Don't wait for Cyber Monday!

Don't wait for Cyber Monday!
Save $150 all month long on a Bresser 208mm Newtonian!
 

Bresser 208mm Newtonian's fast optics
& large aperture are ideal for deep sky imaging!
 
On sale for $349.99, this Bresser f/3.9 Rich-Field Newtonian has an 8.2-inch aperture that drinks in light to truly open up the night sky by showcasing stunning galaxies, tumultuous nebulae and brilliant clusters. Through its eyepiece, one can witness the legendary Orion Nebula resolve into a glowing cocoon teeming with billowing gas and newborn stars that are nestled in its wispy embrace. One can see the structures of galaxies like the spiraling arms of the Whirlpool Galaxy or the distinct bulging center and signature dark dust lane of the edge-on Sombrero Galaxy. Countless deep sky wonders like these are within easy reach of this Newtonian's generous aperture. The combination of that factor with fast optics and wide field views makes this telescope a great choice for those venturing into the field of astrophotography. As an added incentive for imagers, the signature cradle ring assembly has a built-in handle that can do double duty as a camera mount for piggyback astrophotography. Other features include a dual speed focuser and a no-tool collimation design that makes precision adjustments of the primary and secondary mirrors easy.
Looking for big aperture with less weight?
 
Explore Scientific has another excellent option for deep sky enthusiasts that offers the same excellent performance as the Bresser 208mm Newtonian with considerably less weight. This 208mm Newtonian has a carbon fiber optical tube that dramatically reduces the weight of the instrument without sacrificing critical aperture. The lighter weight of the carbon fiber material puts less burden on the mount, which in turn enhances accuracy and overall performance. The carbon fiber housing also virtually eliminates focus drift during long exposures.  
This stunning image of the Elephant Trunk Nebula (IC 1396) was captured by Christopher Sullivan using the Explore Scientific Carbon Fiber 208mm Newtonian. For additional technical information, visit Christopher Sullivan's gallery on AstroBin
Get stellar images with the HR Coma Corrector!
 
Coma is a common optical aberration that can plague the outskirts of an image that may have taken hours to capture. When coma is present, stars in the center of the field will pop like precise points of light, but stars at the edge take on an unnatural comet-like shape. Explore Scientific's HR Variable Coma Corrector will help you minimize or even eliminate image aberrations caused by this off-axis optical phenomenon even in fast Newtonians. Created by world famous optical designer Harrie Rutten, our 2" coma corrector offers multi-coated lenses, a black-anodized aluminum barrel with spacer markings and a textured rubber grip.
