Re: [APML] Lagoon and Triffid Region

Really deep Loke. The HC110 plus the red channel composite was excellent
strategy for this high dynamic range target. Schmidt cameras are just
capable of sooo much with the TP. Excellent work. Would you post a high res
shot for us to see just what that Schmidt camera is capable of on TP?

Have you ever attempted mosaics with the schmidt shots?
