        <p>월령 2.8일의 손톱달, 아직 해가 채 저물지 않은 저녁 노을 속 고도 25도 남짓의 월면으로부터 고해상도 이미지를 얻는 일은 사실상 불가능에 가깝지 싶습니다. 월면은 어둡고 얇아 대기의 요동에 취약한데다 지표면에서 끓어 오르는 상승기류의 직격탄을 맞지요 - 보고 있으면 멀미가 유발될 지경입니다. 이 날의 시상은 Pickering 3/10에 불과, 게다가 아직 열평형(thermal equilibrium)이 이루어지지 않은 시점에서 지표 근처에도 강풍이 부는 상황이었죠. 마냥 좋은 조건을 기다릴 수만은 없는 법, 어제는 이와 같은 악조건 상에서 월면의 촬영을 시도해 보았습니다.<br /></p>

<p>여러가지로 사면초가인 상황인데 적절한 타협점을 얻는 것이 중요하겠지요. 결국 이와 같은 상황에서 굳이 월면의 고해상도 이미징을 노린다면, Planet IR Pro 시리이즈와 같은 적외선 패싱 필터를 쓰되 가급적 감도가 높고 노이즈 발생이 적은 CCD 카메라를 사용하는 것이 좋겠습니다. 위 사진을 촬영한 Lumenera LU075에 비해 감도가 좋은 <a href="http://www.hackthedot.com/index.php/equipment/dmk_21af04.as/" id="71a79ac2f903537ce3cc84adb1321d38" name="71a79ac2f903537ce3cc84adb1321d38">Imaging Source DMK 21AF04.AS</a>를 활용했더라면 좀더 나았을지도 모릅니다. 또한 게인을 필요 한도 내에서 최소한으로 낮춰야 화질을 유지할 수 있는데 현재 배송 중인 <a href="http://www.hackthedot.com/index.php/equipment/astronomik_planet_ir_pro_742/" id="71a79ac2f903537ce3cc84adb1321d38" name="71a79ac2f903537ce3cc84adb1321d38">Astronomik Planet IR Pro 742</a>의 경우 807 모델과 비교했을 때 740~800 nm 영역대의 적외선을 추가로 투과시키기 때문에 기본 화상을 좀더 밝게 가져갈 수 있습니다 - 게인을 낮출 수 있을 뿐 아니라 밝은 월면 외에도 목성, 화성 등의 밝은 행성에도 적용해 볼 수 있을 것으로 기대하고 있습니다.</p>
