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 everyone - juts purchased my first telescope and am asking for advice on what is best to be seen through this telescope as a starter - have already seen the moon and some distant stars and am comfortable with using all of the eye pieces included. What would anyone recommend?
SkyTech L-Pro Max Light Pollution Suppression Filter
Used for about a year now and still in very good condition. really helped me out in my garden but now I've moved to tougher skies and need a slightly stronger filter. So it's time to pass this on to someone else.
Filter is in very good condition with no scratches on it. Used extensively to great effect. Cardboard box slightly tatty but to be expected.
Creates very nice pictures with good star colour retention and no halos. Horsehead is a HaRGB composite photo where the RGB was shot with this filter.
2" fitting (M48). Will come with outside box, interior box and of course the filter.

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
