Whenever I have come into large sums of money in my life, I always put half of it aside to spend on fast cars and the pursuit of loose women.
I put aside the other half to spend frivolously.

Quote:I can recommend the following eyepeices for the SCTs.The biggest issue that you will encounter is that the BVs will try to lock you into higher powers and for DSOs, someties you still want a low power for a big exit pupilFor this, I would recommend one of the two:The Televue 40mm Plossls. In the C14 (and you do want to binoview the C14) will give about the same exit pupil as a 41mm Panoptic. This is the best eyepeice for faint nebula or galaxies because this is about as big an exit pupil as you can get. The downside is that the apparent field is rather small, being on the order of 44 degrees or so.If you want to sacrifice a bit of exit pupil for a more pleasing apparent field and a slighly wider true field, then I highly recommend the 35mm Ultimas. The Televue has a 27mm field stop, but the Ulita has a 28mm field stop. It does not seem like a big deal, but in fact every millimeter helps with the C14. The exit pupil will be a bit smaller though, but the 49 degree apparent field to me is much more satisfying.I used the 35mm Ultimas more than the 40mm Plossls because of this.And of course this holds true in all of the scopes, but the ultimas don't have as good off axis performacne in faster scopes as the TV 40s I think.Next, the ES 24/68s work great. I used 17mm and 13mm Hyperions in the C14 as well. It is hard to use the 13mms though, because the BV imposed dimming does rob a bit of light, but I did use them on bright Globulars a lot.In the C14, my most used planetary pairs were 15mm and 20mm Plossls. You will find it hard to get nights of seeing that support more than the 15, and the 17mm Hyperions were not quite enough mag, though I have used them many times on planets with good result.The Hyperoins though are big, and if your IPD is tight or you are graces with a larger sniffer, they may be too tight.A "Split the difference" Alternative is the ES16/68. An excellent excellent eyepeice. This eyepecie could probably bump the need for a 15mm Plossl PairI use the 35mm Ultimas a lot though. They have very long eye relieve in the event that you need your glasses and they make it easy to take in the entire field.This is something that is not commented on much, but I find that even 68 degree wide fields make it hard to take in the whole field. You can't tilt your head with BVs the way you can in monovision withhout causing one eyepecie to kidney bean out.In general, the 50 degree AFOV eyepeicse actually seem more natural because you simply see the entire field without having to tilt your had.But I love my ES and Hyperions in the binoviewer and can recommend them.Not the 24mm Hyp though. Not as nice an experience as the ES 2468s.
Quote:Levine - If I was going to binoview with them, I would be tempted go with the smaller Leica zooms which have a bit smaller FOV but reportedly equal quality to the ASPH and cost half as much. My favorites are orthos/plossls/Brandons because of their optical quality and ease of use in the binoviewers. My core set is the24mm Brandon, 16mm ZAOII, 12mm Brandon, and 10mm ZAO-II. The more reasonably priced version would be the UO HD or volcano top style orthos in 9, 12.5, 18 and 25mm. For wider field I have the 24mm Pans and 13mm T6 Naglers.Also, if you have a 2X Powermate, it makes an excellent barlow for the MkVs with the Powermate T-ring installed (which also halves the length of the Powermate).

Quote:I have not yet purchased a second ASPH, so this is a best guess, As I have sucessfully binoed a pair of Meade series 4000 SWA 24.5 mm eyepiece with my 61 mm ipd, ( and the ASPH,s are close in diameter and shape to the meade,s ) I think about 58 + mm will work ( also my wife who is about 57mm ipd could use this setup). But much depends on your nose and forehead ridge shape.RexEDIT: I just looked up the diameter of the ASPH and it is 59mm so and IPD of 59 mm or more is needed + nose room!
Quote:Cool!If you do get two and bino them? some things to consider:the APM 1.25" adapters should have the least in-focus about 20 mm,The starlight adapter, maybe 33-34 mm.I like the Starlight adapter because it is removable without tools ( and I like to store the ASPH in its case which will not fit the adapter too). So it depends on how much infocus your scope has?Rex
Quote:Levine,Could you please measure the shoulder on your 1.25" APM adapter? ( the distance from the shoulder of the eyepiece holder to the top of the adapter)I am working from pictures to see how much this adapter raises the eyepiece above the top of the eyepiece holder ( My best guess is 12mm or 0.475 inch).Thanks,Rex
Quote:The 1.25" adapter is longer in the shoulder than the 2", as the bottom of the Leica has to fit in it and the leica is too wide to fit inside a 1.25 barrel.Rex
Quote:hmmm, the first set i have bought was two volcano top university orthos. a total cost of $110 these are sill the easiest eyepieces to use. Planetary performance is great as well. if i were to buy new eyepieces i would go for the Edmund 28mm rke pair Also some great info is on a thread going in the eyepiece forum labled favorite pair of eyepieces.
