Rosette Nebula
Rosette Nebula
The Rosette nebula 5000 light year distance
Taken with my modded EOS1100D with canon zoom lens 55/250 mounted on an iOptron skytracker V2 with Triton tripod and ball head .
It is only 54 minutes of 120sec lights ISO 1600 f 6.3 with the lens at 250mm
13 flats and 35bias
Imaged and focused with APT
Stacked DSS
Processed in StarTools

Re: Rosette Nebula
Hi Marco,
The Rosette is recognisable, though I'm wondering if more can be teaed out of the data.
Any chance you could share the data with me?

Sorry for the delay, but I missed you post...
no problem sharing the data
here the link

Thanks for the input!

Re: Rosette Nebula
Thanks for going through the trouble to upload the datat!
The data is severely compromised and certainly not something one would expect for the quoted exposure time and application of flats+bias! Something must've gone wrong somewhere...
Have you tried stacking this in PixInsight?

Not yet still trying to get hold on PI way of doing things....
I am putting this images in the to-do list
will revert as I have results.

Re: Rosette Nebula
Hi Ivo,
I succeded to do a stack and integration in PI.
2 versions:
This one made with PI BatchProcessing script:
https://drive.google.com/file/d/0B6oGP3 ... sp=sharing
And this one made by manually doing all the steps in PI
https://drive.google.com/file/d/0B6oGP3 ... sp=sharing
this second one looks maybe a bit better to me (easier to process in StarTools), and the both looks very different from the DSS staked version.

Re: Rosette Nebula
PI made a pretty big difference there, though those gradients and vignetting are really quite something - it appears the flats either made no difference or made the problem quite a bit worse.
What does the data look like w/o flats and bias?

Re: Rosette Nebula
I just went back and checked the flats.......
oops...... some flats that where not good found their way in the PI stack
Thaose flats where taken with the T-shirt method holding a light before the canon lense, and in few of them the light was not really evenly illuminating the sensor....
will redo the stacks...
Thanks for the head up

Re: Rosette Nebula
Hi Ivo,
here a stack without darks bias and Flats.
looks to me that even if the flats were helping with the vignetting,they were also causing lots of problems.
Or could have been the darks and bias to cause the problems?
