The Astrozap AZ-117 Flexi-Shield® is a flexible dew shield designed for the Celestron NexStar 5 SE, with a notch cut to clear the side-mounted dovetail bar. It's the easiest upgrade you can make to extend observing time on dewy nights.

More observing, better contrast

On a compact 5" SCT the corrector plate fogs up fast. The Flexi-Shield creates a pocket of slightly warmer, still air in front of the optic and blocks stray light from the surrounding environment, resulting in longer sessions and crisper views.

Features

• Notch for the NexStar side bar so the shield sits flush
• Felt-lined interior for moisture absorption and stray-light control
• Quality ABS polymer construction
• Padded VELCRO® Brand closure won't scratch your tube
• Rolls up small for easy packing

Compatible telescopes

• Celestron NexStar 5 SE

Proudly made in the USA.

ASIAIR PRO is a smart WiFi device that allows you to control Mainstream DSLR cameras.

But some DSLR cameras have a 30-second exposure limit, which requires an external shutter release cable to ASIAIR PRO.

ZWO Shutter Release Cable is of the soft, curled type that can extend the usable length.

Raptors are popular and iconic birds, and are important ecologically, with some species listed as threatened. Yet they are among the most difficult birds to identify. This fully updated third edition of the popular and award-winning field guide Birds of Prey of Australia contains two sections: a field guide with distribution maps, detailed illustrations and information on identification; and a handbook which includes an overview of the current knowledge about raptors, including their biology, ecology and behaviour. An illustrated section on difficult-to-distinguish species pairs is also included, along with new photographs.

• Updated edition of this popular and award-winning field guide
• 'Bible' of raptor identification, providing current knowledge on the ecology and biology of these species
• New and improved photos
• Companion to the recently released Australian Birds of Prey in Flight, which aids identification of soaring raptors

Stephen Debus has studied or observed all 24 of Australia’s resident raptor species during the past 40 years, almost half of them intensively and some over many years. Awarded BirdLife Australia’s D.L. Serventy Medal for ornithological publication, his many works include the definitive field guide to this difficult group of birds.

ALP-T Dual Band 5nm Filter is best suited for optics f-ratios slower than f/3.6, the standard Antlia ALP-T Dual Band filter is highly recommended. Meanwhile, if you seek the best possible performance with any optics faster than f/2.2, the highspeed version is the best choice.

The Antlia ALP-T dual band 5nm series filter is a dual line-pass filter that was designed to be used primarily with one-shot color (OSC) cameras such as DSLR's and astronomical OSC cameras. It can also be used as a narrowband filter for monochrome cameras to save imaging time. The advanced multi-coatings on our ALP-T ultra dual-band filter effectively isolate the red Ha and the blue-green OIII lines light from emission nebulae, with almost total suppression of optical density (OD) 4.5 on unwanted wavelengths from light pollution, moonlight, and airglow. The result is that our ALP-T dual band 5nm filter creates a superior signal-to-noise ratio and better contrast in your images.

The Antlia ALP-T Dual Band filter enables the capture of the two main emission nebulae bands at the same time, whilst suppressing unwanted light pollution. It enables you to capture cleaner data and reduces the post-processing efforts to isolate faint details from the background light pollution.

Application and Performance:

Designed especially for optics, slower than f/3.6

Engineered specifically for use with DSLR, CMOS, and CCD color cameras

Suppression of optical density (OD) 4.5 on unwanted wavelengths adds signal-to-noise

Extremely steep bandpass edges minimize internal reflections

Ideal flat-top and moderate bandpass reducing spectrum downshifts

Ion Gun Assisted Deposition coating technology on the double-sided polished substrate making it the most consistent and accurate light pollution suppression filter

Designed to suppress artificial lighting from Bortle scale 1 to Bortle scale 8

Near IR (NIR) is blocked up to 1050nm

The Celestron Dew Heater Ring is the ideal dew prevention solution for your Celestron telescope. This must-have accessory will improve your observing or imaging nights year-round. The Dew Heater Ring permanently mounts to your 8" Celestron Schmidt-Cassegrain (manufactured 2006 or later), EdgeHD, and the 36cm RASA optical tube, replacing your retaining ring so you'll never be caught without it. The installation process is quick and easy (follow the manual for instructions).

How it works

The Dew Heater Ring replaces the retaining ring on your Schmidt corrector lens for efficient heating across the lens. The ring is constructed of lightweight, durable aluminum. Its rigid frame supports the cable circuity and the telescope's Schmidt corrector lens. Unlike other heating bands or strips that inefficiently heat the lens cell to warm the glass, the Celestron Dew Heater Ring heats the corrector glass directly, providing the most efficient transfer of heat to prevent dew formation.

Simply plug the ring into an external 12V DC power source for consistent, continuous heat that will prevent dew from forming even under heavy dew conditions. The Dew Heater Ring features two storage clips to keep the power and thermistor jacks secure when not in use while accommodating the telescope's dust cover.

The Dew Heater Ring also comes with a cable management clip that connects to the telescope's front cell. Corral the power and thermistor jack to prevent them from dangling and reduce unwanted pulls on the cable connection to the rings.

The Dew Heater Ring comes complete with:

• Dew Heater Ring
• Cable management clip
• Power jack extension cable
• Paper installation shield

Enhance your setup

To achieve the highest level of dew prevention while maximizing power efficiency, we strongly recommend pairing the Dew Heater Ring with a Smart DewHeater Controller (sold separately). The controller uses the ring's built-in thermistor and its internal environmental sensor to provide just the right amount of heat to the corrector to prevent dew based upon the ambient temperature, ambient humidity, and temperature of the Schmidt corrector, which can dramatically reduce the ring’s power draw, greatly increasing battery life. The ring also includes an extension cable for connecting the ring directly to one of the controllers’ heater output ports, or to a third-party controller’s heater output port. (Note: the ring’s integrated thermistor is only compatible with the Celestron Smart DewHeater Controllers).

We also recommend adding a dew shield to your setup. While not mandatory, a shield will cut down on the amount of power the Dew Heater Ring needs to keep the optics clear.

The Orion Illuminated Plossl 12.5 mm eyepiece is a vital addition to any astronomer's equipment collection thanks to its many useful applications.

Achieve precise alignment of computerized GoTo systems easily by using the relatively high-power 12.5 mm focal length eyepiece to accurately center alignment stars. The illuminated reticle enables you to precisely center alignment stars and objects in the telescope, thus increasing the accuracy of the GoTo system.

The 4-element Plossl design is also well suited for off-axis guiders, where light gathering is minimal, to help ensure tracking accuracy during guided astrophotography sessions. Use the 12.5 mm Illuminated Plossl with an off-axis guider (sold separately) to keep a guide star centered precisely to capture tack-sharp astrophotos.

A 4-element Plossl design with fully multi-coated lenses ensures bright views through the illuminated reticle eyepiece. Its 40° apparent field is ideal for multiple functions. The LED-illuminated double crossline reticle has adjustable focus and brightness. Three GP-189 batteries (included) are required for illuminator operation. Also compatible with three SR-54, SG-10, or equivalent button-cell batteries (not included). The Orion Illuminated Plossl 12.5 mm eyepiece features a 1.25" barrel diameter, compatible with 1.25" telescope focusers, or 2" focusers equipped with a step-down 1.25" adapter.
