craigb1970 Posted December 21, 2013 Share Posted December 21, 2013 I'm considering which low power (38/40mm)eyepiece to buy, the above being the likely contenders and I would be interested to know if anyone has compared or has any comments that might help me or indeed any other suggestions.I'm fairly new to astronomy and I bought a Celestron 8SE three weeks ago which I haven't had the opportunity to use it yet; and it's raining and blowing a gale again!!I'm not sure which mid and higher powered eyepieces I'm going to get but I will definitely be getting a 38/40mm soon.

rory Posted December 21, 2013 Share Posted December 21, 2013 X -cel lx only go to 25mm , a 38mm or 40mm would need to be in the 2" format I think. I can't advise personally on those focal lengths as I've never used an eyepiece of those lengths. Link to comment Share on other sites More sharing options...
bambuko Posted December 21, 2013 Share Posted December 21, 2013 If it is 1.25" than anything bigger than 32mm is pointless.Assuming you settle on 32mm - you might be interested in my experience of using Sky's the Limit 32mm Super Plossl: linkAfter the mods I am quite happy with it.

robhatherton Posted December 22, 2013 Share Posted December 22, 2013 I've got the 32 mm plossl from skys the limit and I'm very pleased with it. Well built and sharp and I certainly didn't need any mods. Link to comment Share on other sites More sharing options...
wookie1965 Posted December 22, 2013 Share Posted December 22, 2013 +1 for the 32mm Plossl from Sky's The Limit first eyepiece i use in my scope every time brilliant clear and sharp. Link to comment Share on other sites More sharing options...
craigb1970 Posted December 22, 2013 Author Share Posted December 22, 2013 Thanks for the replies and positive comments regarding Skies the limit plossl, also interesting about 32mm being the limit for the 8se, I assume that's because it's focal length?

Naemeth Posted December 22, 2013 Share Posted December 22, 2013 Thanks for the replies and positive comments regarding Skies the limit plossl, also interesting about 32mm being the limit for the 8se, I assume that's because it's focal length?It's not that it is the limit for an 8SE, it's that anything with a longer focal length than a 32mm 1.25" plossl will not be able to show anymore sky (the 1.25" barrel is the limiting factor here), it's only when you increase the barrel size to 2" that there is any point going above 32mm in focal length. By the way, a 24mm 68 degree eyepiece also shows the same amount of sky as a 32mm plossl, as the FOV is limited by the barrel.HTH Link to comment Share on other sites More sharing options...

Naemeth Posted December 22, 2013 Share Posted December 22, 2013 Hi Jonathan - thanks for the explanation which I understand: looks like there is a lot to learn, thank goodness for the forum and members giving good advice No problem, if you're going for a 2" eyepiece, go for something like this:http://www.firstlightoptics.com/skywatcher-eyepieces/skywatcher-panaview-2-eyepieces.html Link to comment Share on other sites More sharing options...
rory Posted December 22, 2013 Share Posted December 22, 2013 There's a good few low power 2" eyepieces around . Much would be down to your budget . Link to comment Share on other sites More sharing options...
CodnorPaul Posted December 22, 2013 Share Posted December 22, 2013 I have the 8SE (but now on an NEQ6) and changed the diagonal to a 2" Celestron XLT one - that would be my first purchase before thinking about low power. The 2" diagonal is superb quality, and due to the focal length of the OTA you do not need to spend a fortune on 2" EPs to get great views. The extra FOV is well worth it Link to comment Share on other sites More sharing options...
CodnorPaul Posted December 22, 2013 Share Posted December 22, 2013 Oh and as a separate issue - find a local astro group to observe with - you learn so much more and they will save you a fortune! Near Skelton there are some great dark skies so there must be a strong group (I work up that way) Link to comment Share on other sites More sharing options...
