  1. Hello everyone, I posted here probably about a week ago, with frustrations and troubles on a certain target, and just general frustrations a beginner goes through. Anyhow, with help from the community, and an extra thanks to @alacant for the extra help and advise with StarTools, I've finally produced an image I am actually proud of. Although its framed up the same as my last one, non of the same data was used, totally new data. I was fed up with my last image, and past images I've posted here, looking more like cartoon drawings full of noise rather than real images. Although it's still not perfect, its the closest to real I've gotten. It was taken over 2 nights, both with near full moons. I still don't know why I chose this as a pair to image, rather than the traditional Heart and Soul, probably my only regret. Anyhow, heres the info and picture. 3 hours and 30 minutes of Lights @ 60 second exposures dithered manually probably every 5 images. (Helps to have the dob set up or binoculars to keep me entertained haha). Zero Darks 40 Flats 40 Dark Flats 40 Bias LPS Light Pollution Filter Samyang 135mm Modified 600D iOptron Skyguider Pro Processed in StarTools, also did a little extra tweeks in Gimp afterwards. Edit: Not happy with how it looks uploaded haha, looks a bit more blurry. When clicked on it seems to look sharper, more how it looks on my computer.
  2. Hello there everyone, Was out using the Skyguider Pro last night, for the first time I heard a weird, grindy/clicking noise when slewing one way only, the other way sounded fine still. Not sure what the issue could be as tracking was still fine. No noticeable star trailing using my 135mm Lens at 60 seconds, could of easily push it more, but the moon was restricting that. Just wondering what anything thinks this could be? Wanting to take it with me when I go away on October 2nd, so hoping its not something that needs sending off. Have attached a video with the sounds, cheers Grant 20210924_081128.mp4
  3. When using my ZS61 I had this trouble also, before even trying platesolving I just bought a red dot finder. Now when using my ZS61 I dont even think about plate solving, never struggled to find a target with a red dot finder. Usually find it first or second time, then adjust a few times for framing. Edit; Although I don't take anything away from platesolving, most people who are a lot better than me at this hobby use it.. at this moment in time, I've just never had a use for it.
  4. Messaged as didnt want to overtake your post Cheers
  5. Your images always give me hope that Startools is the right thing to use, I just need to be able to use it properly! Got some new dithered data on my heart nebula, not having much luck with it. Its gotten rid of the walking noise, but still very noisy, could only get an hour though before clouds rolled it. Just experimenting now stacking it with old data.
  6. Yes I always thought that above autodev, although it brings out loads, it also seems to make the image look way way overprocessed, but I suppose you can tone things down later on. But I'll take a look at the manual thanks For some reason when I first read APP I thought you meant photoshop (Idk how ), so I thought there might be something similar on GIMP, but then I realised it wasnt PS. Ill give it a go again after gathering more data with Autodev rather than Filmdev then, I forgot about the ROI tool in Autodev. About dithering, its something I really want to do, but how do I go about it without a guiding set up? Cheers!
  7. Thank you! Hopefully them teething issues are sorted for our next clear night Ill try increasing the subs a little next then, see how it goes after stacking. Unfiltered I did do 90 seconds once not even thinking about the histo, only looking for max without startrails. Then when it came to stacking it was still rather bright. And a 'light brown' in the unprocessed tif (Thought they were meant to be pretty black until processed). But now I have the filter I'll try again Brilliant picture also, hopefully I can come close to such a result! Yeah I use the 'filmdev' too (I assume thats the manual one?) Autodev-Crop-Bin-Wipe-Filmdev. What minor tweaks are those you do in APP may I ask? Hopefully I can do something similar in GIMP. Cheers
  8. Hello everyone! First clear skies I've had since a recent purchase, wanted a modded DSLR but didnt want to get my 800D modded as I use it for daytime also, so I brought a second hand modded 600D with a LPS filter courtesy of @teoria_del_big_bang - Thank you very much again and was nice to meet you . So now going to use my 800D for Reflection nebula only, and the 600D for everything else . But last night was the first oppurtunity I had for a test drive, sadly it was intermittent cloud coverage, but just left it running away and deleted anything ruined by clouds! Was also a 84% or so moon, but nowhere near the object, still a far from perfect night though. Now I do plan on getting more and more data on this, but was too eager just to leave it unstacked and editted, as I wanted to see what I had caught. Aiming it towards the Heart and Double cluster (Wanted soul too, but that would leave too much near the edges, at risk of being cropped out after a few nights and bad framing). I was impressed from the first sub, actually being able to see the full heart on a single sub of 40 seconds. Sadly that brings me onto another problem, even with the LPS filter, sky glow was still troubling me with my Samyang 135mm, even stopped down to F4.0, I understand the moon wouldnt be helping, but I've had the issue before without a moon, maxing out at around 40-50 seconds before the histogram goes too far to the right and the image becomes bright. Is this a common issue with this lens in a bortle 5? One more problem I'm hoping I have the answer to myself, but just want it confirming. I process in startools, is this 'mottling' effect, that is basically the space between everything, stars, nebula etc, caused by noise? Made worse by only 1 hours data? So getting more data would improve the SNR and there for reduce the mottling? I can see its walking noise also, but don't have a guiding set up yet so can't dither. Here it is anyhow, critique as usual pleaaase 1 Hours data @ 40 seconds per sub 20 of every caliberation frame Modded 600D LPS Filter SGP unguided And the odd cloud.
