The idea was Project Patchwork - A massive mosaic of the sky covering the area from Orion to Andromeda. Many people took part in the project and contributed some great images. Of course, the name "Patchwork" implies that these are all images processed separately by those who contributed their images, with varying levels of color balance and backgrounds.

For beginners, this can be a real pain in the butt, but we are here to help you go through that process! You will need some basic tools in order to do this. You will need a collimation cap (usually come with newtonians), a screwdriver, and (sometimes) a certain sized hex key. A laser collimator, if aligned properly, can really help too, but it is not mandatory. I..." Tag: Visual edit

When the most reasonable exposure times you can achieve with a low focal length lens total in the 10's of seconds, you wont catch a lot of light. With a star tracker, you can expose for much longer. "Tracking" simply means your camera will "follow" the stars. In reality, it is actually cancelling out the Earths rotation. For starters, you will obviously need some form of tracker. If you are..."

When doing astrophotography, there are essentially two types of light being captures, infrared (IR), and visible (Vis).

To get some acryonyms out of the way here is a brief definition on some cameras: * '''Digital Single Lens Reflex (DSLR)''' refers to a common consumer camera form factor which involves a small mirror that flips up to direct light to the view finder for framing. i.e. Canon 60D.

Put very simply, polar alignment is aligning the right ascension axis of our telescope mount with the rotational axis of the earth. Unguided telescopes track on a single axis (the R/A). This works by moving the telescope at a constant sidereal rate to counteract the way the earth is moving. The mount doesn't know that it's not aligned, it will move at the sidereal rate r..." current Tag: Visual edit

When you look up at the sky from the middle of NYC you may only see a few of the brightest stars. Drive a few hours away and you will see thousands. While light pollution won’t make or break your chances at a successful image, it sure can make getting there a pain. ---- ==== Measuring light pollution ==== ----Light pollution is quantified by a special system called the Bortl..." current Tag: Visual edit

Generally speaking the noise follows fairly predictable patterns and can be removed by the use of calibration frames. This results in a smoother image - a well calibrated image is far easier to process than just a stack of light frames. Generally speaking the more frames you use, the better your image will be. This effect does drop off however, the noise reduction depends on the square ro..." Tag: Visual edit

As planets are so bright and affected by atmosphere the best way to do this is by trying to get as many frames of them as possible with a high FPS video. This overcomes the effects of atmospheric turbulence and allows us to stack many good quality frames. Solar system imaging is a good way to get into astrophotogra..." current Tag: Visual edit

Its not. There are however, dangerous things you can do ''while'' observing. A telescope is a light amplifying device.
