Hi all,

Novice here, 2nd attempt at imaging DSO. Aimed to capture M51 last night but think I might have been off target. I thought my polar and synscan alignment was pretty good and synscan seemed to be on target for other objects.

Can anyone tell me if I was off target or just didn't get enough data? I have tried matching the surrounding stars to other images of the area but can't seem to figure it out. I have attached the .tif output from DSS. I have played with levels and curves but can't reveal anything yet.

If it's bad news, can anyone at least identify the faint fuzzy for me?

Thanks in advance

 

Details:

Skywatcher 200PDS + HEQ5Pro mount

Lights 60x60sec ISO 800

10 darks, 10 bias

Here you go!  Just a little bit off.  The faint fuzzy is NGC 5422.

I got this result from http://nova.astrometry.net which took less than 20 secs to process it.

There's a free program, All Sky Plate Solver, which can achieve the same result if you don't have internet access from your imaging rig.  Takes a little bit of setting up but once done it solves very quickly and removes a lot of the frustration (been there, many, many times!)

Ahh thank you, much appreciated.Looks like they tools could come in handy.

So I was on the wrong side of Ursa Major, jeees! Learning curve indeed. At least I captured something :D

If you navigate to a nearby star you recognise eg Alkaid, and Synch on it, then the small goto move to M51 should be in your frame, if not spot on.

Centre Alkaid

Press Esc for several secs until screen flashes

Enter will Synch

Then goto M51

You could also use the Synch star to focus

Thought I'd provide a follow up on this one. Thanks to your advice above, I managed to track down M51 last night. My star alignment was poor first time around (thought I had aligned to Arcturus but it was a nearby star...don't ask haha) but with all sky plate solver I was able to figure this out early and redo my alignment!

Only managed around 30x60sec subs before the clouds rolled in but was just so glad to see the whirlpool pop up on BackyardEOS! Had a quick play at processing today. Need to study more processing tutorials but chuffed with what I managed to pull out from such little data

Thanks again!

Well done!

All sky plate solver isn't for everyone, but when it works it's brilliant.  

You might want to check out the free version of Astro Photography Tool.  Its Pointcraft function can put you on target (it uses APT) in just a few minutes, starting from almost anywhere.

      After some trial and error I'm getting some very good guiding results with PHD2 now. 60mm guidescope and ASI290MM mini camera. The M42 image taken late March was 12 x 15 second exposures taken manually with my dslr / C8 and a stopwatch. Stacked in DSS and played with a bit in GIMP. On the night I couldn't get APT to register the camera - turned out to be the mini USB cable (although later trials point to the socket in the camera being a bit loose too). 
      Bought an iOPTRON iPOLAR that arrived on Friday and had a play with that which has resulted in near perfect polar alignment. 2 star alignment and an additional 2 calibration stars on my Advanced GT mount means I'm getting very accurate GOTOs now and PHD2 (through the ST4 port on the ASI camera) seems to be guiding very well.  Last night after more cable faffing I managed to get everything working together to the point where I felt confident enough to leave it running by itself for an hour and a half (45 minutes of 180 second exposures plus 3 minutes each exposure to save the file - I've since found out I shouldn't have noise reduction switched on in the camera - DOH!) so M51 is 15 x 180 second @ ISO 800 lights and 5 x 180 second darks.  A little manipulation in GIMP and I think it's come out very well. Obviously still have a lot to learn and I'm going to have to start taking much longer exposures  but I'm quite pleased with these 2 pictures. 
      Graeme.

      2020 hasn’t been a great year for anyone, but we’ve had a good comet, and some clear nights. I haven’t been the most productive, or even a very good imager this year, but I’m quite pleased with what I’ve learnt, narrowband has been a revelation . So I thought I would share a few of my images, and a video I put together or them. Thanks for all the great images and tips that have been posted. Wishing you all a happy Christmas and a great 2021.

      Hi, I have taken mono LRGB images of M51 with my new ASI1600mm-PRO.
      I have a mix of 30s, 60s, 120s subs. 100 darks, and 100 flats for each filter. About 4 hours total.
      I Used DSS for alignment and stacking, then Pixinsight for LRGB combination.
      My issue is that i'm not happy with the colours, the stars all appear white and the background is strange.
      I have attached the Aligned LRGB images.
      Can anyone point me in the right direction? Thanks!

      This is from a couple of nights ago.
      It clouded in quickly, so I didn't get much data. The temp was 2C, and I'm self-isolating - so that was also a factor! I only took 5 darks before I gave up and went to bed. I'll take more when the temp is right.
      This is 140 min integration time on a new Canon EOS Ra with 17x500s exposures, and no filter (from the city).
      Processed in PI and Photoshop - I should have used more star masks but the data aren't good enough to warrant the effort I think. I also had difficulty with flats - I tried a range of exposures with a Gerd Neumann panel, but I think they were all too short. Will go longer than 0.3s next time - very hard to figure out flat exposure on DSLRs, and APT's tool doesn't work for DSLRs yet.
      I think I'm obsessed with M51 - and I know I'll be back to it again.
      Stay safe everyone,
      Barry

      First attempt at any DSO other than the brighter stuff like M42 or Andromeda.
      Learning to use the AZ-Gti /Sharpcap polar align / windows synscan app / APT platesolving ... And guiding ! all in one night ?
      all went well so had a quick 30 mins on M51 (first time I'd ever managed to actually frame it ... Plate solving is amazing)
      90 second subs gain 420 and 5 darks and synthetic flat for dust bunnies / gradients
      Wish I'd have gone longer now as tried a 5 minute sub once guiding was working which looked good .
      Very noisy but only 30 mins .
