                        <content:encoded><![CDATA[<p>I just finished imaging this object recently.    I can probably get more data, but I want to move on.  </p>
<p><strong>NGC 4244</strong>, also known as <strong>Caldwell 26</strong>, is an edge-on loose <a title="Spiral galaxy" href="https://en.wikipedia.org/wiki/Spiral_galaxy">spiral galaxy</a> in the constellation <a title="Canes Venatici" href="https://en.wikipedia.org/wiki/Canes_Venatici">Canes Venatici</a>, and is part of the <a title="M94 Group" href="https://en.wikipedia.org/wiki/M94_Group">M94 Group</a> or Canes Venatici I Group, a <a title="Galaxy groups and clusters" href="https://en.wikipedia.org/wiki/Galaxy_groups_and_clusters">galaxy group</a> relatively close to the <a title="Local Group" href="https://en.wikipedia.org/wiki/Local_Group">Local Group</a> containing the <a title="Milky Way" href="https://en.wikipedia.org/wiki/Milky_Way">Milky Way</a>. In the sky, it is located near the yellow naked-eye star, <a title="Beta Canum Venaticorum" href="https://en.wikipedia.org/wiki/Beta_Canum_Venaticorum">Beta Canum Venaticorum</a>, but also near the <a title="Barred spiral galaxy" href="https://en.wikipedia.org/wiki/Barred_spiral_galaxy">barred spiral galaxy</a> <a title="NGC 4151" href="https://en.wikipedia.org/wiki/NGC_4151">NGC 4151</a> and <a title="Irregular galaxy" href="https://en.wikipedia.org/wiki/Irregular_galaxy">irregular galaxy</a> <a title="NGC 4214" href="https://en.wikipedia.org/wiki/NGC_4214">NGC 4214</a>.</p>
<p>With an apparent V-band <a class="mw-redirect" title="Apparent visual magnitude" href="https://en.wikipedia.org/wiki/Apparent_visual_magnitude">magnitude</a> of 10.18,<sup id="cite_ref-NED_3-1" class="reference"><a href="https://en.wikipedia.org/wiki/NGC_4244#cite_note-NED-3"><span class="cite-bracket"></span></a></sup> NGC 4244 lies approximately 4.3 <a title="Parsec" href="https://en.wikipedia.org/wiki/Parsec">megaparsecs</a><sup id="cite_ref-NED_3-2" class="reference"><a href="https://en.wikipedia.org/wiki/NGC_4244#cite_note-NED-3"><span class="cite-bracket"></span></a></sup> (14 million light years)<sup id="cite_ref-gemini_6-0" class="reference"><a href="https://en.wikipedia.org/wiki/NGC_4244#cite_note-gemini-6"><span class="cite-bracket"></span></a></sup> away. A <a title="Nuclear star cluster" href="https://en.wikipedia.org/wiki/Nuclear_star_cluster">nuclear star cluster</a> and halo is located near the centre of this galaxy.  (Wikipedia)    </p>
<p>What is a nuclear star cluster you might ask:</p>
<p>A <strong>nuclear star cluster</strong> (<strong>NSC</strong>) or <strong>compact stellar nucleus</strong> (sometimes called <strong>young stellar nucleus</strong>) is a <a title="Star cluster" href="https://en.wikipedia.org/wiki/Star_cluster">star cluster</a> with high density and high <a title="Luminosity" href="https://en.wikipedia.org/wiki/Luminosity">luminosity</a> near the <a class="mw-redirect" title="Barycenter" href="https://en.wikipedia.org/wiki/Barycenter">center of mass</a> of most galaxies.<sup id="cite_ref-1" class="reference"><a href="https://en.wikipedia.org/wiki/Nuclear_star_cluster#cite_note-1"><span class="cite-bracket"></span></a></sup></p>
<p>NSCs are the <a title="Central massive object" href="https://en.wikipedia.org/wiki/Central_massive_object">central massive objects</a> of fainter, low-mass galaxies where <a title="Supermassive black hole" href="https://en.wikipedia.org/wiki/Supermassive_black_hole">supermassive black holes</a> (SMBHs) are not present or are of negligible mass. In the most massive galaxies, NSCs are entirely absent. Some galaxies, including the <a title="Milky Way" href="https://en.wikipedia.org/wiki/Milky_Way">Milky Way</a>, are known to contain both a NSC and a SMBH of comparable mass.<sup id="cite_ref-nishiyama2012_2-0" class="reference"><a href="https://en.wikipedia.org/wiki/Nuclear_star_cluster#cite_note-nishiyama2012-2"><span class="cite-bracket"> </span></a></sup></p>
<p><sup id="cite_ref-nishiyama2012_2-0" class="reference"><a href="https://en.wikipedia.org/wiki/Nuclear_star_cluster#cite_note-nishiyama2012-2"><span class="cite-bracket">(wikipedia)</span></a></sup></p>
<p>I imaged this object with my TEC180 refractor with 0.9x flattener installed.   The Camera is a QHY600PH-M with Chroma RGB filters.   I've been playing around with doing just RGB instead of mostly luminance with a little RGB.    The RGB only has given me better colors but I know an L is must more efficient in photon capture, so it's all a tradeoff.    I wish we had more clear skies as I'm data starved.    I captured a total of 9.5 hours of exposures, each 8 minutes long using an extended well depth exposure mode on the camera.    </p>
