    Default How low can you go?



    Whist observing last night I decided to see how far I could push the power whilst observing the Hercules cluster, and I managed to get down to my 5mm e/p and the view really did justify me buying this e/p. I wasn't sure if this e/p would get a lot of use other than the odd night with perfect conditions observing the moon. But wow it really did seem to pop out last night along with tendrils of star lanes streaking out all around the cluster, it really did appear as I've never seen it before.
    I'm now wondering if there is anything else that would benefit from such high power.

    Eyepieces = Baader Hyperion Aspheric 31mm and 36mm. Baader Hyperion 8mm, 13mm, 17mm, 21mm and 24mm.
    Diagonal = 2" Altair dielectric diagonal.

    You can put stacks of power on M57 and many other planetary nebulae

    Just realised I didn't go as high as I thought as I forgot I was using a F6.3 focal reducer. Still the view was amazing.

    Clusters can take a lot of magnification I've pushed 496x on them which maxed it out with a F/4.4 setup.
    I think it could have done more that night.
