DESCRIPTION

Astro-Physics 10 x 60 Vario Finder & Guider Bracket Kit

The Baader 10 x 60 Vario Finder System is unique in that it utilizes a high quality 2-element Zeiss designed objective and an interchangeable T-2 accessory system that will allow the included 45-degree prism to be switched with user-provided 90-degree prisms, or used in a straight-through configuration. Because of the exceptional quality of the optics, this finder will also be able to be used as a guide scope, employing a variety of new 3rd party guide cameras.

  • High quality 61 mm f/4 objective with a focal length of 250 mm
  • Coarse focusing is provided by the sliding draw tube (35 mm travel), and fine focusing is performed using the threaded objective cell with lens-locking ring (12 mm travel).
  • 1.25-inch brass clamp ring with 3 thumb screws for interchangeable eyepieces and accessories
  • 45-degree erecting prism with 1.25-inch nosepiece and T-2 thread
  • 25 mm eyepiece with variable brightness illuminated measuring reticle
  • Retractable dew shield
  • It is recommended that you use guide cameras with 7.4 micron pixels or smaller.

About the AP Vario Guider Bracket°

The Astro-Physics designed Guider Bracket greatly expands the versatility and functionality of the Baader 10 x 60 Vario- Finder Scope. By removing the finderscope's 45-degree prism and reticle eyepiece and substituting T-2 extension tubes, the finder transforms into a straight-through guidescope. This unique Guider Bracket provides the robust, flexure-free structure to hold even the heaviest guide cameras. Whether you use a feather-light camera, such as the SBIG ST-i, QHY5L-II and Starlight Xpress Superstar, or a heavy-weight, such as the SBIG ST-402, this Guider Bracket will help you master auto-guiding.

About the Quick Release Base:

An enlarged Quick-Release Base (QRBASEG) provides the rigid foundation on which the bracket rests. The male dovetail base-rail allows the bracket to be positioned for proper balance, while providing an attachment point for the stabilizing guide ring. The guide ring is the key to rigidly holding the focuser's draw tube and the guide camera flexure-free. As your Astro-Physics mount precisely tracks around the sky, the protective felt lining of your telescope’s rings can allow a minute amount of scope flexure, affecting the otherwise perfect star shapes. Because this entire guidescope configuration is attached directly to your telescope (rather than the scope’s rings), guiding will follow your scope’ movement, not that of the scope’s rings and mounting plates. This will ensure that you get the imaging results you seek.

 

Vario Finder and Guider Bracket Kit includes:

 

  • 10 x 60 Baader-Vario Finder, includes 45-degree erecting prism and 25 mm reticle eyepiece for use as a finder
  • 10 x 60 Quick Release Guider Bracket (S1060QRGB)
  • Base for Quick Release Guider Bracket (QRBASEG)
  • T-2 Extension Tubes 40 mm (BP25B) and 15 mm (BP25A)

Guiding with AP Vario Guider

The AP Vario Guider works exceptionally well. I use the guider with the Lodestar 2x , which together have a guiding resolution of about 6.9 arcsec/pixel to effectively guide a 1,000mm focal length refractor imaging with a cmarea that has 3.8um pixels at a resolution of .78 arcsec/pixel. That is a guiding/imaging ratio of about 8.8:1. A key aspect to success is minimizing differential flexure, which this bracket is designed to do. Part of the design is mounting location, which should be on the scope--not the rings as explained in the instructions. If you follow them carefully, your guiding will be solid.
