The latest version of the Starwave 70 EDQ-R refractor has a four-lens system to give a flat field image circle of approximately 42mm at 350mm focal length, with a focal ratio of F5). The focuser is CNC machined and the telescope has a Camera angle adjuster, Rotator and Tilt facility.
Premium Japanese ED S-FPL53 glass is used for excellent colour correction. Super-high transmission coating (STM Coating) is used on all air-to-glass surfaces to ensure high contrast.
The telescope tube is made from light weight aluminium alloy with CNC machined components. A tough matte pearl powder coated tube and hard-anodised fittings give durability and great looks.
The Starwave 70 EDQ-R Quad APO is intended for astro photography and the focuser terminates in an M48 Male threaded rotator plate with locking thumbscrew. All screws are teflon tipped and grip on a flange for accuracy. The rotator plate includes a "push-pull" tilt adjustment system to enable you to square up the image sensor to the focal plane.
No extra flatteners are required and the camera sensor is automatically at optimum spacing when focused on infinity.
The backfocus from flange to sensor is 66.78mm with the tilt adjuster at zero tilt. The focuser is a good quality rack and pinion unit which has been modified to improve rigidity.
Altair Hypercam cameras are en excellent match, especially the Hypercam 183 Series 20mpx cameras. Simply attach the camera with an T2-Thread Female to M48 Female adapter, or even screw the 2" nosepiece directly to the M48 male thread on the back of the focuser (the nosepiece has an M48 female filter thread nn the front).
You can attach a DSLR by means of the Altair M48 Canon or Nikon DSLR adapters. (Ensure the inner ring grub screws on any M48 DSLR adapter are tight to reduce the chance of tilt).
For DSLR use, a clip filter is recommended to control light pollution.
The rack and pinion focuser is compatible with Pegasus motor focusers enabling full autofocus control using various programs, including SharpCap.
For dew control, and to reduce the chance of the outer metal tube losing heat faster than the lens elements and constricting the unevenly, or internal condensation forming in the air gaps between lenses, we recommend the high power Dewzapper "DSLR" heater, product code DEWH-34-DSLR is used. In winter time the dew heater is best left on running at the upper temperature range to keep the whole OTA warm.
For autoguiding and super accurate polar aligment (with Sharpcap's polar align feature), you simply can't beat the Altair Astro 60mm Guide-Scope, or the Altair Starwave 50mm Guide-Scope, and any of the Altair GPCAM camera range. The best configuration would be a side-by-side using the Starwave 110mm Guide scope rings and 200mm Vixen-format Dovetail bar (code: SWGSR-110-200) and dual Vixen dovetail bar kits. (Code: SW-DUAL-VBAR-230MM)
