Re: Rosette Nebula

Marco. If you are using the PI DSLR workflow it is outdated, and frankly, poorly informed, at the time of writing. It was perhaps a step in the right direction. I suggest adopting a different workflow to get the best out of your data, aside from any acquisition errors, which are somewhat fixed, unl...

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?

Re: Rosette Nebula

I just went back and checked the flats....... oops...... :oops: some flats that where not good found their way in the PI stack :oops: 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......

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? Hi Ivo, Sorry for the delay, but I missed you post... no problem sharing the data :-) here the link https://drive.google.com/file/d/0B6oGP3erdtizR1pzVkRTeU1...

Re: Where is the tail of lovejoy?

Hi Starry eyes,
Thanks for taking the time to write the info, much appreciated!
But the procedure you describe is the one I use as well, to be sure I mark the comet in each frame :-)

I will just try again with more frames.....

Re: Where is the tail of lovejoy?

Hi Ivo, Yes I stacked the raw :-) I have tried different DSS settings, the one posted was a median, in superpixel modus. I am still trying all the other combinations, but for the moment no joy :( It could be as Starry Eyes suggest that I'm pushing my luck at f7 with the moon, and local LP (I'm in re...

I have 60 sec, 120 sec sets and a few frames at 240 sec All frames taken with modded EOS1100D trough my Meade LS6" reduced at about f7 and guid...
