About this image

Collected over 8 nights (01Feb - 15Mar).

Following stacking l noted the numerous nebular regions that NGC2403 is known for.

However I did note that in some cases when compared to Hubble and Euclid observations of NGC2403 the nebular regions are in fact densely populated star regions (see 'nebulous' patch in bottom righthand corner of image). It is the first time I've noted that BlurXTerminator deconvolution software can 'over-interpret' data, to be fair these regions were present prior to running the software! I have 70hr of narrowband still to process but require more OIII and SII data to complete NGC2403.
