- Adequately capable telescope for a non astronomer, based on a price point purchase.
I am investigating the Equatorial Mount system after setting up the scope for the local latitude. So far I have viewed the Moon, Mars and Jupiter, but have yet to investigate further horizons. The large aperture certainly gives bright impressions of objects and I have found the magnification to be more than adequate. The only problems I have had are:
1. Stability of the image, especially whilst adjusting the Azimuth and Declination controls or the focus. This may require substantial tightening of the lock nuts and a slow, steady hand on focus. When stable, the images of the moon's surface are decent. I am still learning how to to use the telescope and may improve operation with further use.
2. The focus control seems to require extra fine adjustment to get the image to be in focus. Changing lenses requires the focus to again be adjusted, by which time the viewed object has moved.
3. Getting the attached LED sight aligned to the telescope, which required about five minutes work whilst sighting the moon. I may end up using a filling of Play Doh to set the sight rigidly.
I am surprised at the speed objects get out sight due to earth rotation, especially when changing lenses. Perhaps this is a call for later purchase of a motor drive. The free software that came with the scope is Stellarium and only for Windows and Mac operating systems. I use a Linux operating system, however Stellarium is a download/install available from the Ubuntu software repository. It was installed prior to any telescope purchase and is a very useful program.
