    Default Meade LS8 + Meade 26mm 5000 series vs Baader 8-24mm Zoom



    Hi all,

    First time poster but many years a reader. I'd like your input on the following setup. I recently inherited a Meade LS8 scope which has amongst the eyepieces a Meade Series 5000 1.25" Plossl Eyepiece, this is currently a d/c eyepiece.

    Question1:
    I've been debating purchasing a Baader 8-24 zoom hoping that it would give me a brighter and clearer view of some star clusters, M-series objects, and planets (Jupiter and Saturn this time of year). My other eye pieces include a 20mm and a 9mm from the Meade 400 series so there isn't a large investment in glass at the moment.

    Question2:
    Would it be worth upgrading my diagonal to that of a 2"? would this give me more light into the eye piece and therefore give me a brighter/clearer object in which to zoom up to 8/9mm? Or am I being limited by the f8 and simply need to upgrade to a 10+..

    Much appreciate your comments ahead of time!

    Clear Skies,
    Belg

    Welcome to the forum!

    The Baader zoom is one the highest regarded zoom EPs, but I would stick with QUALITY dedicated focal length EPs, they will give a better performance and most will give a wider field of view (this depends on their design).

    The scope has a 1.5" baffle at the rear port, so switching to a 2" diagonal only gives an increase of .25" and not .75". This increase does allow for a wider field of view but does not increase the perceived "brightness" of an object, for that you need more aperture (larger scope).

    The f/# doesn't affect the perceived "brightness", it reflects the focal length of the scope compared to the aperture and accounts for your field of view. The f/8 scope has a wider field of view than a f/10 scope of the same aperture because the f/8 scope has a shorter focal length (which is the real determiner of field of view). You can effectively increase your field of view with a focal reducer.

    The f/# is much more important to imaging (AP), not so much for visual observing.

    Thanks for the quick response!!

    I messed up my specs above... the Meade LS8 is a 8" scope that has an f/10 on it...

    So the apparent brightness that I'm currently seeing today can only be increased by collecting more light... ie get a bigger scope. Getting higher quality eyepieces relaly won't give me much of a boost...

    Quality EPs will not increase the perceived brightness, but will give you a crisper and clearer view than the basic starter EPs. You will see your targets better, just not brighter. Getting a bigger scope and using the same starter EPs will give you a brighter view, but not a crisper more detailed view, for that you do need better EPs.

    With its SCT design, the LS8 has a relatively narrow field of view, and can be disappointing for looking at star clusters, particularly Open Clusters.

    I'm not sure about the current design of the Baader Zoom, but it used to be commented on how narrow the field of view was at the lower power, which wouldn't help.

    So, you may want to consider a 32mm EP instead (or look for a Focal Reducer), particularly if you're thinking of getting good views across the full range of Messier objects.

    Makes sense. I come from the photography world where I learned to invest my money in the glass first and then the bodies as they were forever changing. Due to that experience that’s why I was thinking of going the way of the Baader zoom and then over time invest in more prime EPs. Thoughts?

    For the cost of that zoom you can get 2-3 maybe even 4 of those prime EPs. For about half the cost of the zoom you can get an ES 24mm 68 which is an excellent eyepiece for the scope and gives the widest possible field in the 1.25" format.

    How far can I push the FOV on eyepieces with this scope? I’ve seen some 80-100 degree EP but not sure if that’s overkill on this scope..

    To get that large of a degree to fit in the observable field, those designs of EPs start to become 2" at shorter focal lengths. The ES 14mm 82 is still in the 1.25" format, but the 18mm 82 is 2". The 14mm and 11mm 82s would be useful, and occasionally the 8.8mm 82, anything shorter is too much power, anything longer is 2". Any 100 degree EP in the 1.25" format is really pushing the power too high for most situations.
