Gosky Bahtinov Focusing Mask for for Telescopes Dew Shield or Front End Diameter from 115-165mm (4.5in-6.5in) -for 127mm Celestron or Skywatcher Maksutovs,celestron 5 Se,meade127 Ed Apo,etc

Model: QHAI0310   |    Mpn: QHAI0310   |    Ean: 0711102625977   |    PartNumber: QHAI0310   |   Asin: B07F7P53NJ

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.

3 X Brass bolt

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

Orion 15206 Cloak Cover for Large Mounted Telescopes

Model: 15206   |    Mpn: 15206   |    Ean: 0759270152062   |    PartNumber: 15206   |   Asin: B0069VZWKM

The Orion Scope Cloak Telescope Cover is an affordable and easy to use telescope cover that protects your equipment from dust, dirt, dew, and sunlight. Large aperture equatorial and altazimuth-mounted telescopes can easily be kept clean and tidy with this Scope Cloak. Mounted reflectors up to 10" (254mm) in aperture and refractors up to 120mm (4.7") in aperture and up to f/8.3 focal ratio can be conveniently sheltered from the elements. Keep your telescope set-up and ready for viewing in your garage, shed, or home observatory without worrying about dust and dirt contamination. Orion's Scope Cloak is made of a high-tech tear-resistant and water-resistant material that keeps your optics free of dew. The highly reflective exterior surface rejects solar radiation, keeping your telescope cool when left in sunlight and reduces cool-down time (the amount of time required for your telescope to reach thermal equilibrium after nightfall). The Scope Cloak Telescope Cover prevents dust form contaminating telescope optical surfaces, reducing the need to perform delicate and tedious cleaning procedures. A handy locking drawstring provides a snug fit once installed on your telescope. The Orion Scope Cloak Telescope Cover for Large Mounted Telescopes is designed for temporary outdoor use and is not intended to be used for permanent unsheltered outdoor storage. A handy nylon carrying pouch is included.

Features

  • Keep your telescope assembled and ready for action in your shed, garage, or home observatory with a ScopeCloak to prevent dust and dirt buildup
  • Protect an assembled telescope in the field before, between, and after observing sessions
  • Reflective Scope Cloak helps to avoid internal telescope heat build-up caused by exposure to sunlight

Orion 15101 Light Shroud for SkyQuest XX16 Truss Tube Dobsonian

Model: 15101   |    Mpn: 15101   |    Ean: 0759270151010   |    PartNumber: 15101   |   Asin: B0093V7M6M

For the best performance from our 16" XX16 Truss Tube Dobsonian, this custom designed Light Shroud for the SkyQuest XX16 is a must. It's made of a stretchy nylon blend material that fits like a glove over the truss poles of the XX16, 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 XX16Truss Tube Dobsonian telescope blocks stray light to improve image contrast
  • Made of opaque black, stretch nylon that fits the 16 Truss Tube reflector like a glove and fastens with elastic on both ends
  • Breathable fabric will stay-put in light breezes

Astromania Flexible Dew Shield for Telescope Front Outer Diameter from 100-123mm diameter - keep dew away and gives you clear observing for the entire night

Model: SKU_AM_FDS435   |    Mpn: SKU_AM_FDS435   |    Ean: 6970019295671   |    PartNumber: SKU_AM_FDS435   |   Asin: B01M0OGKUD

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 100 mm to 123 mm Material: ABS Contact surface to the telescope: foam rubber Inner liner: black felt - light and dew absorbing Height of the dew shield: 180mm Total lenght: 435mm

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: 180mm, total lenght: 435mm. Suitable for Telescope tubes from 100mm diameter to 123 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.
  • Flexible Velcro fastener provides optimal adaption to the diameter of the telescope or telephoto lens. Ideal for the transport - the dew shield can be placed space-saving around the tube.Very important if you live in a place that has dew often or if you use your scope in the daytime and want to keep stray light out and the contrast high.
