Hello and first speedbreaker
Hi everyone,
This is Benji. I am a new member. This is my first post here and I did try to read through some of the sticky topics and normal ones in the Beginner forum to see if I can find a relevant post - my question could be stupid so I apologise in advance but I also know this is probably the best place where I can get genuine unbiased advice.
I have been doing photography for a while now with landscapes and events so I know the fundamentals - or so I thought before I purchased my Saxon 150/750 on an eq3 mount as I was fascinated by celestial object photographs that people have been sharing on various social handles. I wanted to try and see if I could do it.
These are some details which may help assess my current situation :
I am in Victoria, light pollution rating Bortle 6.
I have polar aligned the scope to the South Celestial Pole and have aligned the viewing scope and the telescope .
Collimation might be very slightly off but I am working on it.
I have a T ring and the 1.25” nosepiece for my D 750 to go into the focused but I did read that due to enhanced distance from the focal plane with this setup, my camera may not acquire focus. I searched on YouTube and saw an individual recommending to take the thread part of the focuser off and put the T ring directly screwed into it to reduce the distance between focal plane and sensor ( I hope I am using correct terminology here). With this setup I can achieve perfect focus during daytime with my camera. At night, when I use the camera in live view and zoom right in, I can see stars and they look ok. But when I take long e posters say around 10-30 sec across ISO range 800-3200, I get nothing but a gray blob and an imprint of my front assembly in the picture. I have attached a sample picture - I had two thoughts : light pollution or incorrect settings. But I cannot work out why I see that imprint in the photos. The moon rises pretty late so I was trying to point at Carina yesterday.
Any guidance you can offer will help me focus more on my skills and not be disheartened so early on.
