Small and cheap telescopes aren't something providing much value. There are small achromatic refractors that have their own problems with chromatic aberration and cheap plastic finish. But what about a 60mm Maksutov telescope? Lets take a loot at Omegon MightyMak 60.
RedCat 51 is a lightweight and portable telescope-lens from William Optics. With 250 mm of focal length at f/4.9 it can be used for widefield deeps space imaging or during daytime as a tele-photo lens. I've paired it up with ToupTek ATR3-16000-KPA - a cooled camera with large color sensor. Here is my initial take on the setup.
Takahashi Collimation Telescope can be used to collimate RC, DK, SCT and other Cassegrain telescopes using nothing but some light. Let see how it all works out.

I've decided to check it out and ordered few more recent books about astrophotography. Here is a short review of them.
