Laurin Dave Posted February 15 Share Posted February 15 A multi panel (15plus) mosaic of dusty Taurus spanning about 25 by 18 degrees and including the Hyades, Pleiades, California Nebula, Northern Trifid (to the left of California) IC348, NGC1333, many LDN, LBN and Vdb objects plus Mars as it was 22 Dec22 and Comet 2022/E3 as it was 13 Feb23. Data acquired between late November 2022 and 13Feb2023 using primarily a Samyang135ASI2600mc, with 3 plus hrs on most panels and more over the Hyades, Pleiades and IC348 area, additional luminance data was captured through an Askar200QHY600 combo and applied over lower signal areas at top left and bottom right,. Ha data was also captured over the California Nebula through a GT71QHY600 combo. Processed in Pixinsight and Photoshop using PIs Normalise Scale Gradient, Mosaic by Co-ordinates and Photometric Merge Mosaic to align and merge the panels, Stretched initially in PI using ArcSinh, GHS and HT, then stars removed with Russ Croman's Star Exterminator, further stretching of Starless image in Pi, then colour enhancement, Ha and Lum blending in Photoshop before replacing the stars in Photoshop using Screen mode. Final levels and Noise Exterminator in PS. then resized to 12 arc sec/pp in PI. Thanks for looking Dave 43 Link to comment Share on other sites More sharing options...

Paul M Posted February 16 Share Posted February 16 So much going on! My favorite area is the Pleiades and their interaction with the dust and gas. Its seems to be only recently that advances in cameras and processing techniques have allowed the true nature of that environment to be made visible. Your image shows the reason that the nebulosity round Merope fades from blue to dusty brown colour in more regular Pleiades images. It just looks like the Pleiades are a bioluminous marine animal swimming through dirty brown water! 1 Link to comment Share on other sites More sharing options...
gorann Posted February 16 Share Posted February 16 Amazing piece of work Dave! Great overview of all the dust around in this region. The comet if of cause a bonus and a kind of unique time stamp. 1 Link to comment Share on other sites More sharing options...

ollypenrice Posted February 26 Share Posted February 26 This is tremendous. What a vista. I've always thought it ironic that, the shorter the focal length of an instrument, the better it is for making mosaics. I was never tempted by mosaics when using long FLs but always want to use widefield setups to go wider still. Also, the apparent resolution improves to the point at which you'd hardly notice the difference between, say, a Samyang image and a very-multi-panel telescopic one. This is gorgeous though, personally, I'd bring down the red saturation in the California. Olly Link to comment Share on other sites More sharing options...

Short fast focal lengths combined with small pixels and the latest tools, Normalise Scale Gradient (you probably don't need this, but us Bortle4/5 dwellers do) and Russ Croman's BXT, SXT and NXT work very well., and yes its a bit too red!
