Reprocessed LMC

[avandonk]

Found some images I took on boxing day last year so I decided to process them with ImagesPlus.
Details Canon 5DH,Canon 300mm at F2.8. ISO 800. 8x60sec with nebula filter, 14x60sec with LPR filter. Processed both lots with IPlus and Registar seperately. Then used Registar to stack and SUM the result of each.
Then used IP to digitally develop this resultant sum. Here is the result.

Very detailed result Bert. Perhaps a little too pink on the far right hand side for my liking. Is that still part of the LMC?

[avandonk]

I think it is caused by light pollution gradient. It is very difficult to get all the faint nebular detail to show without exagerrating any gradients present.
This is one of many objects I hope to image from a dark sky site once I get everything finally fine tuned. That day is very close. The extent of the LMC makes the use of any gradient removal tool also remove some real detail. I only put this up while I tried to remove this gradient.
Here is a better result of gradient removal from the same image using GradientXterminator without any further adjustment of levels and curves etc. Thanks for the critique it keeps me thinking more objectively about what is real and what is artefact.

That's a much better result. Excellent job bert!

Bert that is something special.
Fantastic!

Wow, beautiful image Bert - looks great at 1600 x 1200 full screen. The smaller IIS image just does not do it justice. Well worth a look at the bigger picture.

Cheers

Love em both, but , I think the reprocessed image is far more subtle .. What a stunner !

[ballaratdragons (Ken)]

You've done it again Bert!!!

Another stunning widefield!

It is great to see all the splatter from Tarantula and surrounding objects in one shot. Gives it all 'perpective' and makes it easier to understand where all those objects are in relation to the main mass of the LMC that we usually only see in close-up pics.

Great image Bert. When I got your lens the LMC was getting lowish just on dark, and I dont think I got the best your lens can do, but now its rising in the early morning I will have to get up early and use your lens on it again.

I think I finally know enough about processing to tackle the LMC data I have. Here is an image from March 1st 2006 data. I was really stuck with gradients as the field is so large and the LMC is in the direction of the worst light pollution.
Details Canon 5DH, Canon 300mm at F2.8, 10x60s and 6x240sec ISO 800, Hutech LPR filter, processed seperately with IP, stacked with Registar, digitally developed with IP and combined with Rgst , GradientXterminator and finally PS for levels and curves.

As you can see the data is much better, and focus is almost perfect. When I make more room on my webspace will put up the 9MB image if anyone is interested.
This little exercise has taken two full long days to get it right. I hope you all enjoy. I am sure I still have more to learn.

Good one Bert,

That lens is a real performer.

Here is another taken with the 100ED at F6.4.

Both are superb, but I think I prefer the 300mm version.

[xelasnave]

mmm I am no expert but the 100ed seems rather good to me, excellent really
