You can elaborate image two times. The first for the faint part, the second one for the core. Than you can stuck the two images to have all the details in one
I have a simple question. I'm trying to use a 1.25" .5x focal reducer on my Meade ETX 90mm. This scope is 25 years old, but it's still works well and it's still made today by Meade Optics. Does the focal distance change to a closer length? I tried it with any eyepiece and it the field is reduced. When I use it with my T2 camera adapter, I am either to far away from the sensor or to close. I also get vignetting and the image doesn't focus properly. So I must be overlooking it. What am I missing here? I thought by using a focal reducer brings the focal length even closer to the sensor. Is this correct? Attached is my setup. Captured the moon on my DSLR on this scope. The focal reducer is supposed to screwed into the 1.25" barrel. I have 2 different focal reducers. I have tube extensions and I also brought the reducer closer to the camera sensor as close as I can get. It didn't make much difference. I can't achieve back focus. The total focal length of the ETX is 1250mm. What would it be with a .5x reduction? I get the same results in either case. I'm not giving up on this. I'm using IR and visual filters that's 58mm in diameter. So I can use my DSLR filters. Help and thanks! Can you advise me on what I should try next? I'm trying to fit the super moon in view.

For some reason when I right click a red square in the background extraction Siril crashes and closes. I reinstalled it but still the same. Any idea why? I have a MacPro late 2013 running macOS Monterey.
@@astrolotl528 polar alignment is pointing your dwarf 2 in the direction of the north star, basically changing the dwarf ii function from alz/alt mode to equatorial. That reduces field rotation leaving you with a larger more workable image. I have that explained in my dwarf ii astro tutorial. Feel free to check it out(ᵔᴥᵔ)
Seems like I learn something new every time I watch one of your vids. I never noticed the OSC preprocessing script with Drizzle.
Nice. You should try lowering the highlight protection in GHS to protect the highlights like the core.
Thanks for the advice🙏🏼

Great Video! How many lights did you take for this m31 example?
999 15s exposures

Wonder how much clearer the ZWO SeeStar is...
How did you get a wide picture of the Andromeda Galaxy with dwarf II I tried and it is too zoomed in?
The Andromeda Galaxy should fit fine the dwarf 2 has a fov of 3 degrees so it should fit easily.
@@ScottCastrophotography it just looks like there is more space in the image you are editing but alright
@@astrolotl528 i did polar align my scope did you polar align yours?
@@ScottCastrophotography is that goto? Sorry I'm not that smart, but if that's it, I did do that

@@ScottCastrophotography what settings did you use on the dwarf?
And i the 2nd🤌
Hello!😄 I'm working on an astro function tutorial for the dwarf ii coming soon! Can't wait to see what you think!
@@ScottCastrophotography ！！！same Scotty！Go get a distinction🤣