  9. It all tordapends how far you're willing to travel, for us in the Midlands, that is the sort of light pollution you kind of have to put up with. Unless you're willing to drive out for 2-3 hours. For example my nearest (That I know of) Bortle 4 is a 30minute drive, but then to get to Bortle 3 probably around 2 hours, bortle 2 about 2:30-3 hours. Even though I live in a smallish town, I find it worse than living in certain big citys, because any direction I drive in, I'm driving towards another damn city. North Derby and Sheffield, East you've got Leicester, West Stafford and Stoke, south Birmingham and Coventry. https://www.lightpollutionmap.info Check that map to see how far you're willing to drive My own personal experience is, I don't drive out for a night to observe or image (probably reflects in my images :DDDD, but people get brilliant images from worse skys, so its just because I'm learning haha). I want to drive to the bortle 4, but when push comes to shove, I just set up in my bortle 5 back garden. But what I do is, whenever we go on holiday, I always eye up the darkest skies and make sure I go on a new moon week. Earlier this year I went to Northumberland, turned out to be a cloudy week and got 1 clear night, but it was breath taking on that clear night in a bortle 2, pointing out constellations becomes hard as they're drowned out by thousands of other stars you could never see with your naked eye from anywhere else, clear views of even the dimmer parts of the milkyway around Cygnus (Didnt stay up late enough for the core to rise). In october we're going down to lizards point in cornwall, also bortle 2-3! But also remember clouds ruin your experience, so don't just go for the dark skies, we go to walk to dog and see national parks, nice beaches and new views, if we get any clear skies its a bonus . Sorry I feel that this kind of went off on a tanget, but I feel I needed to explain my answer and what I do personally
  10. Trouble with the peaks is, its a very populated national park in the park itself, but also surrounded by major citys. Mancs, Sheffield, Derby and Notts. I always find unlike a lot of other national parks, the peaks really doesn't have decent dark skies, bortle 4 at best I believe. So where ever you point the camera, lower to the horizon are big horrible glows.
  11. I'm not too sure how long you've been in this hobby, but to a beginners eyes, this looks like a fantastic photo, as if you've been doing it years. Sorry I couldnt come up with any constructive critism, but I can't, its 10x better than anything I've produced!
  12. Yea a modded camera is something I've wanted.. Don't want to fork out the money for an Astro camera with a decent sized sensor, as I understand you have to spend above a grand for something with a decent sized sensor. But I am getting a modded camera this weekend, been reluctant to mod mine as I use it for daytime aswell. But I am looking forward to being able to experiment more with HA targets, and can still use my 800D for reflection nebula. Not gotten into guiding yet, so I have not been able to dither. As usual tried starting this hobby as cheap as possible, now wanting more and more things, such as a guiding set up haha. But thank you for the advice! Thanks for the effort! Its considerably better than mine But arent the text files created when stacking in DSS anyhow? Thanks for that Didnt even notice the light pollution before cropping! Have you uploaded it? I wanna see
  13. Hello everyone. Decided to try and image the western veil a couple of nights ago, got just under 4 hours of data. And I just cant seem to crack it. I feel all of my current photos to date have often been quite grainy, cropped and uncropped. From the Andromeda which was hardly cropped, to this, which is cropped more than I wanted to something unusual going on in DSS which I can't figure out. First issue, the image DSS keeps producing has a lot of star trails at the top, but non at the bottom, this is being caused some how by the first nights data, as when I only stack the second night, this doesn't happen. But I don't wanna throw the data away, as I am trying to bring out as much nebulosity as possible, just to practice processing. I have scanned all through the first nights. But due to this I have had to crop it more than I wanted. I will upload the original TIFF so you can see for yourselves Second issue is one I can't get away from on any picture, it always looks grainy, overprocessed, and just unrealistic, like a cartoon, not matter how much I seem to crop. How do I get away from this? Anyhow here it is, Tell me what you think. Around 3 hours and 45minutes Lights @ 45 seconds each @ 1600 ISO. 25 Flats 25 Dark Flats 40 Darks 40 Bias EOS800D ZS61 SGP VEIL5.TIF
  14. Hi there! Think I sorted the problem, today I pointed it straight up at the sky, rather than an angle, and no shadow at the bottom. Thanks for the reply though!
