First moon photo with 60mm Mak!

[StarBru]

I'm hoping these photos transfer as clear as it looks on my phone! My first photos of the moon (I am a visual guy).

Photos taken on March 21, 2021 with my Sarblue 60mm Maksutov f/12.5 (central obstruction is 22mm) on alt/az mount using Motorola Revvlry+ cellphone:
Taken at f/1.7, 1/90 and 1/45th, ISO-100

I'm surprised at the amount of CA showing. The eyepiece is a 20mm reverse-kellner type included with the scope. Could the CA originate from the eyepiece? If it's the optics of the scope, what filter can I use to cut down on the CA?

nice thx

If the telescope is cooled enough the optics should be alright, did you try with a different eyepiece to see if there is a difference?
Any filter you use will change the colour of the image but a fringe killer will work.
You could try a #8 or 11 yellow filter as well but pretty much any CA filter will give a slight yellow cast and dim the image.

Lookin' Good!
I'm a visual guy also, could the CA just be from the phone lense?

Thank you, Gabrielle! A fringe killer is on my list of wants! I have several yellow filters, I will try that first!

I will probably need to use a process of elimination! First, the eyepiece! I also will try a digital camera in place of an eyepiece, and last but not least, a different smart phone.

Oh no! Must not go down that rabbit hole!
