Daz Type-R Posted January 31, 2012 Share Posted January 31, 2012 Hi Guys. After being spoilt by Kim's ep last Saturday, now looking to get one of these rather than 4-5 different ep's. A few questions if I may..... 1, Parfocal across the entire zoom range. - does that mean regardless of the magnification you choose, you will not need to re-focus? 2, Includes both 1.25†and 2" barrels - threaded for filters. - does this mean that the ep is a 1.25" but it fits in both the 1.25" and 2" barrels, or does it mean it is a 2" ep that can be reduced down to a 1.25"? Cheers all. Link to comment Share on other sites More sharing options...
Guest Kheldar Posted January 31, 2012 Share Posted January 31, 2012 1. Yes (though Parfocal is often stated and not always entirely accurate. Kim can probably tell you better.) 2. It's a 1.25" EP with an extra wider collar so you can fit it in the 2" holder. Link to comment Share on other sites More sharing options...

BAZ Posted January 31, 2012 Share Posted January 31, 2012 Is this on a shopping list Daz? Link to comment Share on other sites More sharing options...
Daz Type-R Posted January 31, 2012 Author Share Posted January 31, 2012 Yes very much so, I was going to get 4-5 of the BST explorer ep's that you suggested a while ago, but though for the same money (or near abouts) I could get the above in one ep! Hence the Hyperion questions and the counter weight questions, the weight of Kim's ep pushed my scope over the edge!!! Link to comment Share on other sites More sharing options...
BAZ Posted January 31, 2012 Share Posted January 31, 2012 A very nice and versatile eyepiece. It saves messing about changing them. Link to comment Share on other sites More sharing options...
Guest Tweedledum Posted January 31, 2012 Share Posted January 31, 2012 If the zoom is like my 5mm prime Hyperion, removing the field lens (first element) turns it into a true 2" eyepiece and changes the focal length to a useful 17mm for the SCT. Is that the case with zoom Martyn / Kim? Link to comment Share on other sites More sharing options...

Guest Mark Payton Posted January 31, 2012 Share Posted January 31, 2012 This is my only EP at the moment and it is great, I am looking now for something in the 32mm arena and then I will be sorted (for now). Link to comment Share on other sites More sharing options...
Brantuk Posted January 31, 2012 Share Posted January 31, 2012 All correct - it's a 1.25" and you can put a 2" collar on it. You don't need to refocus if the focuser is locked and loaded - just twist the zoom collar for extra mag (works between the click stops too). However if the focuser moves slightly then a small adjustment may be neccessary. The fov narrows a little as you zoom out to 24mm but nothing that has ever worried me.

catman161 Posted January 31, 2012 Share Posted January 31, 2012 I love this eyepiece! First used it over at kims on a Friday nights observing and fells hay was it, I needed one! Mines on back order with FLO,they are hoping to get some in soon. Easily the best price I could find. Good choice Daz Link to comment Share on other sites More sharing options...
Daz Type-R Posted February 3, 2012 Author Share Posted February 3, 2012 Ok, it has arrived today and I totally forgot how much it weighed. Would I be best slotting this into the 2" focuser slot as I can change my ep's from 1.25" to 2", would the 2" be a tighter fit? Just a bit worried that it may wobble / fall out if I put it in the 1.25" adapter of my focuser. Or am I being daft? Link to comment Share on other sites More sharing options...
Brantuk Posted February 3, 2012 Share Posted February 3, 2012 The 2" barrel works fine with mine so you should have no worries - but the only advantage is a firmer fit - especially if you hang things like cameras off it. The eypeice is still 1.25" though Link to comment Share on other sites More sharing options...

The eypeice is still 1.25" though Thanks KIm, I was hoping you would see this post. Yeah it was the firmness of the fit that I was worried about, constantly touching the EP to zoom in and out, I would of prefered a snug fit that the 2" would of provided. next daft question, how does it fit? I have taken the 1.25" attachment off but i cant see where the 2" screws into, does something else have to come off? Link to comment Share on other sites More sharing options...
Brantuk Posted February 3, 2012 Share Posted February 3, 2012 Do you have the 2" barrel or the FTR? You can tell them apart cos the 2" barrel has a locking ring on it (much like the 1.25" barrel). The fine tuning ring has no locking ring and is meant to vary the focal length of the single field stop Hyperions. The threads are different.

Daz Type-R Posted February 4, 2012 Author Share Posted February 4, 2012 Sorted it thanks Kim. I hadn't noticed there was another adapter on the ep, removed that and the 2" adapter fitted straight on. Had first light with the new ep last night, I can't believe how much of a difference it made over the stock ep's. Link to comment Share on other sites More sharing options...
catman161 Posted February 4, 2012 Share Posted February 4, 2012 Jut don't look through any of Kim's televues! I have and that's my basis if comparison now! Like Kim said, I've seen televues far too early in my astronomy days . Link to comment Share on other sites More sharing options...
Daz Type-R Posted February 4, 2012 Author Share Posted February 4, 2012 Lol, yeah, I'm not even going there. If I were to spend 3-400 pounds on an ep the wife would kill me, I just managed to get away with £174 worth of Baader! Link to comment Share on other sites More sharing options...
Brantuk Posted February 4, 2012 Share Posted February 4, 2012 Really does make a difference eh! I couldn't believe it first time I put the Baader Zoom in our old 150P - it was like a new scope - just suddnely sprang into life. Since then I've been hooked on saving for better ep's Link to comment Share on other sites More sharing options...
Guest Space Beagle Posted March 8, 2012 Share Posted March 8, 2012 This is one of those eyepieces that I look at and think that I really would like one, but then have to be sensible and look at my ep case and realise that I really don't need one! I know for a fact, that when funds allow, one will appear as if by magic, good grief my will power is useless! Doc Link to comment Share on other sites More sharing options...
