<p><BR/>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>I haven't dabbled much with Solar Imaging but recently tried my hand at it with my new Monochrome camera (Imaging Source DMK21AU04.AS).. The telescope used was a Coronado SM60 (a dedicated Hydrogen Alpha scope). 23rd March 2008: Active regions 987 & 988 At reduced magnification. Prominance 26 March 2008: Three days later you can see the active regions have moved across the Sun's disc, showing the sun's rotation. <br />Posted by RixPJ</DIV></p><p>Very nice. For those that have never seen the sun through a H-a filter, it's an amazing sight. I had the opportunity one morning at the Lowell Observatory. It was the first time I'd ever seen such a view live, and believe me, the sun was alive. I watvhed for 15 or 20 minutes as the view changed.</p><p> </p><p>Good reminder for the to get thraining on our H-a filter at the observatory so I can get it out for our Sunday afternoon public sessions.</p><p>My first duty sessiin is a <font color="#ff6600">SUN</font>day afternoon.</p> <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.
