<p>Greetings everyone! I am quite new here at CN, mainly as a logged user. Have been doing planetary astrophotography for nearly a year now and recently upgraded my set to a Celestron Nexstar SLT 130 Newt. Last september, tried a few days chasing Neptune, and achieved 2 times. Both tries were with a Svbony sv105, a super entry level chinese brand (which I found Very cost-effective, since the Brazilian currency makes everything we spend um USD Very expensive). The first record ended up as a bluish teardrop shape planet... I checked the collimation and it was awful. The second time, the collimation was ok (I think) and the final image was far better, but still I noticed some offset on it. (Attached image)&nbsp;</p>
<p>This second register I accomplished with only 40% of the besta of 200 frames 125ms each, for the planet os too faint to work with smaller exposures.&nbsp;</p>
