An extremely deep M45 image taken with the Sky 90s and M26C OSC CCDs. Over 25-hours total imaging time using 10, 20, and 30-minute sub-exposures. The image “cleaned-up” beautifully with Noel Carboni’s AstroFlat plugin.

Zoom-In – Single frame original Hyperstar on a C11 with an H9C OSC CCD.

Zoom-Out – Single frame Sky 90 with an M25C OSC CCD.

Here’s a 3D printed Digital Sundial – set up and working for real in the garden.

Compass to point North and protractor to set latitude.

All works!!

A nice region of blue in a sea of red – reflection nebula NGC6914 in Cygnus.

Zoom-In – single frame original Hyperstar on a C11 with an H9C OSC CCD.

Zoom-Out – single frame, Sky 90 array with M26C OSC CCDs.

Zoo-In – Original Hyperstar on a C11 with an H9C OSC CCD.

Zoom-Out – Sky 90 with an M25C OSC CCD.

Both are single frames.

Zoom In – Original Hyperstar on C11 with H9C OSC CCD.

Zoom Out – Sky 90 single frame with M26C OSC CCD.

Got today’s EPOD with the image of M11 sitting in the Scutum star cloud 🙂 

Thank you Jim at EPOD for continuing to publish my work.

One way of taking a high resolution zoom-in zoom-out of a deep-space image is to take the region concerned at 2 different focal lengths, or to take a single frame and then a mosaic of frames of the region. This image showing the Running Man and the whole of the central part of the Orion nebula uses a combination of both techniques. The Running Man alone is a Hyperstar image taken at 550mm focal length, and the central Orion nebula image is a Sky 90 4-frame mosaic taken at a focal length of 450mm. Enjoy 🙂
