Celestron 93436 2 Inch Luminous 2.5X Barlow Lens, Silver

An important rule to remember: When it comes to adding anything to your optical path in astronomy, don't shop "on the cheap". You will be sorely disappointed with the results. If you can afford a Televue, do it. If not, the Celestron Luminos is the best bang you can get for your buck. 4 elements. This thing is not only gorgeous for visual observation, but it's outstanding for astrophotography. Strongly recommended.

Construction excelent. Performance still unknown, while waiting for clear skies

Solid, not too heavy. And could get focus on a nextstar slt 130 with astro camera without issue. Have to be careful though, looking at Jupiter with this and an eyepeice was quite bright, needed to use a filter. However I so suffer from light sensitivity, so probably not an issue for others

Well I’m not enjoying it so far because the moon is to big in that lens and I have yet to view Saturn or Jupiter, can’t seem to find them.

Truly what I wanted. Have an 8 inch Dobsonian and a 28mm deep view lens, great light capture but always wished I could get in closers with a 2 inch eyepiece. The 1.25 isn't as enjoyable for me.. of course I was worried about losing light and increasing distortion as those of you reading this are too I'm sure... let me put you at ease, this is amazing. Truly amazing. Turned it on onions belt and got perfect views of the nebs on the sword. Great close ups of jupiter, perfect clarity, perfect flattening across the lens with no awkward edge distortion. I was really happy with tonight's stargazing and this has definitely been the purchase I hoped it would be. If your on the fence, buy it. If your not even in the market for thos.. buy it. Just buy it. You won't be dissapointed.

Muy buena visión

I bought the celestron 2.5x barlow to do some planetary work. I looked over a number of reviews and have to disagree with them on several points. Weight - the barlow is not heavy. weight is similar to a typical eyepiece if not lighter. Build quality - quality is quite acceptable. I would call it good. Exterior - is polished, metal with a rubber friction ring for grip and handling. I prefer a dark exterior but that is just my preference. Style - fits in with the other Celestron Luminos equipment. I would rather a simpler style but this is what is available. Optically - acceptable, clear images, not distorted. The telescope, eyepiece and equipment you use with this will certainly factor in to the optical performance. I am using a high quality triplet refractor with good 2" eyepieces. There are better barlow lenses out there but at a higher price point. So in summary, At this price (i got a discount) i consider it a very good buy, and certainly acceptable for my uses.

First night out, I paired this with a University Optics plossl 55mm & a Meade 5000 UWA 20mm. The results were great! This mid-range barlow has a quality 5 element design so it has nice color correction for the price. Because it is a 5 element design, it provides some field flattening effect to my 13" dobsonian, Without me having to buy a paracorr :D

Deze Barlow geeft ontzettend veel vervorming, enkel het center van het beeld is scherp. De foto in bijlage is gemaakt met een Canon EOS R , foto van setup voeg ik toe. IK heb getest met en zonder coma corrector, maakt geen verschil. De meegeleverde Barlow 2x van 30 euro geeft betere resultaten. De 1.25" oculairs van Skywatcher en Omegon passen niet in de 2" naar 1.25" adapter?

Monté sur mon skywatcher 200 /1000. Le rendu est très bon. Par contre attention au poids si vous avez des gros objectif en plus.

This barlow is better quality than expected. Mechanically speaking, it is very solidly made and has an interesting appearance. Optically, it is superb with flawless coatings, excellent resolution, and a completely flat field with edge to edge sharpness while using any sized eyepiece with it. It is really light weight and not overly large either. Better quality than a Meade series 4000 2x barlow that it replaced. I am completely satisfied with this barlow. Highly recommended!

Es una lástima que tenga que devolverlo. No se ajustó a la focal de mi telescopio y no hay forma de lograr un enfoque correcto. Sin embargo, es un muy buen producto, desde el empaque se siente que no es un producto barato. Llega con una bolsita de piel (o vinipiel) para su transporte, lo cual es buen detalle. La idea de que el adaptador de 2” a 1.25” ya venga incluido, es Perfecto. Simplemente no fue el correcto para mi equipo, pero es un excelente producto.

اذا عندك تلسكوب سلسترون لازم تكون هذي القطعه عندك صح انها غاليه بس اعتبرها من اهم الاشياء اللي لازم تقتنيها👍
