    Default Completed my SW SWA-70 (Celestron Ultima LX) eyepiece set (a mini review)



    These are the same as the Celestron Ultima LX model that most may be more familiar with this name. So I now have all from 22mm -> 5mm which works very well for my 3 scopes.

    I took the plunge after sitting on the fence for quite some time and purchased the (17mm) of the Skywatcher SWA-70 series after it's been on sale for a little while at First Light Optics. Hopefully it will arrive early next week and hopefully they'll forget to pack the clouds this time.

    I was finding the jump occasionally a little too much when using my 8" SCT with the reducer going from 22mm (58x) to 13mm (98x), either sometimes losing the object as it's drifted off while changing the eyepiece or too much difference in magnification for more sensitive (faint) objects. All being very closely par-focal and all having 2" insert barrels make it a doddle to switch from one to another without faffing about with adapters to go from 2" to 1.25" barrels.

    I've built up this series except for the 32mm (which is the only EP that gets mixed reviews and I don't need anyway) since buying my Celestron C8 back in Autumn, 2014. They are heavy especially the 5mm which is a beast but have a remarkable build quality and the twist up eyecup is so comfortable for long periods of time. Also very handy is the rubber coating which definitely helps when it's cold and much easier to take in and out of the diagonal.

    The long eye relief also makes it nice for long periods of observation and have not yet suffered from eye-strain using these EPs. Colour shows very well with stars and with the planets it never fails on Jupiter and Saturn showing true colour in the cloud bands and Mars the other night looked a lovely natural colour. I have not suffered any astigmatism with my C8 at f/6.3 nor the 80ED and 120ED at f/7.5, the brightness showing well up to approx 95% of the field. For me, the 70 degree field as about right although I've not tried any greater wide-field EPs.
    SpyderwerX and Bigzmey like this.

    Congratulations! I was curious about that EP Line, but both Skywatcher and Ultima are hard to come by in US. Do you know how different they are from SWA Q70 design?
