New BST Starguider?

I use a 3mm eyepiece quite often with my ED120 and ED102 refractors. It's good for splitting tight doubles and examining fine detail on the Moon when the seeing conditions are good. It's below 3mm that I've found problems as I have some floaters in my observing eye that become too distracting when I've used, say, a 2.5mm eyepiece.

The TMB Planetary series and it's clones have had a 3.2mm in the line up for some time and it's quite popular.

StL haven't I think sold it before about now, I got mine from 365Astro about 3 months ago and there were no available at StL then as I looked. Nice purple, and mine it doesn't say Starguider just ED2. Also just squeezes into the box.

I bought mine for a short focal length scope and it works fine on that, but if looking at 200P's and similar then the focal length will deliver too much magnification.

Suspect 3.2mm is a bit too short for most uses.

Much the same as John, I use the 3mm Radian in my shorter scopes 805mm  -1m, it gives a very high power but it's good on Mars when it is closer to us, Venus the Moon and Saturn also handle this well. I did a review on the use of the 3mm and I was rather taken aback to find that tight globular clusters (M15 if I recall) can handle this too, though a dark site and good seeing are a must.

Moon maybe?!  :smiley:

I had a opportunity to try out the EDII 3.2mm (mine is marked 'StarGuider' as from StL) last night as it was such a clear sky, in my C100ED f/9 and must admit I was dubious about the scope and ep's ability to reach 281x and give a satisfying view, but looking at a good clear Moon last night I have to admit I pleasantly surprised when craters came into view on the terminater, in fact STUNNED, I had gone straight for the 3.2 without using a low power to edge in.  What a surprise!  I believe I was looking at the smallish crater (51km across) called Pallas and a related mountain range spilling off from the centre and it looked like grated cheese.  The brightness of the Moon was slightly dulled by the small exit pupil (only 0.36mm in this case), but I have to say I was dead pleased with the results, great for those rare nights, next stop Jupiter when I get the chance, but just for the Moon, this is a keeper.

The 3.2mm version I've seen on the web was 'Photon' branded ( thats' my belief) although only marked as ED 3.2. If the price is right, for such a difficult choice of eyepiece, I may get one, just  not sure my ocular case can accommodate any more, I'm pretty sure my collection is complete .

If only  it was marked BST Starguider  :wink:

The ones on ebay are marked Starguider I think.

Alan still seems to get some of the BST's in marked Explorer, think he mentions 2 on the site at present.

Have a 3.2mm with just ED on it so I may ask if he can lay his hands on one marked Explorer not Starguider as it would then match the Explorer set I have.

After looking at the Moon with  my  WO & BSTs last night. I 'm not certain now if I need a 3.2mm EP. So, at present, being undecided, I'm going to order a fishing rod instead, especially with the weather being pants for astronomy ?

Hi Charic, I too was undecided, that's why I left it so long, I think it is sensible to leave it for now and reconsider when the weather is better.

Robin.... how  time flies,  new rods AND EPs have arrived since the last entry (collecting and testing some Plossl brands)

The 3.2mm  does indeed work well on the Moon at 375x  and like yourself, poor timing and weather conditions preventing any further tests.   I still haven't found the 'C' Rock ?  at this magnification :grin:
