<p>So what would I need to purchase? I'm thinking of getting the EQ1 or 2 just to experiment with it, so I need to buy a motor for it to automate the tracking? or is there a way to manually set it yourself?</p> <p>Thanks Glenn! damn i wish I had a Mac, that would have been convenient </p>

<p>Ahh I see! thanks again~! do you have any experience using the EQ1 or EQ2. I did a bit of research and a lot of people recommend the astrotrac system but it looks like it's around 800$ I also heard the EQ5 is good as well</p>

<p>Cool thanks Michael! I understand that trailing depends on focal length and shutter speed, but what I was asking about the light frames is how many light frames should you take? I heard around 20 to 40. So If I'm going to take for example 20 light frames at 30seconds per frame on my wide angle lends at 11mm which will not cause any trailing. When you stack those 20 frames in deep sky stacker how will there not be trailing? Your taking 20 pictures of the same scene every 30 or so seconds 20 times then stacking them together should'nt that in itself cause star trails to appear? how to people get crisp stacked photo's of the night sky with out star trails, maybe I'm not understanding something here.</p>

<p>Hey y'all,<br> So I have some questions about photo stacking, I can't seem to figure it out. Just wondering if anyone could help to simply explain what the process is. I can only seem to find a lot of convoluted explanations.<br> So first I understand the <b>dark frames</b> you take about 20, lens cap on and with all the same settings as the light frames. And take them right after you shoot your lights.<br> Then <b>Bias frames </b>also take about 20, same settings as light and dark, lens cap on and shortest possible exposure. take them right after you shoot your lights.<br> <b>Flat frames </b>so I've heard a few things, from my understanding you use the same settings as the lights, darks and bias, but you cover the lens with a white T-shirt or something then smooth out the folds then take 20 shots but at a bright light or at the sky?<br> So my 2 questions are, first regarding the flat frames, what is the easiest way to do this? during the day? in the morning? what will produce the best results, and is the least complicated.<br> My second question is I do not understand the light frames, I heard It would be ideal to have between 20-40 light frames, but if you are taking 40 frames of the exact same scene at say 45 seconds or whatever, are you not going to get trailing when you stack all of the photos together?? or do the stacking programs correct for this?<br> Thanks</p>
