0.85x Focal Reducer/Corrector for Sky-Watcher PRO 80 ED APO is designed for serious Astro-Imagers. Optimized for the Sky-Watcher PRO 80 ED APO, this superb quality accessory effectively reduces the telescope’s focal length by a factor of 0.85x and provides much improved field-edge correction. Features:

• 55mm back focus
• M48 threads (not standard T-thread)
• Drops ProED 80 from f/7.5 to f/6.3

• A nice beginner’s set of 1.25” planetary filters for any telescope.
• See features on the Moon & planets in a whole new light.
• The aluminum cell is threaded on top and bottom for stacking.
• Includes Wratten #12 Deep Yellow, #21 Orange, #80A Light Blue, and a #ND-96-0.3 Neutral Density Filter with 50% transmission.

• A customizable way to reduce brightness and glare on the brightest celestial objects like the Moon, Venus, and bright double stars
• Adjust the level of light transmission from 1-40% for the best possible view for your specific target and current viewing conditions
• Simple to use—just rotate filter’s lower ring to adjust brightness 
• Threads onto any Celestron 1.25” eyepiece

Handy Camera Rotator for Sky-Watcher 72ED

• The 2" OIII narrowband filter isolates the two doubly-ionized oxygen lines (496 and 501 nm lines)
• Filter has ultra-hard, vacuum-deposited coating
• Eliminates un-natural colored halos surrounding bright stars

The L-Pro CCD filter improves the contrast of deep-sky objects and reduces the sky background.

• blocks UV and IR (700 - 1100 nm)
• high transmission at passband
• improved color balance for DSLRs and One-Shot Color Astro Cameras, e.g. ASI Color Cameras cooled or uncooled by ZWO.
• high optical quality
• in 2" filter cell
• The L-Pro Nebula filter permits roughly 3x longer exposure times than without a filter and therefore improves contrast significantly.

The L-Pro Astrophotography CCD filter is a filter for improving the contrast of deep-sky objects and dampening the sky background.

L-eNhance 1.25 "Optolong filter (M28x0.75) 31.8mm - Recommended for: shooting in double pass band (H-Alpha, OIII and H-Beta) with CMOS or CCD color cameras or DSLR

L-eNhance 2" Optolong filter (M28x0.75) 50.8mm - Recommended for: shooting in double pass band (H-Alpha, OIII and H-Beta) with CMOS or CCD color cameras or DSLR

Extra Narrowband OIII-CCD 6.5nm filter is designed for nebula observation allowing 6.5nm bandwidth of light centered on a wavelength of 500nm through, which corresponds to OIII emission lines, and reducing the transmission of certain wavelengths of light, specifically those produced by artificial light including mercury vapor, and both high and low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e. skyglow).

Extra narrowband SII-CCD 6.5nm filter (Sulful II for CCD) is designed for nebula observation allowing 6.5nm bandwidth of light centered on a wavelength of 672nm through, and reducing the transmission of certain wavelengths of light, specifically those produced by artificial light including mercury vapor, and both high and low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e. skyglow).
