This is a collection of bits and pieces to help me when I forget stuff.

My telescope
. Sky-Watcher EVOSTAR DS-PRO Series ED Apochromatic refractor. 80mm objective; 600mm focal length. It feature a doublet objective lens. One element is made from Extra-Low Dispersion (ED) glass, which virtually eliminates chromatic aberration. Top quality Schott glass is utilized for the Crown element. It has 9x50 viewfinder.

The mount is a Sky-Watcher EQ5 Deluxe Heavy-Duty Equatorial Mount.
For convenience there is a Sky-Watcher 90 Degree Polar Scope Eyepiece which is used for accurate alignmnent with the pole star and can also be used with the viewfinder for more comfortable looking at overhead objects. NB Only one counterweight is needed.

Motor drives. Sky-Watcher Dual-Axis Motor Drive for EQ5. Provides multi-speed (1x/2x/8x) motor tracking of the R.A. & DEC. axes. Battery-powered. 

Eyepieces and magnification.
Magnification is the telescope focal length (600mm) divided by the focal length of the eyepiece. The maximum useful magnification is  2 x objective diameter (80 mm)that is 160x. [So no point in using Barlow 2x magnification[

40mm. 15x. Not top quality but excellent for finding objects. Same magnification as my  Canon binoculars.
24.5 mm Meade super wide angle multicoated. 25x
12 mm Celestron X-CEL LX series.  50x.
5 mm   Celestron X-CEL LX. series 120x.
                Note:  these eyepieces give 60º apparent field of view.  The premium six-element optical set is finished with multiple layers of high-transmission coatings for clear, sharp images.   The edges of the optics are blackened for increased contrast.  16 mm of comfortable eye relief – advised as very beneficial for spectacle wearers.

  My 'astronomy' binoculars. Canon 15x50 with optical stabilisation. These are magnificent, holding everything completely steady at this high magnification. See Review
