rdm<p>Today we have a mosaic of two images, both taken the same night by two <a href="https://aus.social/tags/Dwarf3" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Dwarf3</span></a> <a href="https://aus.social/tags/SmartTelescopes" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>SmartTelescopes</span></a> from the roof of the studio at the back of our house, where we left them running all night, with the help of a pair of 10Ah USB-C powerpacks.</p><p>I targeted The Cat's Paw Nebula (NGC6334), while <span class="h-card" translate="no"><a href="https://aus.social/@leece" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@<span>leece</span></a></span> targeted part of the nearby NGC6357. We both made sure to have the individual nebulae off-centre frame enough that we could get a slight overlap.</p><p>For both we have around 7 hours of exposure - 420ishx60s@80, both with the internal Ha/OIII filter.</p><p>We ran both images through the Dwarflab Stellar Studio to do a star removal, and recomposed both images with a star mask. Some final tuning in Snapseed, and then a manual combining of the two shots.</p><p>All up, about 2 hours actual effort, over three days.</p><p><a href="https://aus.social/tags/Astrophotography" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Astrophotography</span></a> <a href="https://aus.social/tags/Astrodon" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Astrodon</span></a> <a href="https://aus.social/tags/NGC6334" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>NGC6334</span></a> <a href="https://aus.social/tags/NGC6357" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>NGC6357</span></a> <a href="https://aus.social/tags/MosaicImage" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>MosaicImage</span></a> <a href="https://aus.social/tags/Nebula" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Nebula</span></a> <a href="https://aus.social/tags/Astronomy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Astronomy</span></a> <a href="https://aus.social/tags/Dwarflab" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Dwarflab</span></a> <a href="https://aus.social/tags/Snapseed" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Snapseed</span></a></p>
