I acquired yesterday the third hydrogen panel of this area. I might add 2 more below, in landscape. We shall see how the weather plays. 2.5h each panel in 300s subs at unity gain. And some 30s exposures for the core. Camera is ASI1600MMC on the Canon 300 F4 L lens, cooled to -15C. And first successful try with the Astro Pixel Processor, though, the stacks were made with DSS. I just purchased APP and I didn't restack them.
I'm not sure if I should add more hydrogen data or move to oxygen and then LRGB. I still have time to decide until Feb-March.

It turns out I can not acquire more data until this challenge ends.
I present you therefore what I have until now. It's a 5 panels mosaic in Hydrogen alpha. 3 panels in portrait mode, at the top. And 2 in landscape mode, at the bottom. Each panel is made by 30-31 subs of 300s and for the Orion nebula core I have a few 15s subs.
All subs are taken with the ZWO ASI 1600 MMC, cooled to -15C, and 139gain. The lens is a Canon 300 F4 L with a lot of distortions caused by the IS element. Compared to the images I was taking on other targets until Orion rose enough, the focus was good since the beginning and remained ok during the nights.
Mount: AZ-EQ5. Guiding with a 200mm lens.
Software used: APT and PHD for acquisition; DSS, APP, Registar, StarTools and GIMP for processing.
I plan to acquire 4 more Ha panels in landscape mode to cover the same area to increase the SNR and then to move to O3 and LRGB. A lot of work this winter.

Thanks and clear skies,
While waiting for the main target to rise, sometimes I aimed the lens and camera to the Pleiades. The setup is Canon 300 F4 L and ASI1600MMC.
Camera cooled to -15C, 350x60s subs at unity gain. Lens wide open and IDAS-P2 filter.
And last year's shot with the DSLRs and the Tair lenses used as colour.
Perhaps they could have been better processed, this is the first try while waiting for one more panel on Orion. It's very difficult to remove the light pollution due to the IFN, perhaps this could have been done better too.
