Skymax 150 or 180 Top Dovetail bar?
Laurieast replied to Laurieast's topic in Discussions - Scopes / Whole setups
😱 I was thinking something more like this: https://www.firstlightoptics.com/stellalyra-telescopes/stellalyra-8-classical-cassegrain-vixen-style-dovetail-bar-radius-blocks.html -
Can you fit a top dovetail bar to either the Skymax 150 or the 180? I did a search and found somebody had done it with rings, but I would prefer not to do that. Thanks for any insight!
-
I just put that in Stellarium, but it looks different to the chart in the link above 🤔 Edit: Maybe not after all.

Much better. Does GIMP have this, or similar? Select/Inverse, darken the background a little (levels), I can see your pasting or masking.

Questions are good! I would be guessing if I answered that, I have never used one. I have a cheap 1.25" 2x Celestron barlow, a 1.25" 3x SV Bony barlow, which is good, but with your sensor maybe not, and a 2" 2x ED barlow https://www.firstlightoptics.com/barlow-eyepieces/skywatcher-ed-deluxe-2x-two-inch-barlow-lens.html There is an informative thread here about focal extenders: https://www.cloudynights.com/topic/665643-difference-between-focal-extender-and-barlow/ It looks as though it gives a flatter field, but if it would work with your kit 🤔 , it would be good if @vlaiv saw this and may have some better answers.

Wow! -
Yes, a little, try with curves adjustment. With your second image imposed on top of the one with the moon's. maybe a bit bright 🤔
-
Well done you! Progress! 😀 Yes, the second one dose have the edge over the first one.

Thanks. What is the second number? the [0.0868] ?

What filter was it? How did it get so red.

I have Photoshop not Gimp, but same idea... Copied your colour pic Made into 16 bit Adjust the colour balance Adjust the Curves Took the brightness up a little. Taking up the Exposure seemed to wash it out.
