NGC1333

This is a re-shoot of NGC1333. This image has been a nemesis of mine with something going wrong on every attempt. The first time my scope have a problem with pinched optics. The second time out I did not collect enough data and the result was quite noisy.This time around I made the subs a little too short and had some pattern noise to deal with, but after processing it seems to be a reasonable image although I ended up applying too much blurring to the cloud in order to remove the pattern noise. Hopefully taking a large number of bias frames will help with this. If a better quality bias frame helps I'll repost the image. NGC1333 is a reflection nebula in Perseus belonging to the Perseus molecular cloud.

Object NGC 1333  Object RA 03:29:12 Dec 31:21:55 Date November 23, 2019 Exposure 165 minutes (33 X 5 minutes)  ISO 800 Camera Canon 60Da DSLR Optics Prime focus of a 120 mm SkyWatcher f/7 Esprit APO refractor Location SCO, St. Croix, Nova Scotia Processing This image was processed entirely in Images Plus. Statistical filter applied to reduce noise before stretching. Masked stretching and split star processing used to enhance the image. The background was left bright during the stretch and lowered by subtracting a constant from the image with an inverse luminance mask applied. Masked noise reduction using a frequency domain lowpass filter applied between each stretch and the saturation was also boosted. Image binned by two. Final sharpening applied.
