Make your focusing for astrophotography an easy and magic task .

About Bahtinov mask
The Bahtinov mask is a device used to focus small astronomical telescopes accurately. It was invented by Russian amateur astrophotographer Pavel Bahtinov in 2008. Accurate focusing of telescopes and astrographs is particularly of concern to those involved in astrophotography. The telescope is pointed at a bright star, and a mask is placed in front of the telescope's objective (e.g. primary mirror).

How does it work?
Set up your telescope and imaging equipment as normal. Then simply locate a bright star (maybe Spica?) with your telescope, attach the Bahtinov mask to your telescope and watch the diffraction spike pattern around the star as you adjust the focus. When the middle diffraction spike is centered in the outer spikes, you're in focus. Very little focusing travel is required to move the inner diffraction spike, which means the focus is extremely accurate.

Program type>
Suitable for telescopes Dew Shield or Front Outer Diameter Front From 115-165mm (4.5in-6.5in) - For 127mm Celestron or Skywatcher Maksutovs, Meade 127 ED APO, Celestron 5 SE Etc.

Features

  • Bahtinov masks make focusing for astrophotography an easy task. Watch the two slanted areas create an "X" over the star. The vertical slits create a moving bar that is centered on the X when you are at focus.
  • Suitable for telescopes Dew Shield or Front Outer Diameter Front end Diameter From 115-165mm (4.5in-6.5in) - For 127mm Celestron or Skywatcher Maksutovs, Meade 127 ED APO, Celestron 5 SE Etc.
  • The mask attaches securely to your scope using brass screws with soft transparent nylon cover to ensure the finish of your telescope is protected.
  • Light weight so you wont upset the balance on your scope.
  • It will take less time to achieve perfect focus with your new mask which mean you spend more time imaging photons rather than focusing them

A dew shield is an essential accessory that protects your optical tube from excess moisture forming condensation on the corrector lens. A lens shade also helps block out stray light outside the path of the telescope for better viewing and astroimaging.Astromania dew shield keeps dew away and gives you clear observing for the entire night and protect your optics from dew and stray light.In clear nights, dew is often a real problem. After only a few hours, the optics start fogging, making observations or photography impossible. A good dew shield reduces the risk of fogging and extends the observing time. On the inside, dew shields from Astromania Optics are coated with felt which absorbs dew. Dew can be a problem at almost any time of the year. Especially when it's a little cooler, tiny droplets condense out from the water vapour in the air and fog-up the optics of your telescope. The Astromania dew shield keeps dew away and gives you clear observing for the entire night. Details: Suitable for tubes: diameter from 203 mm to 221 mm Material: ABS Contact surface to the telescope: foam rubber Inner liner: black felt - light and dew absorbing Height of the dew shield: 320mm Total lenght: 750mm

Features

  • Astromania flexible dew shield are constructed of black ABS plastic and are all felt lined for maximum absorbtion of moisture and baffling of stray light. Particularly strong attachment to the telescope by non-slip foam rubber at the contact area to the tube.
  • The flexible design is quite practical, as it allows you to slide the dew shield behind a cupboard or next to your eyepiece case - it is optimally space-saving!
  • The dew shield is lined on the inside with a black velvet-like fabric. This not only minimizes reflections but also ensures that no dew can reach the telescope's optics.
  • Height of the dew shield: 320mm, total lenght: 750mm. Suitable for Telescope tubes from 203mm diameter to 221 mm diameter.A dew shield prevents your telescope optics fogging-up in the first place. It keeps the optics completely dew-free and lets you observe for hours with the optimal view.

SVBONY Dew Heater Strip DN40cm 5V for Telescopes and Camera DSLR Lens Linear Temperature Control Devices Keep Them from Fog Dew Freezing

 PartNumber: W2592   |   Asin: B07R3RM3KG

Dew heater bands are used to prevent condensation on optical surfaces in cooler weather.
The most common source of moisture is dew, however; moisture from your own eye can also condense on an eyepiece in extremely cold weather.
When is comes to dew, the best defense is a good offense. Simply maintaining the temperature of your optical surfaces above the dew point will prevent condensation from happening.
The most problematic optical surfaces, listed in order of their susceptibility are as follows:
1) Corrector Plates on Schmidt-Cassegrain Telescopes,
2) Meniscus lenses on Maksutov Cassegrain Telescopes,
3) Objective lenses on Refractors,
4) Eyepiece eye lenses in very cold weather. Thousand heater bands are wrapped around the outside of the area to be heated, such as around the metal cell of a corrector plate or objective lens.
They attach themselves using a built in Velcro elastic strip. In the case of an eyepiece, the band wraps around the eyepiece itself. Specification:
Cloth covered with foam insulation on outer side for maximum efficiency and performance
Electrical interface: USB Power Bank is required for 2A
Voltage: 5V
maximum power: Package Includes:
1 x DN40cm Dew Heater Strip

Features

  • Super fast and continuous warming with fast start up of 5 seconds to heat

A dew shield is an essential accessory that protects your optical tube from excess moisture forming condensation on the corrector lens. A lens shade also helps block out stray light outside the path of the telescope for better viewing and astroimaging.Astromania dew shield keeps dew away and gives you clear observing for the entire night and protect your optics from dew and stray light.In clear nights, dew is often a real problem. After only a few hours, the optics start fogging, making observations or photography impossible. A good dew shield reduces the risk of fogging and extends the observing time. On the inside, dew shields from Astromania Optics are coated with felt which absorbs dew. Dew can be a problem at almost any time of the year. Especially when it's a little cooler, tiny droplets condense out from the water vapour in the air and fog-up the optics of your telescope. The Astromania dew shield keeps dew away and gives you clear observing for the entire night. Details: Suitable for tubes: diameter from 148 mm to 167 mm Material: ABS Contact surface to the telescope: foam rubber Inner liner: black felt - light and dew absorbing Height of the dew shield: 200mm Total lenght: 580mm

Orion 15098 Light Shroud for SkyQuest XX14 Truss Tube Dobsonian

Model: 15098   |    Mpn: 15098   |    Ean: 0759270150983   |    PartNumber: 15098   |   Asin: B002QV86HK

For the best performance from any truss Dobsonian telescope, a light shroud is a must. This one, custom designed for the SkyQuest XX14, is made of a stretchy nylon blend material that fits like a glove over the truss poles of the XX14, fastening with thick elastic bands on both ends. The water-resistant, opaque black fabric blocks stray light from entering the optical path, thus improving image contrast. It's also breathable, which minimizes unwanted vibration of the scope in breezy conditions. Use of the shroud will lessen the accumulation of dust and dirt on the mirrors during use, and will help prevent dew from forming on them. Made in the U.S.A. WARNING! When using a truss tube Dobsonian for solar observing, always use a Light Shroud and a properly sized solar filter. Make sure there are no gaps between the Shroud and the telescope where direct sunlight can reach the mirror, otherwise eye injury or damage to the telescope can occur. Before using any telescope for solar observing, install protective covers on all optical components. Glancing through an uncovered optical system can cause permanent eye damage. Always install protective caps on all optical instruments if left out during daylight hours.

Features

  • Custom-designed light shroud for the SkyQuest XX14 Truss Tube Dobsonian reflector blocks stray peripheral light to improve view contrast
  • The Light Shroud is made of opaque black, stretch nylon that fits like a glove and stays put on the truss tube reflector with elastic on both ends
  • Breathable fabric lets air pass through and doesn't sail in light breezes
  • Lessens accumulation of dust and dew on mirror surfaces while optimizing view contrast during use
  • Made in the U.S.A.
