Zefeo konstelazioan,
Sh2-140, Sh2-145 eta Sh2-150 distira ahuleko nebulosak dira 4
graduko eremuaren barruan.
Prozesatu dudan argazkirik zailenetakoa da, kontraste baxuko
irudia lortuz horrela elkar nahasten diren nebulosa ahul gorri,
marroi eta urdinak nabarmenduz irudi prozesamenduan, Sh2-145
nebulosan gertatzen den bezala.
In the constellation Cepheus,
Sh2-140, Sh2-145 and Sh2-150 are faint nebulae within almost 4
degree apparent field. This image is one of most difficult field
that I ever processed to getting a low contrast image to show
all those fine structures, paying attention to very faint red,
brown and blue nebulas mixed all together as in Sh2-145.
