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
My usual filter on the Hyperstar 4, on a C11, with an ASI 2600MC Pro CMOS camera, is a simple UV/IR cut filter. And this does the job admirably. But in my Bortle 4.5 zone I would like to filter … 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.
This is an image of the Triangulum Galaxy – Messier 33 – and it has been a little while in the making. This image is a composite of data taken with the Sky90 refractor and M26C OSC CCD, the Hyperstar … Continue reading
This is only 10 x 3-minute subs on the Hyperstar 4 with the C11 and 2600MC Pro CMOS OSC camera – but application of the star reducer program really makes it pop.
Russ Croman’s StarXterminator can be used to create a separate “stars only” layer in Photoshop. You can then process the stars only layer to greatly reduce the impact of the stars, and then reintroduce this layer back into the original … Continue reading
The biggest pain involved in getting the best out of a Hyperstar is getting the collimation sorted. As it was a full Moon last night I thought I would start from scratch (deliberately way out of collimation) and then see … Continue reading
