webcubus<p>UPDATE: There is an issue with the filter wheel where it leaves the IR LED (used to confirm filter position I believe) on. This effectively created a light leak on every sub/flat/dark/bias. ToupTek has a firmware update that fixes the issue and I can confirm that my flats look drastically different after the update. I think I'm going to have to toss all of the frames I've captured so far, but I'll report back after imaging tonight.</p><p>Hello astro friends! I could use your help with some troubleshooting. I just got a new ToupTek ATR585M mono camera and I'm unable to get my flats to work properly. Without flats, I can faintly see the dust and with flats, they show up very prominently. I have tried a bunch of different ADUs. I wrote up a blog post to show the issue because the flat overlay is the best way to demonstrate the issue. Thoughts?!</p><p><a href="https://blog.briangweber.com/mono-troubleshooting/" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">blog.briangweber.com/mono-trou</span><span class="invisible">bleshooting/</span></a> </p><p><a href="https://astrodon.social/tags/astrophotography" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>astrophotography</span></a> <a href="https://astrodon.social/tags/photography" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>photography</span></a> <a href="https://astrodon.social/tags/gear" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>gear</span></a> <a href="https://astrodon.social/tags/monochrome" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>monochrome</span></a> <a href="https://astrodon.social/tags/touptek" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>touptek</span></a></p>
