Title: My first ever M42!
Post by: Rocket Pooch on Nov 07, 2004, 00:58:00
Hi,

This is my first ever M42, taken with the 80mmF5 scope and consists of 25 1sec, 20 8sec & 3 20sec stacks, combined in Photoshop, I did not remove a flat mask so I've cropped about 30% of the image out.

This was taken using the SAC8 with no filters, I even forgot to put the IR on :sad:

Hi Chris - Nice image - I know M42 has always been something you wanted to capture. Could you possibly post one each of the the 1, 8, 20 sec Raws - I like to have a look at what magnitudes you were able to image to with the various exposures.

Cheers,  John

Hi Chris,
Images are looking good I love the apostrophe that is M43. Do you know what is causing the dark shadows on the bright stars? Is it a processing artefact?

This is old school, but the shadow is actually from the camera, it transmits to the control box in RF and obviously the control box is not tunes in :smile:  I must see if there's something I can do about it.

See ya

Thks - I love the nebulosity in the 8 & 20sec images - We will have to try & get a few colour images with the TouCam & see if we can combine - I'm sure it would look very impressive - John
