Thanks Magnus, definitely think I'll give it a go again. Just used the star trails function in Sequator to get the effect and then layered the last image over again as a luminance layer.

Thanks Paul, there were loads of people up on the Tor. Just added a time-lapse composite for a bit of fun.

Thanks for the positive comment. Yeah, I did try but pulling down the highlights, just made the moon grey. I do have a shorter exposure of the moon at this focal length that I considered blending but thought I'd stick to the authentic and go with the single exposure. One of the disadvantages of the 6D and its age is the lack of dynamic range.

I popped out on Friday to capture the moon over Glastonbury Tor. It was rather warm and hazy, the moon had a lovely red hue to it that dissipated to purpleish, probably some Saharan dust in the atmosphere. Unfortunately this also meant that it was difficult to capture a sharp image. In-between swatting mosquitoes I managed to capture a few images. Taken with my Canon 6D and Sigma 150-600mm. The first image (Wide) was at 150mm f/6.3, ISO800 and 5 seconds. The second (Close) was at 600m f/6.3, ISO800 and 1/6th of a second. I was just over 5 miles from the Tor.

Great feel of depth in this one. Nice capture.

Here's a better colour balanced version but I fear it may have gone a bit more on the garish side. Bin2 and upscaled this time.

Many thanks @maw lod qan.

It's a blend for me @old_eyes. Prefer the inner and mid of the 2nd image but the outer dust of the first image. Lovely details in the centre though a well controlled white point, would a bit of highlight reduction draw out more detail?

Thanks Adrian. Pretty pleased with this considering the short integration time, the data was great though so seeing must have been good. Just need to work out how to make the stars pop more in my process, can't seem to fathom a way where they don't get blown out or a bit lost in the mix. Thanks for the comment Adam. It seems like a perfectly acceptable camera to me and keeps the budget managed as 1.25" filters work well. I think it pairs well with the mid to longer focal lengths too (c1450mm with the EHD8 and reducer). With all the matched calibration frames the data was a pleasure to work with. The double fans on the GT version easily keep the temp down as well, I could probably go cooler than -10c but not sure there would be any added benefit. Thanks Roy and Sunshine. It's one of those targets you have to try once if it's available to you!

This is my 2nd mono image using the ASI1600GT and ZWO Ha, OIII filters with the Baader SII filter and my first ever of this target. Taken with my Celestron EdgeHD8 and the 0.7x focal reducer. M16 was at about 24 degrees dropping to 20 above my neighbours roof. Imaged over three nights last week with little to no moon and just enough astro darkness. Each filter was about 2hrs of integration so 6hrs in total. Processed in Siril, StarnetV2, Topaz and Gimp. Using the Py-Astro Plug-in within GIMP I binned the image X3. C & C welcome.

Up to around 2hrs for me here in Somerset.

It is indeed my first. I've used the L-eXtreme and tried the false Hubble in the past with my OSC camera. This image was a number of firsts, first Mono-Narrowband and first with an OAG. I'm sure in time I will refine my mono imaging processing skills in time, OSC is a breeze by comparison!

The more I look at the above image the worse it seems to my eyes, I think I tried pushing the data too far. So I have done a reprocess. I think this is much better.

Hi all. I recently purchased a 2nd hand ASI1600GT to have a go at mono imaging. This is my first image, an SHO of the Tulip nebula using the ZWO 1.25 Ha and OIII and a Baader SII (big halos on this filter). About 4.5hrs on each filter with 5min exposures. Taken with the Redcat51 and processed with Siril, Gimp, Starnet & Topaz. The stars were really tricky so I'm not overly happy with them, the colours seemed to shift on each filter so had to spend some time in GIMP with the transformation tool to align them again. As always I welcome any comments and guidance.

Lovely images and compositions. The foreground quality looks great, were these with the 6D? What settings did you use and how dark was it, asking for a friend... ?

Thought it would be a good start as an intro into Mono. Bought locally with some 1.25 RGB Lum filters and an OAG for a reasonable price, I like the double fans especially in this heat, they don't work very hard at all. That looks fantastic! A nice investment meaning a much quicker set up time. Certainly think your RC will look good atop that, the Redcat looks a little lost, can you piggyback the Redcat on your RC?

+1 for the HOO image. I prefer the contrast and the colour separation. A great set of examples though Adrian, I now have and ASI1600GT so will be experimenting soon. I have some nice data on the Tulip with the Redcat but haven't got round to processing yet. I need some time to get my head around the mono narrowband process.

Thank you. I did it just to see how they turned out. I hypertuned the AVX myself a few weeks back so a bit of a test and experiment. 5 minutes would be my normal sub length with the l-ex. Certainly saw that some of the Ha was over exposed following the stack.

Thanks old eyes. Agree on the focus, I haven't rigged an auto focus on this set up yet and was too lazy to stay up and tweak throughout the night!

Taken with my Samyang 135mm Cine lens at about F3 and the 2600mc on my AVX mount. Included the L-eXtreme as the moon was about and unfortunately that changed my back-focus a bit so some eggy stars are present. I also pushed the exposures to 10 minutes and took around 9hrs worth. Processed in Siril, StarnetV2, Gimp and Topaz.

I've been playing with a set up for the Samyang 135mm, I have the cine version. Here's my first effort with the new rig configuration. I need to sort out an aperture mask rather than stopping down about one step. Have some squiffy stars in one corner but pretty pleased with this considering it's been taken over the last week with no astro dark, a fair chunk of moon, no filters and all manual focus. 9.5hrs in 5min subs on the AVX with the 2600MC pro. Processed in Siril, GIMP and Topaz. If viewed on a calibrated lower backlit monitor some of the subtle Ha is more visible.

That's a stunner.

Wonderful image Paul.

I am Groot!

Nice work for a short integration Peter. Looks like you picked up a slow moving object in the nose of the Horse. Any thoughts on what it may be?
