    Default best barlow for my new to me 127mm mak



    any recommendations for a barlow to add to an ORION 127mm apex? all i have as far as eyepieces is the stock 25mm and an orion 7-21mm zoom that came with the scope. I know the barlow keeps the apparent FOV better than a zoom lenses. Already upgraded to a GSO RACI and a dielectric diagonal. What a difference the diagonal made. Now ill be adding a 32mm and a barlow. Best brand as far as optics go? GSO makes barlows but are there better quality optics out there that wont break the bank.

    Best brand as far as optics go, Televue.

    The GSO barlow is a good barlow. For the quality and the cost, you would be hard pressed to find a better value.

    Is there an optical difference between a shorty and regular Barlow ?

    I've not seen any visual difference between them. I tend to prefer a short one because it doesn't put as much strain on the focuser and keeps the EP at a better height for me.

    Hello all,

    the shorty Barlows enjoy an increasing popularity in the visual astronomy.

    I have recently purchased the Baader triplet Barlow, matched for the Baader BCO orthos. It is believed to have higher transmission of light than the APO Barlows.
    I am still not through even with the basic tests, but the Baader triplet Barlow looks like correcting the CA in red - something looked for when observing the planets.
    Best,

    Some of the shorty barlows are too short and could introduce optical artifacts into the system. However, GSO shorty barlow is a good choice and give you two magnification factors 2x and 1.5x.

    GSO 1.25" 2x "Shorty" Achromatic Barlow Lens # GS2BL

    GSO also makes good quality Plossls, since you are looking for 32mm EP

    GSO 1.25" Plossl Eyepiece - 32mm
