This hobby can be so frustrating, it has been weeks since I have had the observatory open. In fact it was the 28th October since the dome shutter was rolled back for some photon capture.
My intended target was Sh2-157 The Lobster Claw Nebula, where my aim was to complete my longest imaging capture 24 hours total integration time using Narrowband filters. Narrowband filters are tuned to specific wavelengths of light emitted by Hydrogen, Sulphur & Oxygen and aiming for 4-10-10 hours respectively to create a Hubble palette colour image. One dismal failure later in respect to the weather that is, has left me with what was the initial capture of 1hr of Ha and 1.5 hours of Oiii and just 36 mins of S2 on the night of the 28th.
Patiently waiting now for weeks to further and complete the project. With more rubbish weather forecast over the next week I thought I would have a quick process to see what I have. I am not disappointed with the limited data captured and I guess It will have to wait now as there are winter targets I want to image and of course Comet 2021 A1 Leonard has brightened to becoming a serious contender for comet of the year. Agggggggggggggghhhhhhhhhhhhhh so frustrating.
