Astro Waves

it feels like theres more to think about than when shooting a DSO! hah. I would just be using my Redcat 51 to shoot with.

ahhhh I see. I'll be using the ASI294mc-pro as I'm pretty sure you can do video on that. Would you recommend any software to process the video? Are there any differences in stacking video frames and imaging frames?

I wanna have a proper go at shooting the moon rather than just taking a single image and working on that. Is it necessary to take calibration frames? Cheers

I bet they loved it! when you can see someone has a passion about something people will be interested regardless. I bet it was a good 3 minutes.

Personally I'd say go for the Star Adventurer Pro 2i, if you end up wanting to get into doing some deep sky imaging which I think may happen once you realise how awesome it is to shoot space I don't think the mini would be able to handle the weight of a larger 135/200mm lens. In terms or targets 14mm is pretty wide, you could just point it at the sky in general and get some interesting shots to practice with but something like Barnard's loop would be a good one thats very much coming into full view soon.

Hi all, Think I might need to get a bit more of a decent/reliable dew heater and was wandering if anyone has any recommendations? Had a look on the FLO site but they seem to be all out at the moment. Not exactly in a major rush but something I do need to sort out. Cheers

Every so often when I'm just pottering around I always go to myself "it would be ace to live in the artic circle when it gets dark for a few months, then you could just go out and shoot any time".

bloody lovely that is! 8 clear nights in a row? I wouldn't know what to do with myself if that happened over here, haha, I'm lucky to get a few hours at most!

I really like it, let the artist in you loose!

nice, thanks for the help, definitely given me lots to think about. On a side note I'm looking into CCD cameras and was eyeing up the ASI183-MC and noticed in your sig that you use the MM version, how do you find the amount glow with this camera? I feel like I'm spending for ever trying to read about what cameras to match with the redcat 51 and the 183 seems to be a good fit, don't think I get enough sky time to go down the mono route yet and would probably be easier and more consistent when I know I can frame much easier over multi night shoots using a go-to mount when that time comes.

Next time I get out there I'll give it a go with making the dithering more frequent and se if that makes a difference. Is banding something that in ingrained in the actual camera or is it something that changes each time you shoot if you get my drift? tried to make a pun out of that but hopefully it makes sense, haha. I had a funny image of putting the entire set up my tiny fridge and my partner coming home and opening going "what the heck are you doing?" I've never really been sure of how many of each darks, flats and biases to take, is it kinda like the more the merrier?

Ta very much. I know, I know need more darks and I never take enough of them as it usually gets on being too late/being too tired to have the patience to wait for them to tick over even though I should do. I have been looking a cooled camera as this would definitely help so I could do them any time. Had thought about upgrading the mount first to a go-to but now I can plate solve with ASIAIR pretty quickly its really to too bad at all. So I do set the ASIAIR to dither every 5 images I think but is it worth it doing it more frequently than that? Thanks

Finally had a super clear night here in Edinburgh last night. Got to my usual shooting spot, did the standard setup which is getting much more swift including PA and finding target now I gots the ASIAIR Pro (which I'm loving for its simplicity and ease of use). Also received the Optolong L-extreme so thought I would give it a go. I feel like I'm getting there more slowly than I'd like with the imaging results and everything that comes with it etc.......but I'll tell you whats not great, when you forget to turn on your dew heater and also to charge your phone thats running ASIAIR app but regardless I had a nice time. The is the first edit I've tried for this image and pretty happy with it I'd say, definitely more on the orange/red side but I like it so stuck with it and sacrificed some whispy detail for a smoother image. I do have a couple questions, I'm shooting on DSLR and used a pretty low ISO of 800 but I feel the amount of noise I'm getting in the image is pretty darn high as you can see from the results below. I only got about 2 hours integration time but would more time mean a smoother final result? and also the second pic is of the stacked data form Siril I've found since I've started guiding and being able to take longer exposures that I'm getting these consistent lines when shooting, any one know what they are/if there's anything I can do to get rid of them via processing? Any comments or critiques more than welcome. Edinburgh - Bortle 7 - Redcat 51, Canon 750D Mod, iOptron Skyguider Pro, ASI120mm Guide, Optolong L-extreme, ASIAIR Lights - x46 180 seconds Darks - x7 180 seconds Flats - x25 1/40 Seconds Biases - x25 1/4000 second

Thanks for you input, much appreciated. I think unless I'm spending closer to big bucks amp glow seems to be more or less on issue from what I've been reading, but if it calibrates out then I'm fine with that. Last time I shot on my Canon 750D there was some horrific banding going on so sadly I couldn't push the processing as far as I wanted as I struggled to get rid of it, wasn't too much as a problem.......as the image was out of focus! haha (see image below). Being able to take dark frames off the scope would be so nice as I have no garden and use a friends allotment so the nights can get pretty dam chilly especially when you only have a shed to sit in. I always get a bit of itchy feet when I have to wait around for darks to be done (and I always have early starts in the morning which don't help). More detail sounds good to me. Not being doing the hobby too long but definitely feel like I'm turning into a bit of a galaxy hunter. The camera would be for the Redcat 51, I would like to up grade the scope at some point get about another 200mm on the go but no idea when I can do that as then I'd be looking into go-to mount territory rather than my portable set up. Well....funny you should mention the ASI 183 as there is one going on the 'For Sale' section in here as well. Not sure I fully understand the Astronomy tools calculator, what is the colour bar at the bottom representing? There's a pretty decent/significant crop factor when using ASI183 which is good as well. I've popped in a screen shot from the calculator so you can have a quick look but I'm guessing my current set up would suit the 183 more? Cheers
