Eta Carina - wide field - mosaic

[jsmoraes (Jorge)]

GSO 305 mm - Canon T3 - ISO 800 - 4 x 5 x 4 min (80 min) - OAG - Skyglow filter - Coma Corrector

I am not very glad with this work. My set distort the image at periphery and I can't assemble the mosaic with perfection. Some areas of final result have a strong error of star position.
Other issue is a black frame border for each photo. Clean them is very hard.

In short words: my set isn't good for mosaic !

I did a test with the photomerge function of Photoshop and the result was better. It got better alignment with geometric and vignette correction.

Atached are my processing and the photomerge processing

The image are with Autosave.tif 32 bits from DSS. I will try another graphic processing to see if with the photomerge I got a better final result.
