NGC3938, a spiral galaxy in Ursa Major, magnitude 10.4, diameter 5'.4. This image is a composite created from 61 images for a total integration time of 61 minutes. All images were corrected with dark frames and flats, then compositing, flatten background, unsharp mask (FFT, low-pass, hard), FFT filter (low-pass, mild) and finally a contrast stretch. Images were taken between 10:40 p.m. and 11:56 p.m. the evening of the 15th. All were taken using the f/6.3 focal reducer, for an effective f/ratio of f/4.
