A common type of reflector is the Newtonian telescope which was invented by a figure known to all, Sir Isaac Newton. The amateur who has had an introduction to astronomy via a refractor telescope will find that an “upgrade” to the reflector will allow greater exploration of the night sky....
Another option, is a 50mm finder scope that will let you use a separate eye piece. I use an Astro-Tech 50mm (Long Perng). The views through it are very nice and you can't beat the weight/size. Third photo shows the larger Neweer ball head mount - I needed something with larger ...
For example a 250mm Newtonian reflector, a 250mm Schmidt Cassegrain, or (for planets) a 120mm refractor (i.e: 1, 2). The prices are referring to the cheapest options of the specified apertures. By "large" I'm refering to telescopes up to 12" aperture (obviously there are larger ...
- Skywatcher ED120. The Vixen above got me hooked on ED doublet views so I wanted more of that. The ED120 was another purchase from another SGL member probably around 8 years ago now. It is one of the original gold / cream colour scheme ones. It came with a William Optics crayf...
The C925 is a good telescope, and size matters. If you aren't looking for a larger field of view or the sun (where seeing often, but not always, makes large magnifications useless), you probably don't need an additional refractor. ...

If the residual color in a Schmidt-Cass is on the level of a good ED triplet refractor, I would say it is not an issue for most SCT users. I have never noticed any in my old Celestron 8 alongside a Newtonian reflector. The nearly flat corrector gives only a tiny amount of refraction...
