This is a multi night integration of the Rho Ophiuchi Cloud Complex from my Bortle 4 backyard in Wellington, New Zealand. It builds on my previous 51 minute exposure uploaded to my account a little while back. The gear I used was my second hand SMC Super Takumar 200mm f/4 (Stopped down to f/5.6 for sharpness), A DIY Modded (LPF2 removed) Canon EOS 6D, and Sky-Watcher Star Adventurer (Plus dew warmer, dummy battery, etc).

Since my Sky-Watcher Star Adventurer is not a GO-TO mount, i had to manually align the frame by pointing it in the region of Antares, taking an exposure, and comparing it to one from a previous night, i then manually aligned it (to the best of my ability) with the previous nights image! Also, the faint red nebulosity in the bottom right area was a pain to try and keep while also being able to use background extraction, GraXpert's AI background extraction seemed to want to remove it, to combat this, I used RBF mode in GraXpert and manually set the points in a way that avoided nuking the colour, while also removing the slight gradient I had.

This was processed in Siril, GraXpert, and GIMP. I also used SiriLic to stack the multiple nights of exposure together

Image Details:
Night 1: 51x 60" Lights | ISO 1600 | f/5.6 (Only got a short imaging time due to lens fog as a result of not yet having a dew heater, which arrived a few days later)
Night 2: 208x 60" Lights | ISO 1600 | f/5.6 (Stopped imaging around midnight due to moonrise)
Night 3: 108x 90" Lights | ISO 1600 | f/5.6 (Stopped imaging around 1am due to target going behind trees)

Processing details:
Stacked in Siril with SiriLic, with darks, flats, and biases (taken on each night). SPCC run in Siril, then moved into GraXpert for: Crop, Background extraction (RBF mode as mentioned prior), Deconvolution, and Denoise. Then taken back into Siril, Starnet++ (with 2x upsample enabled) run to generate starless image/starmask, starless image then stretched with GHS, and starmask stretched with GHS on modified arcsinh mode. Both then taken into GIMP, recombined with a screen blend and general post processing applied (ever so slight curve, saturation, unsharp mask, etc).
