Still fighting DSS to stack my 46P subs, so made a time-lapse instead.
89 x 1min, taken on 27 Dec with Fuji x-T1 and Samyang 135mm. Size of frame is 2.2 x 1.7deg.
Have a much better quality avi file, but that's 214MB, so need to figure out how to convert it to MP4 in better quality (for this one I used youtube ?)
Two clear nights running to try out my new Samyang 135mm with the 428ex.
This is 24x300s processed in PI: DBEx2, MaskedStretch, HDRM + LHE.
I know this combination produces significant undersampling but that aside I am very pleased with the widefield capability now available with the 428ex.
Thank you for looking.
Been a lean few months what with dreadful weather then some clear nights but accompanied by a bright moon, its been challenging to get any imaging done. I also have a local issue with school playing field floodlights Mon-Fri that mean I can't really get any imaging done until they are turned off after 10:30pm - which on a work night really limits my imaging time - so a clear Saturday or Sunday night with little moon interference is a double win
Last Sunday was one of these nights - my original plan was to try and add to my Orion Barnards Loop Mosaic I started early December, but as I found out as I slewed to frame the outer reaches of Barnards loop I also framed the hedgerow trees to my south - Duh!! A quick re-think and as many fellow SGL imagers have been targeting the Rosette I slewed to that and kicked off APT. I will say that I am a bit frustrated with this image as I spent quite some time using a Bahtinov mask and the mask aid in APT plus the focus aid to get a sharp focus but the resultant image is a bit soft - perhaps the seeing and/or the fairly course resolution of 6.08"/pixel contributed to the overall 'softness'. Perhaps it was a night for a higher F number, but I have used F2 successfully for previous images.
Anyway its a 3.5hr image, using my Samyang 135mm at F2 with ASI1600MC at unity gain mounted on AZEQ6GT - no guiding used
Baader Filters used 40 Ha7nm 90s 120 Lum 30s 60 Red 30s 60 Green 30s 60 Blue 30s I used DSS to stack with Flats for each filter plus Darks and Bias, Used Registar to align and create the RGB merge then into PS. I used the colour preserving Arcsinh stretch as outlined in this thread, thank you @sharkmelley for creating this PS version - first time I used it and I am pleased with the result v's a 'normal curves stretch. I also applied AstroFlat Pro to deal with gradients and a bit of NIK to take some noise out of the image and HLVG to remove green cast. The Ha was added as per Olly's method in the Red channel with a lighten blend - I did also mix about 15% into Lum that helped give a deeper red - given my lack of exposure I had to do something to get a bit of depth to the Rosette reds.. Its a different viewpoint if you like from the excellent high res close up images of the Rosette posted on the forum in recent weeks.
I am considering changing back to my 106 APO to get some higher resolution imaging under my belt but the Samyang 'style' and relative ease of capture with no guiding required is growing on me.
Thanks for looking and as usual any pointers to help improve my image let me know,
Just a quick query regarding this, and to ask if anyone out there has had any success in getting a D3300 to work with Astroart. I've downloaded the Nikon plugin from the website, and the blurb suggests that it might work. I've tried setting the plugin up as a Nikon camera, selecting "other" from the drop down list but get the message:
Cannot find other md3 DLLs I have also tried the D5300 setup on the off chance, but got:
Cannot open md3 DLL - Verify that Microsoft Visual Studio redistributables are installed I have installed MS Visual Studio but that does not seem to have helped. I've checked my file system and the only md3 file I can find is called Type0011.md3, and is in the Astroart6 directory of my computer.
Anyone out there have any ideas?
For reference, the reason I want this is to set up a script to automate slewing and imaging of a set of variable stars. If there is any other software out there that will support an HEQ5 mount and Nikon D3300 I'd be interested to hear about that also.
