LMC With the Acro

[nebulosity.]

Put my little 110mm F4.5 acro on the iOptron IEQ45 last night as it was to windy for the 8 inch. Did a quick polar align and a one star align for the GoTo and was off, every object selected was smack bang in the centre of the image, I think I'm starting to like this mount :D

Anyway this is obviously the LMC with NGC 2070 and all the other neb's in the region, taken with the said scope and mount and Canon 1100D. Unguided with no filters. 52x66 second subs processed in Nebulosity and Aperture.

Please ignore the CA, I've done my best to reduce it's still there :(

All tips and suggestions welcomed.

Cheers
Jo

Oh, and the ISO was 3200 :thumbsup:

Unguided, no filters, 52 x 66 secs exposures ! Other than some slightly 'eggy' stars at top left that's a pretty damn good picture.
Well done, I'd be happy with it.

Nice shot Jo. I'm still trying to figure out that spider neb. The colour can go from cyan to red depending on the camera and / or filters used. There must be plenty of OIII in it to compete with the Ha. If you were to shoot it with an LP filter, it seems to change the balance to red Ha.

One thing, do you use an IR / UV block filter? That can help reduce some star aberrations on most refractors without losing any important information.

Jeez that's pretty good Jo. Nice capture. The Tarantula really has a boatload of O3 in it doesn't it? Makes for a good comparison with the Horsehead - which has none.

Cheers,

Nice image Jo.
You can reduce the CA around the stars a bit with photoshop.
In adjustments, choose hue/saturation. Then change "master" to magentas.
You can move the slider or reduce its width to best match the colour you want to reduce. Then reduce the saturation - this will make the purple colour lighter (or even white). Still not ideal though.

Thanks Brent :thumbsup: glad you liked it, not sure what coursed the 'eggy' stars :question: I think I need to adjust the collimation.

Thanks Kevin, yeah hard to know what colour is right, this is an unmodded camera so I guess thats keeping the red back. Good idea about the IR/UV filter, I'll give it a go.

Thanks Cam :D



Thanks for the input Tony :thumbsup: great to know some extra tricks for reducing CA.



Thanks Col :thumbsup:



Cheers :D



Thanks a lot :)

If there are a number of different gasses in the nebula then there is no right or wrong way to image it. It comes down to aesthetics. Blue or red, both are good!

Nice going Jo, lot of short subs are kepping them Stars under control whilst using the Achro, dug out some good neb around the area aswell :thumbsup:
Great going ..
