Ursa Minor and Draco


Draco, Lyra, Ursa Minor

This (Fin@l) image is a composite of over 50photographs out of some 140photos of 30seconds exposure each, here they were taken continuously for over an hour.
The rotation of the earth makes the stars look like they are moving around the North South Axis of earth's rotation.
As a result the stars make small trails in each successive photograph (which if stacked will look like the last image Star Trails), to account for earth's rotation, each successive photo has to be moved a fixed amount Up-Down(Y) and Left-Right(X) and Also Rotate (R)

For Post-Processing, the RAW(CR2) files were "Registered and Stacked" i.e. each and every star is located (X,Y co-ordinates) with precise brightness and size(in pixels) and the best 80% photos were used make the Semi-Final Image as a 32Bit (High Dynamic Range HDR)Tiff file, note the 32bits part, so the image will look too darkly n flatish on regular LCD/CRT monitors, I used Photoshop to develope the 32bit HDR image as a high Contrast image, which I then "Level" and adjust the colour-Contrast (Curves)


This photograph is a stack of all the photographs about 140, as they came from the camera, or this is how the photograph will look if you take one photograph over 60mins facing the Northern Sky.

Deep Sky Objects

(PAS Catalog)

M-29

null

M-39

M-39 Through binoculars, this open cluster is very impressive. It is large and bright and stands out well from the background. I see it as having an overall triangular shape. Through a telescope, it loses some of its impact, because of its size and the fact that it is not very concentrated to the center.
This small open cluster is seen through binoculars as a diamond shaped grouping of about 6-8 stars in a nice field. In a telescope, the count increases to about 15 sparsely concentrated stars.