  15. Hello there! After taking some flats and stacking them to a set of data, its basically made the bottom of my picture super light, where the flat is super dark. Just wondering how I can amend this. I do the T-shirt and daytime sky method, keeping the t shirt tight with one of my fiances hair bobbles! Thanks in advance! IMG_1252.CR2
  16. Definitely an impressive improvement from the first to the second attempt! I'd be well happy!
  17. Looking nice! What camera was this taken with? Working on the Witches Broom nebula myself last night and tonight, using a unmodded DSLR, so wondering if my results may be similar.
  18. Such a great idea, Will definitely be trying this out on my next opportunity
  19. Thank you Gonna have another play with processing it on the weekend I think
  20. Yes it does! I use layer masks for stars but for some reason never thought of using it for the core, good idea My thoughts exactly, I was hoping for more color, and if you stretch it enough it does come out, but so does more noise
  21. Such simple but such brilliant advice I didnt know about, with a very very slight levels adjustment in GIMP and adjusting the white point, its brought out more detail, whilst still not revealing too much noise! I didnt want to stretch too much as to not overexpose the core. Cheers! Updated below Thank you! I start in startools, then as I'm not too good with the colors in startools, I do some RBG levels adjustment in GIMP, and also run their noise reduction to see if it improves it further
  22. Hello everyone, Been inactive for a while due to terribly cloudy skies. But finally a target is up more suitable to my setup that I can actually capture from my backyard, although many HA targets are up and visible from the backyard, my camera is stock (Will change in september when I purchase a modded camera , a decent astrodedicated is way way way out of my budget at the moment). Although I feel that the target is still reasonbly low in the skies at the moment when I start imaging at 23:00, which I think is reflected in the photo. But it will glide across the zenith later in the year, which I will then target it again , for hopefully more exposure time also. It's taken me a while, but I think I am happy with the finished product. EOS 800D iOptron Skyguider Pro ZS61 Its 2 hours and 30 minutes worth of 45 second exposures. 20 Darks 40 Bias 20 Flats (First time using flats also, didnt know it was easy as a white t shirt, elastic band and pointing it towards the sky!) Let me know what you think Critism always welcome! Grant
  23. Seeing it makes me even more jealous!
  24. Such a nice first image Jealous of some of that set up! I'm the same with credit, never use it.. All my upgrades come from buying and selling, don't even like to fund this hobby with my day job
  25. Hello there! Knowing I would have a clear night on Friday, I was preparing myself to image the whole Veil Nebula in Cygnus with my samyang 135mm. Sadly, after watching TV and getting up at half 4 every morning for work that week, I fell to sleep at about half 9 and woke up at half 11 (When I should of already been imaging!), So I got up, and with a slight rush I went out and set up, trying to find the Veil after setting up. After a few frustrating test shots at different stars trying to find the right one, I came across the Sadr region, and as I didnt want to waste anymore time, I just thought, what the hell, Ill image this instead. The shots looked good, surprising myself at how much HA the unmodded 800d was picking up, and almost clearly seeing IC1318 in a 60 second exposure. After seeing that, and googling other peoples un modded attempts, I was excited thinking it was going to be my best image yet! Sadly this wasn't the case, although I truly believe the data has potential, but my editting skills just don't. I've tried editting in both GIMP and startools multiple times. But I am struggling with the glow of the milky way, washing out half my picture and the crescent nebula area. In my best edit, which I will post, you can clearly see all of the nebula I was trying to pick up, but half of it is washed out. Advise on this will be greatly appreciated, on how to darken the glow of the milkyway without loosing data on the nebulas. I also think flats would massively help, but still trying to find the right equipment to do this with. As always I will post my attempt, which was done in startools, and the TIFF incase anyone else would like to tackle this . As always the details; Canon 800D iOptron Skyguider pro Samyang 135mm 1 Hour and 30 Minutes of lights @ 60 second exposures. 25 Darks 25 Bias sadr3rd.TIF
