Hi dear friends of Astrobin. This is my first topic. I have a triplet telescope (115mm) and a ZWO ASI 1600 camera. My data is always good, but my filter blue, generate a large stars. (please look my images) My questions are: Is my telescope badly correct? Is my image scale the problem? (maybe big pixels help me?) Ps.: Excuse my little english. Hugs from Brazil.

Hi Maicon! Maybe your target object has been quite low on the horizon? Low means under 35-40 degrees. I do own two APO triplets and in my experience different star sizes are happening even more the further down the object is. |

Hi Michael. Thanks for your answer. I saw your gallery and i think that the size pixel could be my "problem". Your câmeras have more than 5 microns in pixel size. Another test. Look for any refractor telescope in astrobin, with asi1600 cameras. Almost all, have strange blue stars. Could that be it? Hugs Michael. Maicon Germiniani |

Hi Roberto. I already use The Astronomik L3 in my setup. This filter Cut more blue spectre than The LPS-P2. I use The L3 in front of all gear. (In Flattener) Maicon Germiniani |
