  1. Think I'm shooting through a fair bit of high altitude whispy cloud. Hard to tell, but the subs aren't looking great. A bit brown and murky with splattery looking stars even though I'm focused properly. Went from 10pm - 3am green to all orange except for 3am now. Meh. Poured myself a glass of red for my efforts anyway, think I'll leave it running, hopefully get some clear skies or data worth keeping.
  2. Hey guys, just been shooting some b-roll for my astrophotography channel, second video. This time I'm going to be shooting M33 for the first time. Glad to have finished the Eastern Veil tbh, 4 nights of imaging since August it's nice to start imaging a new target, especially one I haven't imaged before. Still get a big buzz when I see new DSOs on the back of my DSLR! Looks quite clear tonight and no Moon until 1-2am so hopefully a few hours on it.
  3. This is really impressive! I can't believe I am faffing around with a DSLR unmodified and imaging for 16 hours to get an image with way less SNR than this. I need to buy myself my ASI294MC Pro !
  4. Thanks Alan. Was looking for a star cluster which will look sufficiently big to image in my fov but M13 isn't that big, probably not worth imaging with 430mm.
  5. Hi all, Is it okay to image star clusters when the Moon is out? I think I've read that you can do so, but is imaging them in moonlight affected by the moonlight as opposed to no Moon ?
  6. Think you've answered it for yourself then, the ASI294MC Pro with say, the STC Duo Narrowband filter looks like a great combination. I think I'm going to upgrade to this as it will be a nice introduction to dedicated cameras from a DSLR and I could then upgrade to Mono perhaps when I've mastered cooling, gain, darks etc. all of that stuff. Since August I have had 4 clear nights, two with great transparency and seeing but two not quite so much. And that's every single night since then. If it's clear and moonless that's all we have had. I think if you live where clear skies are the norm (South of France for instance) then I'd definitely invest in Mono as you'd just have so much more time to invest in a Mono system, no rushing, no frustration in that you haven't completed a sequence of imaging or collected all of the data from each filter etc. As OSC Cameras improve as well I just think they're going to get better and better, and these narrowband filters are improving all the time as well. The QHY268C looks terrific, is in development, and will be around £1,900.
  7. Jeeze. That's amazing. The best Eastern Veil Nebula I've ever seen. Wow. I definitely need to buy a dedicated astronomy camera. So this was imaged with an ASI1600MM Mono?
  8. I think if i was starting out again I'd probably go for a modded camera. But, and I may be wrong on this, there are pros to having an unmodded camera I think, which are; Sometimes, in quite a lot of photos I've seen from modified DSLRs, there tends to be too much red. I don't know if this is a problem with the the way that they are modified or because they are modified / letting too much Ha dominate, or whether its a processing problem which presents itself in modified DSLRs and means toning back on the 'over-red' is just harder to process. Star bloat seems to be a problem / more of a problem sometimes with modded images I've seen, and less so without modified DSLRs. Star colours seem better with unmodified DSLRs. Again, this could just be my perception and not exactly how things are. But with a modified DSLR you can record more structure in the Ha and discern more of it visually in a quite a substantially shorter time. And you can also use Ha filters with modded DSLRs. I think I'd be happy to forego any of the pros of an unmodified DSLR if starting again. But just one thing - there are plenty of targets which aren't dominated by Ha so a modded DSLR is definitely not essential. Over the last two years I've been imaging with an unmodified DSLR, and here are some images to give you an idea of what you can achieve with one. Having said that I've been happy learning about astrophotography over the last two years and imaging with my unmodified Canon80D... soon I'll hope to be buying myself a dedicated astronomy camera so I'm excited for that.

  9. Hi all, This is my longest astrophotography project to date. The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus. It constitutes the visible portions of the Cygnus Loop, a many portions of which have acquired their own individual names and catalogue identifiers. The source supernova was a star 20 times more massive than the Sun, which exploded around 8,000 years ago. The remnants have since expanded to cover an area of the sky roughly 3 degrees in diameter (about 6 times the diameter, or 36 times the area, of the full Moon). The distance to the nebula is not precisely known, but Far Ultraviolet Spectroscopic Explorer (FUSE) data supports a distance of about 1,470 light years. Integration: 15 hours, 50 minutes of total exposure time ISO 200 No Darks (Dithered) 200 Bias Frames 25 Flats Per Session Equipment: Telescope: William Optics Zenithstar 73 Mount: Sky-Watcher HEQ5 Pro Rowan Belt Mod Autoguiding Scope: Starwave 50mm Guidescope Autoguiding Camera: ZWO ASI 120MM Mini Camera: Canon 80D (unmodified) Software: PHD2 Guiding Astrophotography Tool Deepskystacker Adobe Photoshop Adobe Lightroom I've just started an Astrophotography channel as well so if you want to see the final session you can here...
  10. Good suggestion, thanks. Worth considering.
  11. Hi guys, I'm starting a youtube Astrophotography channel and need a name / brand for it. Wondered if you have any suggestions? Thanks! Joel
  12. Can't believe how quickly the full moon is coming around again. Feels like we've hardly had any new moon at all. I've had 4 moonless clear nights since the end of August and we're coming towards November. I think I'll definitely be upgrading to an OSC Camera now, I just simply would not have the time with our fickle skies to image and faff around with Mono, swapping filters, doing seperate flats etc. etc. with such limited clear nights. If I lived in the south of France where clear skies are in abundance Mono is for sure the best option but we don't tend to have that here - if it ain't cloud it's wind.
  13. The transparancy wasn't great here so I've packed up as well. But I think added to that a high veil of cloud set in too.
