ETX-125 AT- moon photography problems

Postby Majed » Sat Apr 28, 2018 9:37 am

Hello my friends,

I am new here, my name is Majed. I hope to learn from you all that is new,

My first question about Meade ETX-125 AT, Two nights ago photographed the moon through this telescope by used (T-mount) part number 07384LF and Meade # 64 T-adapter to connect the camera canon 600d

But I could not fit the moon disk inside the picture !!!!!!!!!!!

So I got in touch with Meade customer service and asked if there was a focal reducer for this telescope, and told me this is not anything ever made or sold for ETX.

So I need your advice and opinions as experts on the subject
Majed

Hi Majed, and welcome.

The ETX-125 is a Maksutov design telescope, so it has a relatively small field of view.
I can't advise about a focal reducer, though this article here suggests you might be able to get a "back cell adapter" which allows you to use one.

However, for imaging the Moon, a simple alternative is to take 4 overlapping images with the same exposure settings and use software such as Microsoft's Image Composite Editor to combine them into a mosaic covering the whole disc.

ICE is very simple to use, you just select your 4 partial images and it matches up the joins to make a complete image which you can then save

Best of luck, and we look forward to hearing more from you about your astro adventures.

Edited to add
Here's a mosaic assembled by ICE from 28 individual images - it's not particularly good, and I've not done a lot of Post Processing, but it shows what can be done.

Thank you for your quick response to my question

But now I'm planning to buy : Meade Back cell adapter - Etx to SCT threat #
07036
---
Meade f/6.3 Focal Reducer / field flatterer

Does the problem end?

I'm afraid I couldn't tell you, but it sounds interesting, and if it works it'll make your scope a lot more versatile.
Let us know how you get on.

I do not want to risk, especially I will buy them from outside the country,
so I need clear advice if possible

I'm very sorry then, that I can't advise any further; but do try taking the multiple images and combining them in ICE. It really is very straightforward.

I think this method may not be useful, because I am now planning to photograph the total lunar eclipse on July 27, 2018, and for me better to be prepared early

any way thanks for your time

If you've decided not to risk buying a focal reducer across the border, you may as well try out using the multi-image approach.

A lunar eclipse occurs over a long period of time, and you only need to move the scope a small amount each time, so it doesn't take long to take a set.

I'd suggest you try it out as practice at the upcoming Full Moon and see how straightforward it is.

I want to get it. I want to try something new. Acquire new knowledge to develop my skills in astrophotography . But at the same time I want professionals to give me their advice.

I already have other telescopes and zoom lenses but I have not used this telescope (ETX-125 AT) before in astrophotography .
