Another try in the latter stages of this year’s galaxy season where the weather has been so awful. Aiming for some good resolution and brightness using the 268C and a fast Newtonian.

This is another experiment on the feasibility of using an F12 scope for deep sky imaging. I have deliberately chosen an object close to the zenith which should remain visible for some time with the aim of completing a multi-night image before the end of galaxy season. The altitude will decline as we enter the month of June so the next two…

This evening was unexpectedly clear though with a thin layer of high, semi-tramsparent cloud which affected guiding and visibility. Around half the gathered frames were discarded. The clouds got thicker around 1 am so I closed the observatory roof and left the calibration frames for the morning. As has been the case recently, calibration frames have been very problematic but I did finally resolve two outstanding issues:

28th April 2023 I recently acquired a more capable processing PC which has opened the door to re-processing of lots of old data which was languishing untouched due to the unreasonable length of time required for the old PC to run Pixinsight. Nine months after the initial acquisition, the…

In spite of the pretty poor weather, galaxy season is still underway. I’m really happy with the detail in M108 and the central star in M97. The Antlia RGB filter is proving challenging at the processing stage as some very unusual reflections are apparent. This might also be light leaks in the flats (more likely, in fact). To be investigated.

An unexpected clear couple of hours gave me the chance to check the recalibration of backlash on the EQ6R Pro which now seems to work nicely having guided at around 0.7"/px consistently last night. By way of as test I shot some 5 minute frames on M64 followed by some flats and flat darks in accordance with my new calibration frames…
