First, the finderscope should already have been aligned to the telescope by centring a distant fixed object in the telescope's field and then adjusting the finderscope with its adjusting screws until the object is at the centre of the crosshairs. This Sky-Watcher 8" Quattro imaging Newtonian is ultra-fast and incredibly simple to use. For visual use, only a rudimentary alignment of the polar axis of your equatorial mount is required. Other than wei… Moving up from my Skywatcher 150P (150/750) what would be a big improvement from this scope? Skywatcher Quattro 10S Friday, 8 November 2013 | Andrew I bought this mainly because my NEQ6 was struggling with 12" Newt plus guider set-up, an EQ8 is just way … Skywatcher Quattro F4 can it be used for observing aswell as imaging? Specifications: Optical Design:Newtonian Reflector; Aperture (mm): 203 mm (8 in) This 8” SkyWatcher Quattro Imaging Newtonian has … Even better performance for astro-photography, and visual use, can be achieved when used in combination with the Sky-Watcher Quattro coma corrector. My 2¢, Additionally, the tube length has been slightly shortened to optimize performance for wide-field prime-focus photography. This fast 8-inch f/4 Newtonian telescope has a superb mirror set, allowing you to see sharp, high contrast images of celestial objects. Skywatcher 200P-DS or Skywatcher Quattro 8-S I would like the 8-CF, but cannot see anyone selling the carbon tube in the UK. Visual and imaging. The SkyWatcher Quattro 8 is a fast f/4 Newtonian with extra features that make it an excellent OTA for imaging as well as wide field visual observations with the addition of its dedicated coma corrector (sold separately). After much deliberation and conversations back and forth with Bernard at Modern Astronomy, I finally decided to go for the Skywatcher Quattro 8-CF 8” F4 Reflector, there was a number of factors that helped me reach this decision, most of it was the British weather being so unpredictable that I needed to get as many photons for my images in the shortest available time. It's what is centered is my target that I'm looking to observe. Additionally, the tube length has been slightly shortened to optimize performance for prime-focus photography. Ideally, I would prefer a 300, then I could dispense with my wheeled Skywatcher 300p goto Dob, giving me more room in my Skyshed Pod. I find my 200mm F/4 Nextonian works great for visual use. Even better field edge performance for astrophotography, and visual use, can be achieved by adding the Sky-Watcher Quattro coma corrector. The Sky-Watcher Quattro 8" (205 mm) Imaging Newtonian OTA is a great optical tube assembly for either visual astronomy or astro-imaging work. Maybe a bit of seagulls at the edge of field- but that doesn't bother my eyes.
