It is the open cluster M46. The Planetary Nebula (NGC 2438) is also visible!

Have a nice day.

Hi,

great image, weixing! great tracking as well. is this processed or raw?

It is after stacking of 3 images (114s + 64s + 30s @ ISO800) and heavily processed using Photoshop.

is this a true colour image? puzzled by the good balanced mixture of white and blue stars.

It should not be true colours... it is the colours my Canon 300D take. I think you can only take true colour by taking 3 separate monochrome exposures through red, green and blue filters and combine them together. Also, the RAW image got a milky layer on it... I think cause by light pollution. I remove it after heavily processing using Photoshop, but it cause the orange stars look whiter

any chance of blowing up the planetary. looks great in this picture....

It actually quite big in the actual size image... it just a small blue round patch anyway:

It is actually a very good scope... better quality than I thought, but I always taking others people car and the scope take up a lots of space in their car :oops: , so still thinking of selling it away and get a smaller physical size scope that won't take up so much space.

Have a nice day.
