This object can be framed either as shown or with a much larger frame of almost triple the size to show additional areas of nebulosity to the right of this image. Faint reflection nebulae require a dark sky site for imaging. You will be disappointed in light-polluted suburbs. Luminance layering with LRGB techniques help to collect light faster for this object. A single-shot color camera would need very long exposures. Processing. Routine luminance layering techniques are suggested. After histogram adjustments with digital development or levels/curves, gently sharpen the areas of brighter nebulosity.
Stars are the focus of cluster images, so bright stars should be allowed to become larger than might be tolerated for images of galaxies or nebulae. After correcting color balance, enhance color to distinguish red giant stars from blue-white stars. If artificial sharp halos develop, select your brightest stars and apply a mild Gaussian blur of less than 1 pixel (Fig. 2). 40 The 100 Best Targets for Astrophotography Fig. 2. Open Cluster M37. Northeast is up. 5-in. 5 min –06° 24¢ – 10 × 20 arcmin for group Monoceros Reflection nebula NGC 2170, in the upper left of this image, is the brightest of several blue reflection and red emission nebulae in this region of the constellation Monoceros.
Unlike processing routines for nebulae and galaxies, you can allow curves and levels to brighten stars. More stars give a richer image. Many sharpening routines will enhance dimmer stars. Try to avoid moving the white point too far into the histogram, which may rob color from January: Mostly Nebulae 23 Fig. 7. Open Cluster M38 (lower left) with Open Cluster NGC 1907 (upper right).
