It's that time of year and if you are considering building an observatory and need some ideas, this 41 page booklet of reprints from Telescope Making Magazine has plenty of them (with lots of pictures). Examples include a simple light shield, domes, roll offs and garden shed conversion observatories. Printed in 1981, it is still a good resource for those considering building an observatory. The booklet is in very good condition.
