I found motorbike covers from ebay come in different sizes and shapes and work a treat. Telegizmo is niche and overpriced BBQ covers IMHO. These days every accessory that has the word "astro" or "telescope" has an insane mark up. Another tip if you're looking for cylindrical bags to carry your tubes look no further than drum sets bags. They're good quality, heavy duty and great padded carry bags.
