I am new to astrophotography and of course started by taking a photo of the moon (as attached) using my Canon EOS500D camera - 1/250 exposure time, 800ISO. I used my celestron 127EQ telescope with a adapter for the camera of course. I used no eyepiece.
However, i find that it is slightly blurred, and upon taking pictures of nearby stars, i also found them to be blurred, even with a high exposure time. am i doing anything wrong at all or is this simply because of my setup?
Hi, I'm a beginner and I want to buy something for my telescope. I have a Bresser 6 inch Newtonian(750mm focal length) I have 2 lenses, 9mm, 25mm, a moon filter and a 2x barlow. What would be the next thing to get? I was thinking maybe a solar filter, a light pollution filter since i am stuck at home, idk. What are your thoughts on this?
I've been seeing tear drop shape stars with the EdgeHd 8 and ZWO ASI294MC Pro camera, so I verified the collimation. I'm using a celestron x0.7 reducer.
Does collimation needs to be checked with an eyepiece or with the camera and with or without reducer? I'm asking since I verified my collimation yesterday and couldn't see the concentric rings with the complete imaging train (ASI294MC, OAG, and x0.7 reducer). It was only showing the inner shadow and outer circle. I than replaced the AS294MC with my guide cam (ASI120) which has a much smaller sensor and could see many rings. While, to my view, it seems to be collimated, it's strange that I can't see the rings with the main imaging cam. Any thoughts? Here's how I left the collimation after some adjustments with the guide cam.
I'm brand new to the forum and new to Astro. I've been loving it since January and learnt a huge amount by myself with the help of forums like these.
I recently purchased an iOptron 10" RC truss. 3" focuser with a 2" compression. I have been using a WO FLT 132 before this which is little more forgiving. I have attached a couple of pictures from my first attempts. I am not using a field flattener at this point. (just getting used to collimating and setting up). Camera ZWO ASI 6200 MC cooled camera. The images below are composed of 50 x 5 minute subs stacked in pixinsight with basic image processing. I'm using PHD II and a WO guidestar 61 and ASI 120 for guiding on a CEM60EC mount. Drift alignment in PHD 2. Any ideas as to the main causes of egg shaped stars? Could this be sensor tilt? crappy guiding? Focus also looks off? Any help appreciated please
So on Tuesday night I spent the evening imaging the moon with my Celestron 9.25 SCT and DSLR as shown below and am happy with the images I collated (I only took images as I did intend to take capture video but I got carried away and time was getting on).
I have approx 350 jpeg (and the equivalent in raw) images and have used the Microsoft image composite editor to stitch the frames together without editing them first etc but I wonder if I'm going the images an injustice?
I'm not ready to pay for editing software as I know there is a lot of very good free downloads out there and I'm asking for recommendations. Should I be processing the frames before/after stitching and what software would you recommend? Please offer any advice you have.
I will post the resulting image once I'm happy with the outcome 😁
Thanks in advance!
