| Notes |
This image was inspired by Scott Rosen. He showed me an image he took once of M81 that was truly outstanding. He mentioned the image contained roughly 8 hours worth of 45 second subexposures!! I thought that would be a good way to sell the fact that you really do not have to break the bank to have a good image. So long as you have a mount that will hold a 45 second subexposure (most goto mounts on the market will easily do this with a proper alignment), you are really not looking at a ton of money involved here. I hear folks tell me all the time. "It just costs so much to get into imaging!" I completely disagree. With a small bit of patience, an image such as this can be had for a very reasonable amount of money spent. I only used a Takahashi mount because that's what happened to be available at the time. |
