 but the difference between them is one the TelVue is an achro and the X-cel or Vixen DX are apo's.
What is the difference if any between the choices?
I purely want this as an upgrade from the SW for solar, lunar and planetary imaging but only having ever used my old one I have no experience of anything else.
Maybe there are other options just as good that I don't know of?
Any ideas and recommendations would be greatly appreciated.
edit: I should add that the price of the TelVue is my upper limit so a powermate is probably out of the question.
