Deepsky wonders via my ETX-70

These deepsky galaxies, starclusters and planetary nebula images taken on a single evening with my small backyard telescope from the London suburbs with a very sensitive CCD camera in exposures of 100s-400s duration. They show the imaging potential of a small [70mm aperture] telescope despite severe light pollution - no filters, dark or flat calibration frames used!

whoa... are these taken with or without adaptive optics?

[nytecam]

@menono58 without adaptive optics eg and wholly unnecesary with such a small scope !

[nehal0001]

can a 60mm scope do this stuff..???.......

please cument...

[nytecam]

@nehal0001 Yes - a 60mm may be able to do this stuff IF it can track the stars accurately and has a very sensitive camera is attached. Good luck.

@nytecam what d u mean by trackeng objects..?

[nytecam]

@nehal0001 Sorry - to take faint deepsky galaxies etc the scope must track the stars as they move slowly across the sky for the duration of the cam exposure - say 30 seconds or more otherwise stars will come out blurred. The scope can't be static to do this.

man no ofense, u sound like "Marcus Aurelius" from Gladiator

It was taken with his 70mm but........through a camera then refined through his software. *READ*

@786free1 Read the description bro

Hi, can you please clarify (again) were the pictures actually taken by the ETX 70 or were they actually taken by your bigger 12" scope? I have had an ETX 70 and could not see anything like the pictures you have taken. Please clarify with as much details as possible.

@nytecam thanx...
