Experimenting again

[Zeffer]

At last had a decent night's observing. Once I had gotten over Saturn I tried a few images. Really experimenting with different configurations. Struggled with focus this time, not sure why, but here they are anyway.

M42 at prime focus - ISO 800 at 30 seconds:

M38 - same settings as above:

Then I piggybacked the camera for the first time so this is the Hyades at 70mm, ISO 800, F4.5 at 20 seconds:

The I used my focal reducer for the first time and tried the Double Cluster, couldn't quite get it there before the dew came and ended my fun, so not the best shot - ISO 800 and 30 seconds:

It was fun trying different things out and now I have to do a study on one subject for the night and try to crack it.

cor! Fantastic images. Really excellent results - perfect focus and tracking.

Good images Zeffer. Now take 20 identical images of each and stack 'em using Registax v4. You will be blown away by the deatil that jumps out.

Good luck.

Great catch there Zeffer

Nice ones 8)

[MartinB]

Excellent stuff Zef. I particularly like the star colour in the double cluster. Nice pin point stars as well

[SteelRat]

Yup - nice stuff Zeff. DC cool 8)

Thanks guys - I really must have a go at stacking some images. It's such fun taking the pictures but one day I hope to get a glorious one like Roger or Martin etc. which means I must start stacking. I won't forget that day!

Well done Justin , a great set of images , and well on the way to your for your future imaging ,

Help please!

Tried to stack 12 images in Registax 4 but keep getting these wierd lines through the final image and only the centre of the picture is any good. Any ideas?

[CELESCOPE]

heck i,ve not got version 4 Justin , but looks like the alignment process is failing for some reason, i presume you are doing it right , have you version 2 , to try and see if that works any better , i still remain with that , perfectly good enough for normal stacking , but maybe someone who has v4 can throw some light on it ,

Field rotation mate. The image is turned between the images so either the alignment is slightly off or you accidentally turned the camera.

Is there a program that deals with field rotation? I think the nature of my scope is that I will get it but I'm not sure.

[CELESCOPE]

CC after imaging with alt az for many years ,i found that if it was field rotation in registax that would show up on the stars , this i believe to be an alignment problem , i could go up to 30 secs no prob with the set up Zeffer has no probs , after that then yes i had to use Maxim to overcome that , so i dont think it is that ,i may be wrong . lets hope zeffer find the answer soon

Just looked at it on a different monitor, it's because more than one alignment point was chosen.There's a "pane" for each point. Registax 4 does this and I don't know how to cure it. Use one point and it's not a problem.
