Good Morning to you all, but i suppose some of you may read this in the arvo
Anyway, i would like to ask this.
Last night i had a go at imaging the Horse Head nebula, and at 3 minutes at 500 ISO it was pretty obvious that the city lights toward the east caused considerable build up on the image.
The horse head neb in itself is fairly faint yet there are also some very bright stars in that same field of view.
How do i go about capturing this creature, do i shorten the exposure at a higher ISO or do i reduce the exposure time and at the same ISO as earlier, and take more of them.
Or do i wait till the object is more Westerly and in darker skies, so to speak.
Could some experienced person please assist in what would be the best way to go in regard to time and ISO setting on fainter objects when the light pollution is not that good.
I would be using the Takahashi 106 and the Canon 5D, also the Tak has a Hutech LPR filter behind the rear lens, this dose help a lot with Light pollution, but Im sure there is a limit until there is a gradual build up.
Any suggestions would be greatly appreciated.
Leon
