How to collimate Celestron Skymaster 15×70 binoculars

The video below applies to the Celestron Skymaster 15×70, 25×70, 20×80 binoculars plus the Cometron 12×70. Collimation is a very simple process with no dismantling needed. The adjustment screw is located under the rubber covering on the hand grips. I like to work on one side only. Only adjust the opposite side for minor adjustments if needed.

Place the binoculars on a solid base or tripod to do this. Invite a friend to help if you struggle to make the adjustment while looking through them at the same time. See the video below for more details.

Skywatcher Panorama 23mm eyepiece video review

At 800g the 2 inch Skywatcher Panorama 23mm eyepiece is not as heavy as some 2″ eyepieces, but will require a sturdy mount and a focuser capable of taking the weight. 23mm is a good all round focal length for general use.

The eye cup is twist type. Unlike some twist eye cup eyepieces you do do twist the cup. Instead you twist the centre of the eyepiece body. Optics are Fully multi-coated with 7 lens elements. Threaded to accept 2″ filters

Ostara 20mm SWA70 eyepiece overview and review

Looking through astronomy forums, this eyepiece gets some mixed opinions to say the least. I may be wrong, but I would guess many of the views are from people that have not looked through this model.

For those who have looked through it, they have been impressed with the wide field of view, which far exceeds a standard plossl. Colours , contrast and edge of field quality far outperform plossls in the £20-£30 range.

One of our customers at Northern Optics was so impressed, they bought a second to use with their bino-viewer. Specs are 70 degree apparent field, fully multi-coated optics, solid build and internal blackened edges.

Fotomate VT-5006 tripod. Ideal for a Celestron C90 Mak

A customer came to our Northern Optics weekend outlet at the Waters` Edge country park and visitor centre looking to buy a tripod suitable for his Celestron C90 Mak spotting scope / telescope. It needed to be capable of holding it steady so he could look at the Planets. The mount he was happy with was the Fotomate VT-5006. With a payload capacity of 5kg, it was more than capable of taking the weight of the C90. The mount is easy to use and has a very smooth pan and tilt head with adjustable handle. Spare quick release plates are available.
