Thank you, very appreciated!

Hi, my take on this iconic target. 6 hours in Lum, 2 each in RGB and 5 in Ha. I blended the Ha with the R and the Lum. Other details on Astrobin. Hope you like it. https://astrob.in/i2l1g6/C/

Re-shot the blue channel last night and did a full re-process. Much happier with the final image.

Thanks for the comments. I’m going to reprocess this, there’s an issue with the blue subs, and I’m going to try an HDR version to try and tame the main stars of the cluster.

One of my favourite targets each year. Went for a subtler approach to my last attempt where I felt the stars went quite technicolour. Happy with the NR in the background using John Rista's method and a slight de-emphasis on the stars with Adam Block's very clever method. 6 hours in L and 2 in each of RGB, processed minimally in PI - all shot from my back garden in Cyprus. Hope you like it - all criticisms and comments welcomed as always. https://astrob.in/9df1od/0/

Still for sale. Price negotiable. This will include full set of 1.25 filters.

The Iris Nebula. 18 hours in total over several nights. Processing in PI. I used John Rista's NR techniques and applied some slight deconvolution. I also de-emphasised the stars using the method detailed by Adam Block. I processed the nebula separately using Starnet in PI an deliberately didn't over saturate the stars. Finally I went back and slightly darkened the background. Hope you like it, comments and criticism welcomed. https://astrob.in/b6esyw/B/

You just select "No LNC".

Thanks, that's good info. I'll try it later on.

Yes, sorry I missed it off my workflow. Edited now.

You said you used mosaic/separate as the second step. You need to use register/match instead. I’m sure there’s an error in the light vortex workflow as I get the same geometry issue when I use seperate option. If you read Warren Keller’s book he used this method and it works every time. By the way, I also use APP for mosaic construction.

I'm looking for some advice. I have never successfully created a mosaic of M31 that I am happy with. For some reason I can never quite match the intensity or the colours across the panels which you can see from the image below ( the Lum is usually ok). I'm not so worried about the seams as I know I can sort that but I do need help with the rest please. This year I made sure to take each filter on the same night. there is approx 1.5 hours of 300s in each RGB panel (x4) although i lost a when sifting them, and the Lum has 3hours in each panel My work flow is: 1. PI - Crop the edges 2.

Thanks guys. I’ll give them a shout. I’m removing it from sale.

Hi. I think it needs more than bearings. It’ll need a complete overhaul and gears looking at. I wouldn’t be comfortable selling it as advertised but would let it go for £125 at buyers risk. If not, I’m going to send it to Moonlite to be repaired properly. Definitely needs someone e who knows what they’re doing.
