Another complete reprocess. This time it is the Heart nebula, captured on the Sky90/M26C MiniWASP array. A two frame mosaic totalling 39 x 20-minute subs (13 hours).
A complete reprocess of Sky90/M26C MiniWASP data for Y Tauri. This is 30 x 10-minute subs.
39-Delta Persei (SAO39053) is a VERY blue star as you can see. Spectral type B5III SB. This is 72 x 450-second subs (9 hours) on the Sky90 array using the M26C OSC CCDs.
This is all the data I have from the HSIII and 814C plus the Sky90s and M26Cs. This will be in excess of 8-hours of data.
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
All the data I have all put together to give this image of the Witch’s Broom nebula.
This image of the Veil nebula in Cygnus incorporates all the data I have on the object. So this image includes Hyperstar III on the C11 data, Sky90 (2-frame mosaic including narrowband) data, and the Canon 200mm lenses with the … 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
