Choosing astronomy eyepieces & filters starts with a practical fork: are you trying to change magnification, or filter light? A Barlow lens and a nebula filter serve different jobs, and the listed 1.25-inch and .965-inch formats create a second decision. Start with the task, then the format, then the listed price. That approach keeps a lower price from steering you toward an accessory built for a different purpose.
Quick take
The 1.25-inch Barlow sets are the choices for shoppers who want several magnification labels in one purchase. The .965-inch Shorty Barlow is a more focused single-magnification route, while the No.82A Blue Nebula filter serves the separate job of filtering light. The four listed prices span $15.68, but price should break ties only after the accessory type matches your intended use.
Listed price comparison
The listed prices run from USD 10.99 to USD 26.67. The bars show relative price position within this comparison, not optical performance or suitability.

Decision matrix
- Several magnification choices in one set: The 1.25-inch 2X 3X 5X Barlow Lens 3Pcs/Set and the 3Pcs/Set NEW 1.25-inch 2X 3X 5X Barlow Lens both name 2X, 3X, and 5X.

- Universal compatibility wording: The 3Pcs/Set NEW Barlow uses Universal for compatible brand, compatible model, and compatible series.
- Single 3X Shorty in .965-inch format: The 965\" 3x Shorty Telescope Barlow Lens states that format and magnification directly.
- Light filtering: The 1.25-inch No.82A Blue Nebula filter is the dedicated filter choice and identifies optical glass.
Product notes
1.25 inch 2X 3X 5X Barlow Lens 3Pcs/Set US
At USD 25.85, the 1.25-inch Astronomical Telescope Barlow Lens 2X 3X 5X Eyepiece Lens 3Pcs/Set US gives shoppers clear construction detail to weigh: optical glass, aluminum alloy, full green coating, dust covers, and M42*0.75 photography threading with a built-in M35*1 thread. Those specifics make it a sensible match when thread and material details matter alongside a multi-magnification set. The limitation is the three-piece format; if one magnification is all you need, two included lenses may go unused for you. Its stated focal-length entry is under 10 mm, another configuration detail to consider.
3Pcs/Set NEW 1.25 inch 2X 3X 5X Barlow Lens
At USD 26.67, the 3Pcs/Set NEW 1.25 inch Astronomical Telescope Barlow Lens 2X 3X 5X Eyepiece Lens is the direct alternative for shoppers who want three labeled magnifications in a set. Its fully green-coated specification gives a concrete reason to choose it when that coating detail matters. The limitation is the $0.82 gap above the other 1.25-inch three-piece set, and the three-lens format may be more than necessary when the goal is a single magnification. This is a straightforward choice for someone who prioritizes the stated Universal compatibility wording for brand, model, and series.
965\" 3x Shorty Telescope Barlow Lens
With its .965-inch format, the 965\" 3x Shorty Telescope Barlow Lens is aimed at a shopper seeking the single 3X magnification named in its title. The Shorty design, 2-1/2-inch total length, and both caps give concrete reasons to consider it when a compact single-Barlow setup is the priority. The limitation is narrower choice: it names one magnification rather than the 2X, 3X, and 5X range on the two 1.25-inch sets. At USD 11.99, it sits near the low end of the price spread, but that figure should not decide the purchase ahead of the .965-inch format.
Astronomical telescope 1.25 inch No.82A Blue Nebula filter
Astronomical telescope 1.25 inch No.82A Blue Nebula filter Telescope filter serves a different purpose from the Barlow lenses. Its title specifies No.82A Blue Nebula, while the product uses optical glass and has a 1.25-inch diameter. Choose it when the aim is light filtering or a named color-filter accessory, not a change in eyepiece magnification. The limitation is role-specific: it does not provide the 2X, 3X, or 5X magnification choices named by the Barlow sets, so it cannot replace them for that task. At USD 10.99, it is the lowest listed price, but it is a different accessory type.
Final recommendation by use case
For several magnification choices plus detailed construction information, choose the 1.25-inch Barlow Lens 3Pcs/Set US. If Universal compatibility wording is the deciding attribute, choose the 3Pcs/Set NEW Barlow. For a single .965-inch Shorty use case, the 3x Shorty Telescope Barlow Lens fits the stated brief. For filtering rather than magnification, choose the No.82A Blue Nebula filter. In short, select by task first, format second, and price only among accessories serving the same task.
