Is there a way to combine Ha with LRGB in Astroart? eg Ha + L or Ha + R. Or is this best done in another software program? Thanks. You can experiment with combining Ha with LRGB using the Color drop down menu and/or the Arithmetic menu in the free Astroart 9 demo: https://www.msb-astroart.com/down_...

A quick query - how do you remove crosses marked on images?

Just right click and drag the mouse cursor on the image.

Wow! Great news.

I added dithering to the above script. You can select the dithering type and parameters from the Sequence Tab and Guider.MoveReference will use these when no parameters are specified in the script. Remember to click on the Dithering check box I added: Guider.MoveReference Pause(3) Pause(3) gives the...

The two frames (8 +7) in the upper left were shot when the scope was aimed fairly low (35d altitude) and atmospheric dust seems to have effected the images. I am sure there's a way to compensate to make the image more nearly seamless but I may have to reshoot them. The original 8 frame mosaic comes ...

Here I used AA9's Star Atlas mosaic generation feature to produce the target coordinates for an 8 frame mosaic of M31 using my 10in F5 SCT and an ASI071 camera. I am still working on the fine details of this to produce a near seamless image. I reduced the attached image to 1/4 (25%) size to allow me...

I was able to use the above script to goto and image about a dozen different objects last night! I waited until a nearly full moon to test going full robotic from now on. Also I was able to use the AA9 Star Atlas Mosaic feature, which is extremely useful: I used my 10inF5 system. I ensured that my c...
