I just found another 6-hours of 40-minute subs of M31 taken with the Sky90 array, and I added this to the earlier composite. You can see the result above and it is virtually no different from the previous result. I … Continue reading
This image of the Rosette nebula is a composite using data from the 200mm lenses with ASI 2600MC Pro CMOS camera and Optolong filter, together with Hyperstar 4 data using an ASI 2600MC Pro CMOS camera and a UV/IR cut … Continue reading
I sent a friend a low-res version of M31 and they asked if they could have the hi-res version to print out and put on their wall. Now it gets embarrassing – can’t find the hi-res version anywhere. So I … Continue reading
Absolutely all the data I have on the Triangulum Galaxy.
M33 – The Triangulum galaxy. Only 38 x 4-minute subs on the Hyperstar 4 on a Celestron Nexstar 11 GPS with an ASI 2600MC Pro CMOS camera.
This is only 39 x 4-minute subs taken using the Hyperstar 4 on the Celestron Nexstar 11 GPS SCT with an ASI 2600MC Pro CMOS camera.
As mentioned earlier, I did try the Optolong L-Extreme filter out on the Hyperstar 4 (on the Gamma Cass nebula) and the result was – no improvement as far as I could see. So as expected, these filters are not … Continue reading

This image is a composite of Sky90 and Hyperstar 4 data only.
This is the central region of the Rosette nebula. This is a composite image created using RegiStar and comprises original Hyperstar, Sky90 and Hyperstar 4 data exceeding 15-hours of total exposure time.
