This is a 4 panel mosaic. Data collection started in December 2016 and ended in January 2018. Total integration time is 50.3 hours.

It is sort of an HDR image, since SH2-240, the Spaghetti nebula, is much fainter than IC 405 and IC 410. Consequently, more than 40 hours of integration time have been dedicated to this quarter of the mosaic.

Two parts have been shown here as separate images before:
IC 405 and IC 410 Widefield
Spaghetti Nebula, Simeis 147, SH2-240

All in all I had severe (and unsolved) problems when creating that mosaic: While PI can easily handle the distortion of a 2 panel mosaic with a FL of 135mm, it could not do the same with a 4 panel mosaic. Maybe I will have to look for a different software for that task.

Anyways, I hope you enjoy this pic despite of it.
