Abell 35 - Work in Progress
I wouldn't mind some thoughts on where I am going with this one. I am collecting data on the Abell 35 PN which is very faint at the best of times. Some information even suggests that it is not a PN but that doesn't change the fact that it is there and I am imaging it. Depending on the source of information it is somewhere between mag 12 and 13 with a diameter of about 10'.
I am well on the way to collecting the Ha and OIII subs that I need. My target for each channel is to collect 30 x 30 minute sub each. I am going to need the extra data to try and pull out the information from the background and I will probably also collect some RGB data as well for the star field.
The thing that I am pondering is whether to bother with collecting photons for SII. I have attached a screen shot of the Pixinsight desktop with one of each of the Ha, OIII and SII subs open so that you can see how relatively faint the SII data is. Using the readout tool in PI for the SII sub, it is showing background ADUs in the order of 350 with the strongest signal in the actual object itself being around 430 ADU and much of it barely above the background noise.
So, my question to my learned collegues on this forum is - would you bother with the SII data collection or is it likely to be swamped by the the other signal anyway?. I would be interested to know what others think on this one.
