Celestron X-Cel Series 1-1/4" 2.3mm Eyepiece

Celestron X-Cel Series 1-1/4" 2.3mm Eyepiece
If you are looking for an eyepiece that excels for planetary viewing, then Celestron's X-Cel offers the unique features you are looking for. A 6-element fully multi-coated optical design, the X-Cel utilizes extra low dispersion (ED) glass on its most highly curved surfaces, to minimize chromatic aberration that can hinder sharp planetary views. With a wide 55° apparent field of view, and a large 25mm clear aperture the X-Cel is one of the most comfortable eyepieces to use. Every X-Cel eyepiece is parfocal with each other, meaning little or no focusing is needed when changing from low to high power. The X-Cel comes with soft rubber eyecups and a durable plastic case. In addition, if you are an eyeglass wearer, you will enjoy the 20mm eye relief available on each of the X-Cel focal lengths. Threaded barrels accept 1-1/4" Celestron thread-in filters.

Celestron 93327 X-Cel Extra-low Dispersion 2 x 1.25 Barlow Lens

Celestron 93327 X-Cel Extra-low Dispersion 2 x 1.25 Barlow Lens
Barlow lenses offer an easy, economical way to increase the magnification range of your eyepieces. A Barlow lens doubles the magnifying power of your eyepiece by doubling its effective focal length. For example, an 18mm eyepiece used with a 2x Barlow lens would have the magnifying power of a 9mm eyepiece. It's like having two eyepieces in one! If you're looking for an affordable way to achieve high-power viewing of the moon and planets, double stars and even close-up views of terrestrial subjects, a Barlow lens is the answer. Barlow lenses mount into either your telescope's focuser or visual back

Carson 5" BigEye Magnifier

Carson 5" BigEye Magnifier
Carsonâs BigEye has a 5" over-sized viewing lens and is likely the biggest of any hand-held magnifier available! But it's not the heaviest, thanks to its high quality crystal-clear acrylic lens. Outdoor Green color.

Setting-Up a Small Observatory: From Concept to Construction (Patrick Moore's Practical Astronomy Series)

This is the book to tell the intermediate-level amateur astronomer what he needs to know about observatories. It draws on the authors practical experience and that of many other experienced amateur astronomers.

It is an ideal complement to Patrick Moores More Small Astronomical Observatories which is a compendium of ideas for different observatory designs. Setting-up a Small Observatory covers the details of design, siting and construction once a basic type has been decided upon.

It is written in a way that is equally applicable to the USA and UK (where there are slightly different building regulations) and deals with matters that are basic to building and commissioning any amateur observatory. Uniquely, David Arditti also considers the aesthetics of amateur observatories fitting them in with family and neighbors, and maybe disguising them as more common garden buildings if necessary.

Every amateur astronomer who wants a purpose-built observatory (and that is most of them!) will find this book absolutely invaluable both during the planning and the construction stages.
