Just wanted to post a few pics I've taken with my scope and Canon Rebel T5.  Still learning camera settings and trying to get better at focusing.

Used a 32mm eyepiece w/adaptor on camera  and shot some at 25 sec, ISO 3200 and some at 30 sec, ISO 1600.

Welcome to the forum!

Good job with the pictures. Those are all fun targets. With the Dumbell Nebula, I think of it as an apple core.

Thanks guys.  I found an ISO 12800 setting on my camera (by reading the manual, DUH!) and I hope for clear skys to try it soon.

Steve ,
I think you and Spiral should get together. These are very impressive and again to think these were taken with an LX90.
Thank you for sharing.

Alt az.  These are all just straight JPEG shots, no stacking.  I will be trying RAW+JPEG next time.

Nice pics for a first try :)   I wanna get the same Rebel camera too, but maybe with wifi so maybe the 6i.  My question with yours:

 

When you say you used a "32mm eyepiece with adapter on camera" what do you mean?

 

You used Variable EyePiece Projection Adapter and inserted the plossl eye piece ino it then connected it to the camera? or what exactly!

 

I'm not sure what mean.

 

Again, great work

Yes I did use the VEP adapter  with the 32mm plossel. I had the camera connected to my laptop in "live shot" mode. I made a Hartmann Mask last night so I hope to get a better focus next time as opposed to just eyeballing it.

Truly wonderful first images. I had an 8" ACF LX90 and was impressed with it's capabilities. Is your scope the ACF version? 

I also use a homemade Hartmann mask.  The design I found uses 4 large triangles points inward. It also helps with checking the results of collimation . When the 4 triangles are symmetrical, collimation is very close.

Two more areas to look into, to get more out of our setup, are:

1. Focal Reducer/Field Flattener (match the type to ACF or non ACF scope)

2. Stacking numerous images to get more detail and reduce noise levels. 

Keep posting your results and keep enjoying the hobby.

Just so's you know, the name in French for the Dumbbell Nebula M27 is "le trognon de pomme" which literally means, "the apple core"!  Maybe you have some French blood in you!

It is an ACF and thanks for the compliments and advice.  And yes, I think it looks more like an apple also!

I don't think I have any French in me, but there are so many different lines that there could be and I might not know it. However, we had a dwarf Johnathan apple tree in our yard, when I was growing up, that had so many apples on it that the limbs sagged to the ground. I became rather acquainted with apple cores. :)

I am glad to know that someone besides me thinks of it as an apple core!
