Rosette Experiment

et's say images A and B are still linear and framed to make a mosaic, A on the left, B on the right. Ask Registar to register and calibrate B and then combine them. Save the combined image but also save the registered calibrated version of B on its own. You may need this as a 'patch' panel.

In Photoshop stretch the combined image not all the way but hard enough to reveal any defects in the calibration but record your stretching as an action.

Do you think I could do the register stuff and then use Pixinsight?  I would definitely need specific assisstance.

I rather doubt it because PI won't let you use brushes to remove part of a layer, so far as I know. I dare say it could be done in freeware like GIMP.

Bummer.   That seems to be the state of the universe right now

I have imaged the Rosette Nebula 3 times at 3 differnt focal lengths (318 mm, 480 mm and 700 mm).  I managed to work each idata set into a version I could live with (after much time!).  Each image consists of 14 hours, 24 hours, 13 hours respectively.  I wondered what would happen if I combied them all into a 51 hour image.  So, becuase I do not know how to insert higher resolution data into lowere resolution widefield data (Any advise on how to do that would be very much appreciated).  So, I registered all data to the smallest FOV (which eliminated the need to crop the combined image), combined the 3 images,then inserted the lum of the highest resolution image (700 mm)-- Well--here it is.  I do miss the wider FOV, but still a satisfying endeavor.

 

That’s a belter Rodd, very nice processing, esquisite detail
