Hi all,
Another go at the Dark Tower now that it’s better placed for max data acquisition.
Went a slightly different route with Ha and RGB stars for an experiment.
19hrs Ha (71x1000s) and 3hrs RGB stars taken with 2600MM/Chroma RGB, 3nm Ha filters GSO CF RC6 on an AM5n.
I liked the outcome - the area is as dramatic (apocalyptic!) as ever!
One of my friends said it looked like a dark horseman riding out of the cosmic mists - as an apt an interpretation as any I suppose?
WOW, that's done with the 6" GSO, no image magnification through a powermate or anything?
I believe a Barlow will lose quality (and light), not so much the Powermates (I haven't really tried my 5 times yet, once on the moon with an 80mm Megrez SD).
I didn't pay attention to the telescope before, more the camera.
The longer I stare the more incredible the image gets!
The more I look at it Doug the clearer the Horse awesome image mate, well done.

Thanks for all the kind comments Gents
Leo - no added glass, just the 6"RC @ FL=1370mm
I'd be very interested in seeing if I can get something 1000th of the quality and detail you've gotten. I don't have a mono camera or HA filters and the camera I do have other than the Nikon D810 full frame is a lower spec Player one Neptune with the ASI178 coluor sensor. Plus that level of integration would be nigh on impossible with my temporary set up (big hole dug for pier where my mount normally goes, bad weather and bad health (migraines) have made what should be 1 days work into several months and still not done). The prepared hole is currently full of water, maybe a floatie at the base of the heavy pier (1/4" or 5/16 wall thickness on tube with 1/2"plate top and bottom but if would bob up and down.and be useless. I do have a semi prepared area beside the hole as long as the hole is covered so I don't stumble down in the dark (I have 3/4 inch rebar hammered into the clay at 45-60 degree angles in each corner and crossing over in the centre of the hole. I've yet to weld up a jig to hold my 16mm stainless threaded rod to set in concrete but I may up that to 20mm threaded rod, the holes in the base are large enough. I've put a couple of bags of concrete powder in the base to stop the water ruining the concrete and stop the clay sucking the moisture out. This should prevent movement and slip of clay on a sloping yard . However, I'd still love to try if the weather and migraines clear for a few nights I'd be keen to see if I can get anything. I need to check the collimation on the RC 8 and hope it's not too far out if at all because I'm not competent to collmate the unit.
Even if I could get 6 hours integrstion time I'd bee keen on seeing what I could get and wouldn't expect it to be anything like yours.
The other issue is the street light across the road. I'm seriously considering driving some pipes into the ground and wrapping it in either builders plastic (black) or maybe even shade cloth to see if it subdues the ambient LED street light.
Give it a crack Leo - your 8” RC will get in a little closer.
I’m lucky that I have my set up in a little ‘pool pump shed’ observatory which allows me to get up and running easily.
Integration time - I’m always greedy, trying to get as much as possible!
1000s subs is probably pushing the law of diminishing returns I think!!

awesome image mate, well done.
