I have spent a few days trying to get my main camera and guide camera to focus together. finally found a combination that got them both focused together the problem is my back focus is now 121mm. but does not seem to bad of an image.

This is orion

1.2s subs at 350 gain

no darks frames

90 stacked frames

plate solved

bining at 2 so I could see more of the image

cooled at -15

there is no processing. I saved with adjustments open in wondows photos and resized for forum and then opened in flatroom to save as jpg.

Thanks

It would be a good idea if you posted a screen shot that has your live view stacking histogram.  You can either do a screen capture or use microsoft snip to get part of the screen

 

For this object, I would expect a 90 second stack to show much, much more of the nebulosity, and the core would be blown out.  My guess is that you have the black point sent far to the right.
