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?
I've recently purchase a Celestron powerseeker 114eq and really enjoying it so far, my next step was to purchase some new eyepieces was looking to get the BST Starguiders, however I am now wondering if i should purchase a new scope, my options would be skywatcher 130P/ DS 150P / PDS 200P, budget will be around £500 should i go for a GOTO version and save some more? is the GOTO something that can be fitted to the mount at a later date (sorry if a stupid question).
Will i see a big difference with these telescopes vs what i have already? Is there diffrent scope you would recommend in the price range? Any help would be appreciated
Just a quick question saw a previous post on here for the x-cel eye pieces vs the BST Starguiders was looking at getting a 25 mm and a 10-12mm but would any one reccomend a zoom lens 8-24mm are these any good? If so any particular make I should go for instead of the starguiders or should I just stick to my original plan of getting 2 starguider eyepieces
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
