Live Stacking with Starlight Live
This time I tried to do EAA with Orion 10" Newtonian in order to compare performance of f4.5 and f1.9 optics. The answer is that f4.5 is fine for bright objects, but results with faint ones (like Cocoon Nebula) is not that good. The night was a bit hazy which likely compounded the issue. Hyperstar is probably the best choice.

![](javascript:display_picture('eaa/6/NGC457_2017.10.21_02.29.01.png','NGC457 with Orion 10" Newtonian and Ultrastar Color.',event)) | [2017-10-21 02:29:01] NGC457 with Orion 10" Newtonian and Ultrastar Color. FOrgot to switch to non-linear scaling and the stars are overexposed. Oh, well, it was half past 2am :-). |
![](javascript:display_picture('eaa/6/M42_2017.10.21_02.54.34.png','M42 with Orion 10" Newtonian and Ultrastar Color.',event)) | [2017-10-21 02:54:34] M42 with Orion 10" Newtonian and Ultrastar Color. The image is a bit out off focus, probably due to cooling of OTA. |
