    Smile Choosing Eyepieces



    Hello,

    I'm a newbie... I would like some help with selecting some eyepieces. I own a Meade LXD55 f/4. I bought it about 6 years ago but have hardly used it for various reasons. I am now ready to get back into it but I still only have the stock eyepiece. I have a budget of about $300. Following is what I had in mind;

    Meade 8.8mm Series 5000 1.25" Ultra Wide Angle

    Meade 3x Series 5000 4-element Ultra TX "TeleXtender" for 1.25" eyepieces

    Meade #905 variable polarizing filter

    I have read the Starware book and also I have read the link on Astronomics.com and these were the choices I came up with.

    I am looking for a good starter combination of a basic lense and barlow that will give me the ability to look at the moon, planets and fairly decent deep space, in that priority sequence. I am 50 years old, so I would like some good eye relief and I also understand that an exit pupil of about 5mm is ideal for this age group.

    Do you have any better recommendations within this budget?

    Thank you for you help!

    Welcome to the forum, WayNerd1. I don't know your scope, but I can suggest that you might also want an eyepiece with a long focal length as well. Something in the 30mm-35mm or so range, just to see some wide fields and help finding things.

    Yes, a 5mm exit pupil is nice for us oldies, but you can get good views with smaller exit pupils, too. Below 1mm, though, the brightness really dims fast. Also, many times higher power doesn't show you any more detail than you would see at medium power. One night recently while looking at Saturn in my 8" SCT, I could see more surface detail at 162x than I could at 320x. Better contrast.

    Just some thoughts. Cheers.

    ... absolutely understand the polarizing filter for lunar viewing and really bright objects ..

    ... you might consider a 10mm and a 40mm EP along with a 2x Barlow ... that would give you effectively a set of 5mm, 10mm, 20mm, and 40mm Eps that would carry the range of use you are asking ... and best-yet, when you "Barlow" the 10mm and 40mm you will keep their respective eye relief ...

    ... just my opinion ... your mileage may vary ... hth ...

    Hi WayNerd1,

    Welcome to Astronomy Forum.
    What is the stock eyepiece?
    I would think that the Meade 3x Series 5000 4-element Ultra TX TeleXtender would not be as useful as the 2x version.

    Hi waynerd , welcome aboard the forums . I think you could save a few dollars and buy an off brand polarizing filter . As far as the eyepieces goes have you considered the series 5000 plossls , they have a 60 degree field and are great build quality . The 9mm is only 69 dollars from meades website . That would save you more for a nice barlow and a second series 5000 26mm plossl eyepiece . There only 89 dollars . Is your scope a reflector ? (schmidt-newt) . Your focuser is only 1.25 ? Your stock eyepieces are MA 9mm , 25mm ?

    I'm not clear here on what the scope is. It would have to be a f/4 Newt or SN but what aperture? This will have some bearing on EP selection.

    Meade LXD55 - Model SN-8: 8" f/4 Schmidt-Newtonian — With 78% more light-gathering power than the SN-6, the 8" Model SN-8 roughly triples the number of observable objects in deep-space and resolves extremely fine planetary detail as well: ... blah blah blah ...

    ... that took a tad bit of digging ... Hey Way ... is this the correct scope??

    Hmmm well I don't have any experience with SNs at all but at that short a focal length I'd guess that the scope could be "fussy" when it comes to EP selection. Best get advice from someone who actually has the same scope, or take the scope to a star party and see if some of the other guys there are willing to let you try a few of their EPs in it.
