I am relatively new to astonormy. I have a celestron Astro master 130eq with a focal length of 650mm. I have been able to enjoying viewing some of the planets and star clusters so far. I was considering purchasing one of the celestron x-cel LX eye pieces for getting an enhanced view of the planets such as Jupiter and Saturn Has anyone used these eyepieces and if so what would you recommend? Any help would be much appreciated.
Going through all my EP's which I need to whittle down, so I am selling the following EP's, all of which are in very good condition, if not mint;
Celestron Omni 6mm plossl - £10 + p&p
Celestron Omni 12mm plossl - £10 + p&p
Skywatcher SP 17mm plossl - £10 + p&p
Explore Scientific plossl 10mm 70 degree - £28 + p&p (sold)
TMB Planetary 2 4.5mm - £22 + p&p
Explore Scientfic 2" 25mm 70 degree - £40 +p&p
All owned from new, with end caps and original boxes (except the 2" ES 25mm EP which I can't find the box it came in sorry). Can collect if local, or will post in the UK with signed for 2nd class which adds £3.95 postage for each individual EP.
Thanks for looking,
Looking to sell (which I may regret eventually) my Meade 5000 40mm 2" 68 degreee wide fov EP. In very good condition, with original box and end caps. Excellent EP for nice widefield views. Works extremely well in all my scopes that can hold it. Would prefer collection, or willing to meet up within an hour or so of Hull if buyer willing to contribute to part of the fuel costs, or via post if only option (approx £11+ at minimum UK postage)
Looking for £80 (+p&p if required).
Thanks for looking,
EP is now Sold.
Having downsized to exclusively 1.25" eyepieces for financial reasons, I found myself missing widefield views. Recent price hikes mean the Ethos range are well out of reach, so I looked into alternatives.
First up on my budget list was Burgess Optical TMB 40mm 68 degree afov. I purchased this used last year and it is a very nice, relatively compact and lightweight eyepiece. In comparison with the grenade that is a 41mm Panoptic it is positively slender!
I've yet to use this under a dark sky where it would excel, but so far have used it to get a decent fov in my C925 from home and have been pleased with the results. I found this comparison with a 41mm Panoptic on line which makes interesting reading. I would be surprised if the differences were as marked as is described here. The description of a flat field also puzzles me, I understand it to be related to field curvature i.e. Where the focus point is consistent across the field, rather than related to increased magnification towards the edge. Any thoughts?
Next up on my list was a used 20mm Explore Scientific 100 degree. Last night was the first time that I had a good chance to use it, and I was pleasantly surprised. Looking at a variety of old favourites such as M45, the Double Cluster and other OCs such as M36, M44 etc, the contrast was impressive, sky background dark and star shapes consistent across the field. I guess the Tak at f7.4 is not a tough test, but these objects certainly looked great even under skies that were at best mag 19.35 on the trusty SQM.
Finally, I could not resist a new 30mm ES 82 degree. This has yet to have much of a run out except from the back garden, but I have every expectation that it will deliver good results. Hopefully I will get away camping to Dorset or Devon camping for a week or two this summer.
Effectively the 20, 30 and 40 go head to head with the 21mm Ethos, 31mm Nagler and 41mm Panoptic. It is curious why There is a 1mm difference in focal length across all of these eyepieces, given that the ES at least are pretty much direct copies I don't understand why they would differ? I'm sure that ultimately the Ethos range will have an edge under good conditions and in faster scopes, but for the moment I am content with what I have. I need to sort some foam for a case to put them in to add to the Show Us Your Eyepiece Case thread .
Due to further scaling down of my EP collection, I am now selling also my Televue 20mm plossl EP. In excellent condition with both end caps and original box. Looking for £60 (+£3.95 second class signed for postage), or can collect from Hull if nearby.
