<p>As I mentioned back in HPR 3857 "Yesterday I saw a flare" I have put together a way to take images and video through my telescopes, and more. You can do so too for under £100, assuming you have your own telescope, or add on another £40 for a nice lens for the HQ camera instead of a telescope.</p>

<li>Meade ETX-90EC - a good telescope in its day and worth using if you have one lying around but not something I'd recommend buying these days. Only available second hand.</li>
</ul>

<p>Here are some images I took with the above kit:</p>

<p>The Sun in H&alpha; using a Coronado PST solar telescope. 50 or so stacked with exposures of 20ms for the disk and one 100ms to pick out the outer, coronal features.</p>

<p>Star trails using the C/CS mount lens. The bright white and red blobs are due to my headtorch and during the end fog rolled in and coated the observatory in ice in under fifteen minutes!</p>
