You may have come across the term “aperture fever”. Its when you have a telescope and want or desire a larger aperture instrument. So for example you may have a 4″ or 5″ aperture scope and would like to upgrade to say an 8″ or much bigger so you can see or image fainter objects and see more detail too.
How about aperture fever in the form of a 14″/355mm aperture scope…..Celestron’s largest aperture offering in their SCT and EdgeHD line-up.
These OTA’s (Optical Tube Assemblies) have a focal ratio of F/11 giving a focal length of (a massive) 3910mm (154″) – ideal for planetary viewing or imaging – and have light gathering nearly 2600x that of the human eye! The telescopes feature Celestron’s StarBright XLT coatings and are Fastar/Hyperstar ready for fast widefield imaging. The OTA’s weigh ~21kg so you will need a suitable heavy duty mount capable of carrying this heavy payload. Don’t forget you need to add a few extra Kgs too to this figure if you are imaging. Both of these OTA’s are in stock.
For many an 11″ SCT is a perfect large aperture upgrade as its manageable in terms of its weight, at just over 12kg and size (24″ length). Furthermore there are a number of mounts “out there” that can carry its weight plus accessories (e.g. camera etc). The 11″ OTA has ~1600x light gathering compared to the eye, has a focal length of 2800mm (F/10) making it ideal for Lunar/planetary viewing or imaging, comes with Celestron’s StarBright XLT coatings for the best light transmission and is also Hyperstar/Fastar ready for wide field fast F/2 imaging.
We have these in stock with the CG-5/Vixen style dovetail which can be changed to a wider CGE/Losmandy type if needed for e.g. astrophotography.
