[QUOTE="Moab Man, post: 739428, member: 11881"] So irritated. Typed this big long bit to help you out and the forum dumped it... Grrrrr This is what I use. The iPolar is an upgrade to the basic system. It allows for accuracy that you can't get without it. iPolar is a camera that you use with your computer and a free program to align off Polaris. The drawback is that with the iPolar you always need a computer. If you don't have it, long lens photograph just doesn't work that well. I'm typically shooting at 300-500mm for 2 minute exposures. [URL]https://www.ioptron.com/product-p/3550a.htm[/URL] Upside, long exposure without the stars trailing and you can collect data for color that is lost at higher ISO's and shorter exposures. Downside, you need to have a computer with you. From bottom to top: M8 Lagoon Nebula, M20 Trifid Nebula, and M21 Open Star Cluster (up and left of Trifid). The image could have been a bit sharper, but I had pretty serious wind buffeting. [ATTACH type="full" width="30%"]342242._xfImport[/ATTACH] [/QUOTE]
