We had a patch of clear skies last Sunday night, and even though it was bitterly cold (and there was ice and snow everywhere) I made the executive decision to get outside and have a go nonetheless. I have to setup and teardown each session, but thankfully I was able to move the car a few metres and take advantage of the nice dry (and ice free) ground underneath. The plan was to grab some OIII data to go with the Ha I captured on the Heart Nebula a couple of weeks back (see link below) but all I could manage was 8 x 1200s before the clouds rolled in for good. In fact, 3 of the 8 subs were- 16 replies

Hello all, I am trying to process data captured on friday during almost full moon, and I'm having a hell of a time of it.. Due to the full moon doing it's best sun impression my target was an open cluster (NGC 225 in Cassiopea), thinking it would be doable. I was using my 2" Explore Scientific CLS filter, my unmodded Nikon D7100 and captured 92 usable 45 second subs at ISO 400. Calibrated with bias and flat frames and stacked with linear fit clipping as the pixel rejection algorith. The mission for the night was not getting particularly good data, but getting decent tr -
The Great Barred Spiral Galaxy ( NGC 1365 ) in the constellation Fornax edit: new version with new long exposure data ( 52 x 240sec ) and better dark subtraction / dithering to remove streaks in the noise and amp glow. This also allowed for a greater stretch revealing more faint data in the galaxy and small faint fuzzies in the image ..

Hey guys Here's a quick WIP version of the Heart Nebula taken with my usual gear, the Nikon D5300a, SW 80ED, and HEQ5 Pro. So for this constitutes: 11 x 1200s and 3 x 900s of Ha (so 4 hrs 25 mins in total) 30 Flats 50 Bias As usual, stacked in APP and processed in PS. It's well placed here in the UK right now so I'm hoping to get some OIII in the coming weeks. I'm never quite sure how much to process these images. Aside from the usual stretching, apart from a mild amount of deconvolution, sharpening, and contrast enhancement that's all I tend to do really.

Hi All I'm new to Astronomy/Astro Photography and a long time user of Canon DSLR's - particularly the 600d so I know it very well. I recently bought another 600d from ebay and its got an amber tint to all White Balance presets - no problem for me in general use as I use a custom WB anyway and can easily get rid of the amber tint thusly. Of course I contacted the seller who offered a price reduction for the 'fault' which was satisfactory to us both. Issue resolved, everyone happy, end of story. Now on the the 'good' bit - possibly... During our negotiations he told me he had

Hi all, This one is a composite from two of my telescopes : TS APO with reducer = FL 550mm F5.1 iso 800 : 13x20 min Ha + 6x20 min OIII TS Imaging Star 71 = FL 350mm F5 iso 200 : 82x3 min RGB (only Hutech IDAS LPS-D1 used) I am new to NB processing, so I followed this tutorial but also improvised some. Weather did not permit more OIII data, so I squeezed as much as I could out of it. To start with, I only used the green channel from those subs because that channel had the strongest signal. Filters are Astronomik 2" 12nm. Today I would have used iso 200 even for

Hey guys We had a couple of clear night over the weekend (finally!) so i decided to put the man-flu to one side and get back to imaging. I mostly went for the Rosette Nebula (still a WIP for now) but once it passed behind the neighbour's house i was starved of any other Ha targets. The big, bright moon was well up at this stage, but the skies were crystal clear so it seemed like such a waste not to use them. So, i decided to go for M81 & M82, seeing as they were well positioned, and just hoped that shooting galaxies under a bright moon wouldn't be anywhere near as bad as shooting nebu

(The heading was a click bait, admitted. Who would click on just another "Elephants Trunk" ;-) In lack of fresh data due to perma clouds over my head, I recycled some old data trying to compete with myself and maybe progress some in post processing. I choosed a target that I have found to be very difficult to process, and I think it came out a little better. What do you think ? All suggestions are welcome. The brightest orange star to the right in my image is a red supergiant called The Garnet Star, or Mu Cephei. It´s a "runaway star", travelling with a speed of 80 km/s relative to t

WARNING!!! The following post contains an entirely under-whelming image! With nothing but clouds here for what has seemed like forever, and no sign of any new data in sight, i decided to turn my attention to some test data i shot back in August of last year. The reason for choosing this, is that i wanted to see how far my processing skills had come along, and i knew this one would be a serious challenge, as i had basically everything working against me. I shot this near the end of August while testing out the new imaging laptop and rowan belt mod for the HEQ5 Pro (which i had instal

Hello fellow gazers... I started shooting this one back on Feb 20, when i grabbed 11 x 1200s of Ha subs. 4 of the 11 were not of great quality, due to some light intermittent clouds, but i included them anyway in the stack (such is the trust i place in APP's 'Quality' algorithm). Then on March 3 i finally got another clear night, so while i waited for the sports facilities floodlights to switch off, i grabbed a short set of 20 x 90s RGB subs (just the D5300 with no filter) so i could use them for RGB stars. Then afterwards managed to grab 12 x 1200s of OIII subs. It's been a b

Hi all, Here is my first go at the witches head nebula and I am searching for your expert advice and knowledge. This is a total of 80minutes of 3 minute exposures on my dslr and stacked in dss. I have stretched the bejeez out of this in gimp and I am quite frankly disappointed with the detail. I would have thought with an hour and a quarter of data that I would be able to tease something more impressive of the nebula? What do you think?

