Telescopes and other imaging equipment must be handled with extreme care. Below are some of the hard cases I use in moving my telescope and its accessories, especially when travelling to remote observing sites.
The Celestron Travel Scope 70 is a small telescope designed for viewing distant land-based targets (such as birds and trees) and for casual astronomical observations. While many enthusiasts would purchase this telescope as a grab-and-go telescope, I intend to use it as a guide scope for my autoguider setup.

I have just finished making a couple of solar shades using a solar filter. If you do not have access to a solar filter, you may use instead what is called a no. 14 welder’s glass, available in most local hardware stores.
Here’s my recent version of a peltier-cooled Canon 450D for astro-imaging. It is housed in an aluminum case with custom-fabricated mount to accept standard Canon lenses and T-adapters. The camera’s stock filters, both the IR and the dust-cleaning filter, were replaced with a Baader UV-IR filter to optimize sensitivity to H-alpha wavelengths. During operation, sensor temperature drops to 35 degrees C below ambient.
During an exposure, the imaging sensor of a DSLR heats up to 10 degrees above normal exposure, resulting to noisy images. By cooling down the sensor, it is possible to eliminate or somehow minimize this thermal noise.
The Sky-Watcher Equinox 100 ED 4 in f/9 refractor serves as my main telescope both for visual observation and astrophotography. The telescope comes with aluminum-lined wooden carrying case. It is supplied with two eyepieces: 25 mm and 5 mm. Supplied also is a 90-degree 2-inch diagonal mirror and an 8 by 50 finder scope.
The Optical Tube Assembly (OTA) features a 4-in f/9 extra-low dispersion (ED) apochromatic (APO) lens design. It has a 2-inch/1-inch dual-speed Crayford focuser with a thumbscrew underneath for locking the draw tube once focus is achieved.
