The compact all-rounder from APM with two-lens FPL53 & lanthanum H-LAF53 optics

The new APM 140 f / 7 impresses with its high performance. We have now succeeded in developing this 2nd telescope with a high-quality optics and a solid tube at a previously impossible price. The new 140mm f / 980mm SD has a doublet optic with SD glass, one of which is made of FPL-53 for maximum performance. With the optional Riccardi reducer, you can achieve an effective focal length of 735mm and an aperture ratio of f / 5.25. This innovative combination leads to a color correction that is far above the usual in this price category. In order to guarantee the typical high quality of APM telescopes, every optic goes through an interferometric test at 532nm (green) before shipping.

The instrument is delivered with a massive 2.5-inch extension. The pull-out is particularly suitable for heavy accessories and offers an absolutely vinification-free image for large-format chips.

 

FEATURES

  • Very high-quality workmanship and convincingly good optical quality
  • Pure color optics with FLP53 glass
  • Precise 2.5 "extension 1:10 for heavy accessories
  • With f / 7 ideal for visual purposes
  • Can be expanded to an astrograph (f / 5.25)
  • CNC pipe clamps
  • Handle
  • Very good price/performance ratio

 

With a focal length of 980 mm, the 140mm SD-Apo is a real all-rounder. The observation of close double stars with high contrast up to detailed planetary observations will be a lot of fun with this device. In addition, this new apo is very light at only 9.8 kg and can be used on compact mounts.

The well-known APM quality has proven itself in all areas. The new 2.5 "focuser with rack and pinion drive and 1:10 reduction remains stable even under high loads and is therefore also suitable for photography. The attention to detail can also be found in the enclosed 2" to 1.25 "eyepiece adapter, which is a completely has a new design that clamps the eyepiece evenly and thus works much better than conventional adapters with a simple brass clamping ring and screw.

With the new 140mm SD-Apo, we offer you an apochromatic refractor of incomparable performance at an unbelievable price.

  • Optical tube
  • 1 pair of pipe clamps with handle