Evening all, Im a massive beginner to this and have been offered the above mount (think the person thinks I use telescopes) but I’m heavily into astrophotography, my question is; can you get a dslr mount for this or is it purely for telescopes only? As a beginner it would be a great bit of kit that doesn’t break the bank, helping me progress. Any help kindly received craig -
Hi guys Been busy the last wee while, so haven't done much imaging lately, but i did at least finally get around to processing my Soul Nebula data from a couple of weeks back. So this is 220 mins of Ha, and the same again of OIII, all 20 min subs. With the usual 30 flats and 50 Bias, with aggressive dithering. Shot through a SW 80ED on a HEQ5 Pro mount. Captured in SGP, pre-processed in APP, and post-processed in Photoshop. I used a slightly different method this time. Normally, i stretch the OIII data to the absolute limit, and then combine the stacks in Photoshop, but

This one is a composite from two of my telescopes : Meade LX200-ACF, FL 1600mm, F7.8 (with reducer) 55x10 min = 9h10m @ iso 800 TS Imaging Star 71, FL 350mm, F5 186x200 sek + 4x300 sek = 10h40m @ iso 400 The two images are aligned with Registar and blended together in PS. The small APO is attached to the CW bar so I can image with both scopes simultaneously. I previously posted the LX200 closeup image here : Ragnar

Hi guys With the weather here in the UK being so bad recently, and with work commitments and other boring life stuff going on I haven't done much imaging lately, but I did finally manage to get out and grab some OIII data a couple of weeks ago to go with my old Ha data of NGC 1499 from back in September. The Ha data was from first light for the newly modded D5300 and Baader Ha filter. We have an outdoor sports facility only a couple of hundred yards from our house, and annoyingly the ridiculously bright floodlights don't turn off until after 10pm on weekdays, so even though there wa

Hi guys I've been staring at these for long enough now that i'm effectively going blind to them, so i think it's time to post them and see what you guys think as well. It's late, so i'll keep this brief! 10 x 1200s Ha (2" Baader) 9 x 1200s OIII (2" Baader) So not much exposure at all really, but it's all i'm going to get for a while. The Ha was shot low on the horizon, and with a big bright moon up, but at least i managed to get the OIII the following night (mostly) before the moon made it's re-appearance. The usual Bias, Flats, and aggressive dithering.

Just thought I would share my first DSO images I took of the Orion Nebula. Not great but better than I expected them to turn out given I had never taken this kind of picture before, and it was completely in the moment without any prep. I took these on my Canon 60D with a Canon 18-200mm lens. F3.5 apeture, 1.5 second exposure. The first image was at 1600 ISO, the second at 3200. The first image has a bit more fine detail, at the cost of losing how big the nebula is and some of the color. The second has a lot more color and shows more of the nebula, but a lot of the detail is lost in

This is a mosaic from one camera and two telescopes on three occations. Background is done with a 700mm F6.5 apo but for the galaxies I used my Meade LX200-ACF plus 0.78x reducer. Each one of those got 26x15 min @iso200 with a modded Nikon D7000 and CLS filter. Mount is HEQ5 Pro, guided with a standalone NexGuider. Captured with DslrDashboard on Android tablet. No darks, flats or bias used. Processing with Registar, PS and Topaz Suite. Ragnar

Hi all, It's been a while since I've posted a new topic unfortunately the weather has been horrible for the last month. I have saved up enough now for a new camera I had bought a cheap bridge type camera but wasn't that great and I'm looking to buy a DLSR and then hopefully a SA if I enjoy it. My max budget I think is no more than £200 I was hoping you could give me some recommendations for one that's slight beginner friendly but still good enough and also the best type of lenses to use? Many Thanks -
So, I have gone and got myself a Skywatcher Star Discovery 150p, which has so far proved to be a very good little scope and I've had some very good results. I have now got the bug for imaging and have gone out and got myself a second hand Nikon D5100 and verious other equipment needed to do this, only to now find I can't get Prime Focus!!!!!!!! So the only way I can image is using a barlow x2 which obviously changes the F ratio from F5.5 to F11 slowing everything x2 this isn't to bad for planetary imaging but for DSO images not so good!!! After searching through lots of videos on to -
So I am not quite total beginner to astro images, but I am not hurrying to get to telescope range due to various factors and I did not find similar topic on several first pages of search, so this topic might be best suitable here. I have a camera that has a possibility to track astro-images up to 5 minutes, which is enough for me to take the Milky Way shots and even some Nebulae, clusters and similar level images. I have moved to the location that is a more light polluted than the one I lived before (from http://darksitefinder.com/maps/world.html : I lived close to the edge of yellow and -
Hi there! I´ve had a break from astrophotography. I lost all lust for it during last winter after my father suddenly passed away. Really getting the lust for AP back now and while waiting for the dark nights to return I reprocessed my M42. This is one of the photos I will use for an upcoming exhibition I´m participating in. I really think this was in improvement compared to my latest version. Tighter, less fuzzy stars, better colours. 28*120 + 39*180 + 27*300 seconds of RGB 23*600 + 1*900 seconds of HA (12 nm filter) 5*10 + 12*6 seconds for the brightest area All in all 9+ hour
