Hi Folks
I'm looking for some advice on illuminated reticle EPs for star aligning/guiding.
.
I recently purchased a Meade 12.5 mm illuminated reticle EP (MA12) and while the views through the EP were surprisingly good, there was no variable brightness control as advertised - it's only on or off. Most importantly, to bring the double cross hairs to focus one must turn the upper most EP section but after only one or two turns, this section starts to wobble from side to side on top of the EP. Also, with minimal force I can simply pull this focuser section off without unscrewing it. Similarly, I can also push it back on all the way without screwing it on. In fact it seems the threads do little and the only thing holding the focuser on is the sticky grease. I either have a dud EP or the quality of this EP leaves a lot to be desired.
Basically, I would like to replace it but the only options from the local supplier with the same/similar FL is the skywatcher 12.5 mm IR or Orion 12.5 mm IR. Otherwise, I could replace it with another Meade, which to be honest, I am reluctant to do.
It seems that the other main players are Celestron's 10mm IR, Lumicon's 12.5mm IR (seems expensive) and Rigel System's 12.5 mm Pulsguide. I am sure there are many others. I am interested in the Rigel System's EP mainly due to reports that the brightness control actually works but I can't seem to find any information on the quality of the EP - 3, 4, or 5 element plossl etc.
So I am keen to know if anyone has had experience with any of the EPs above or could provide suggestions on alternatives. What do others use?
Many thanks.
Steve
