Description

Updated image -

The original image was stacked with Deep Sky Stacker and for some reason the entire image was red ??  I'm now using PixInsight and the colors have changed.

I started using an electronic focuser and it is really doing a good job - my stars are smaller and the images are cleaner.
I used three different filters (IDAS GS1, Optolong L-Pro and L-eXtreme) and integrated all the images together. I'm experimenting with different filters and different ways of processing.

I have recently moved to a mono camera and will redo the Pelican Nebula sometime in the future. Right now I only have LRGB filters and may try them on the Pelican. Eventually I will fork over the big bucks for narrowband filters.

The image that came out of Pixinsight was a bit washed out so I used PixelMath to bring out more red -

Split the image into its R,G,B components with the RGB icon at top left of PI
Open PixelMath
Uncheck 'Use a single RGB/K expression'
Set R/K to - (Red * 1.3) // could use 1.2 or 1.4
Set G to - Green
Set B to -  Blue
Click the 'Apply'

Pelican Nebula - This is one of the first images photographed with my new 8" newtonian. I'm about 5 months into this hobby so there are a lot of improvements yet to come.

The Alabama summer has been hot(70's at night) and humid(80-95% at night). I will redo this image when the humidity goes down and the evening temps allow me to cool my camera to a lower temp.

I just purchased a QHY PoleMaster Electronic Polar Alignment Scope. I'm hoping this will help with a drift problem I've been having. I may have to go to off axis guiding ?

I'm also having trouble getting my telescope correctly collimated. I probably should have started off with a refractor.

I would appreciate any constructive criticism or suggestions.

Update: I stopped using a laser pointer to align my secondary mirror and my collimation has gotten better. It seems the laser pointer is good to align the primary mirror but not so good for the secondary. Most laser pointers are out of collimation from the factory, I found 3 collimation screws and adjusted my pointer.
