Orion Sirius Plossl 1. Select a Model 6. Email Friend. More Info Specs. Orion Sirius Plossl eyepieces have great features and are priced to please! Design Design. Different eyepiece designs allow for a wide range of features, depending on the needs of the observer.

Orthoscopic and Plossl designs can provide a great quality image with a standard field of view, but may be difficult to use at higher powers while wearing glasses due to the short eye-relief. Long eye-relief designs have more elements and can be more expensive, but work very well with glasses, even at higher powers. Wide angle designs provide a larger view of the sky at the same power as a standard eyepiece. More complex designs can combine all these attributes together in a single eyepiece.

Barrel size. Coatings Coatings. Number of elements. Filter threads. Parfocal Parfocal. Parfocal refers to an attribute of an eyepiece set where little to no focusing is required when swapping out one eyepiece for another. Barrel security recess Barrel security recess. The barrel security recess is a shallow groove or depression cut into the 1. In the event the thumb screw holding the eyepiece in the focuser becomes slightly loose, the eyepiece will not fall out because the tip of the thumb screw will catch on the lip of the security groove.

Blackened lens edges Blackened lens edges. Blackened lens edges in eyepieces and refractor lenses prevent unwanted light scatter inside the tube. This results in higher image contrast. Rubber eyeguards. Body material. Warranty Warranty. The eyepieces where very well protected in a big cardboard box not a jiffy bag am pleased to say and lots of foamies. Note to FLO perhaps use a environmentally safe 'foam' and not a plastic based one?

The eyepiece - Celestron 15mm Omni is a very nice product, I have a 40mm in my collection - I have yet to try it as the sky has been shy hiding behind rain loaded clouds! I think they are made by GSO and look like the Meade series and if so are a very good eyepiece for the price. I would definitely use FLO again and sincerely wish them all the very best for the future. I bought this as a first step in updating the standard eyepieces suppled with a m f6 refractor. I wanted something that was glasses friendly for the family and allowed a nicely composed view of wider subjects like the Pleiades.

I am very pleased. It feels and looks well made. Its not very heavy so doesn't unbalance the 'scope. The view is lovely, nice and wide and the stars look like bright pinpoints - across the fov even for an f6. The contrast is subjectively nice. The silvery body is nice as it allows it to be seen in the dark. The eyecup flips up and there is plenty of eye relief. The eyepiece arrived quickly and was very well packaged to ensure no harm could come to it in its journey.

This is a great addition to my range of lenses, providing a useful wide field of view for observing the stars at the beginning of my session or throughout! I have bought a range of these over time covering the 6, 9, 12, 15, 32 and They are good value for money and work well. I have recently bought my scope from FLO and purchased this eyepiece along with it.

It is better for clarity than the two that were provided with the scope. Some items that are showing as in stock are in stock at our holding warehouses, not at the shop. To double check the stock levels at the shop, please contact us on or sales rothervalleyoptics.
