Experimenting with some widefield H-alpha. Here's some previews of how the first test night turned out. Strong gradients with all the LP here. Samyang 14mm f/2.4 XP at f/3.5 on ASI294MM, ZWO filters.

Sh2-308 - Dolphin Head Nebula

25 x 900s (6.25hrs) H-alpha
59 x 900s (14.75hrs) Oxygen III

Cropped on the cluster

Quick test before the dew took over, monochrome broadband (about 2 hours total) of M13 from a pretty wide fov, MiniCat51 with ASI2600MM

work in progress, Vulcan Nebula, here is a preview of luminance channel collected so far #astrophotography #astronomy

No worries, no rush, astrometry.net solver does solve it: nova.astrometry.net/user_images/... so it should work since the bot uses it also.

First light with the miniCAM8M (IMX585 sensor), paired with the FMA180 Pro (f/4.5) for a compact mono imaging setup. Used a small cheap spectrometer to compare (just for fun) the included filters (XiMei) to a set of ZWO narrowbands. To me they look to be slightly better? #astronomy #astrophotography

Taking the full moon as an opportunity to collect some data on other targets. Might as well collect SII and OIII on this also?

IC405 & IC410 - 48 x 900s (12hr) H-alpha

Work in progress, still collecting data, Heart of the Heart Nebula, including Melotte 15. This is crop of a much wider FOV image.

71 x 900s Ha
86 x 900 SII
97 x 900 OIII

Third channel, stack of 30 frames x 900s each, SII on the Heart Nebula from last night. SII in this region is quite rewarding.

And now a quick stack of 25 frames x 900s each, OIII on the Heart Nebula last night.

#astrophotography #nebula #ic1805 #cassiopeia #monochrome

Quick stack of 16 frames x 900s each, h-alpha on the Heart Nebula last night.
