Hi, I just got a canon eos 600d to take pictures with my skywatcher 200p scope. I am using prime focus with it which seems to work fine despite the problems people face with getting it to focus. I plan to get some great shots of the moon, planets and orion nebula but I was wondering if theres a way I can get shots of dimmer objects in the sky. At the moment i am finding this hard as I am limited to a 1.5 second shutter speed in order to prevent star trails, I am putting the ISO up high to get the most light but I was wondering if there were better ways to go about getting the best pictures without a tracking mount. Thanks.
Hi guys, hoping you can help with the tracking problems I'm coming across with my astrophotography setup. I've been using it since August 2020 and have kind of put up with the problem until last night where I think it's getting worse...
Specs below (let me know if you need anything else):
William Optics Zenithstar 61 II (360mm F6.1) - Zenithstar 61Adjustable Field Flattener iOptron SkyGuider Pro Camera Mount Full Package K&F Concept Aluminium Tripod with 2kg weight Canon EOS 250d (cropped sensor 1.6x) The problem:
I take roughly 40 pics with each being 1 minute long at 1600 ISO and stack them on DeepSkyStacker. From a few people I know on the internet, it seems as though, with a very similar setup and same focal length, they can get around 3 mins of exposure with no problem. And that's without a guide camera.
With my 1 minute exposure, roughly 10 of 40 images are reasonable but the rest have star trailing or double stars (see attached downscaled, unedited pics of Orion nebula)
What I think it could be:
My first idea was the tripod, it's not the best but it's not cheap plastic, and it should be fine for a 1 min exposure. Then I thought it could be the iOptron tracker that could be faulty?
Every screw has been tightened, there's no play in any of the adapters/mounts.
I thought I'd post this here to see if anyone else has the same problem or has more experience/knowledge that could help. Also to see if there's an obvious problem before I spend hundreds on a new tripod or send the tracker back for a replacement.
Any help would be much appreciated!
Hi, I got a skywatcher skyliner 200p dobisonian a few days ago, my first observing session was out in the cold and the telescope dewed up when I bought it back in. I then noticed that the glass on the base of the telescope(not the primary mirror inside) was smudged and had a little ring shaped scratch on it. I tried cleaning with a lense cloth but it is still slightly dcratched and smudged. Does anyone know if this makes a difference to the inside primary mirror?

On September 18th 2020, I was observing Jupiter through my C8, with 26mm eyepiece and had my Sony A9 attached for eyepiece projection when I noticed the ISS make a pass overhead.
I set my A9 to 1/800 sec and ISO 2000 and was able to capture a pic by hand guiding my guidescope and keeping the ISS on the crosshairs.
I was pleasantly surprised by the outcome, comments welcome at my first attempt at imaging the ISS.
I know it may be a bit of a long shot but I'm looking to buy a HEQ5 Pro mount or an NEQ6 Pro or something similar. Preferably belt driven but not necessary as can happily modify it. Please let me know if you have anything! Thanks.
