  1. Hi Carol, I haven't long bought the camera to be honest. SX are offering a modification to the main board to decrease thr readout noise (typically between 20 to 30%). I will give it a try along with dark frames, and ensuring the camera is consistently cooled If all else fails then I will be looking at alternative options Ryan
  2. Hi Vlav, I managed to have a good go at salvaging what data I had. Being my first CCD/Narrowband image I am really happy with my attempt. Also I am excited to see what data I can capture with consistent cooling and more calibration frames. Its far from perfect but a good start for myself I feel. Thanks again for all your help pal. Stargazerslounge is a total god send for people like myself All the best Ryan
  3. Hi Xiga, I hope you don't mind me asking, I have followed your instructions to process a starless image of my stretched 16bit tif mono and rgb images. However after I edit either in their respective notepads, the programme fails to process with the following message. Do you have any idea what I am doing wrong? Thanks Ryan
  4. That's amazing Vlaiv condsodering how little data I have. Did you use just sub 8, 9 & 10 of the Ha. I will attempt using your workflow Much appreciated pal. Ryan
  5. That would be such a help I shall look forward to it. Thanks for all your input Vlaiv
  6. 16bitTIF Ha HDR Tonning.tifThat looks much much better Im not sure I could replicate that haha. I've been experimenting with stacks. So far keeping all my DSS settings to average, applying a median noise reduction filter and applying just a 1 pixel hot pixel removal so far seems the best. Anyhow, when converting from a 32bit tif to 16bit in PS and converting to HDR toning, it produces this which looks far better than anything I have done so far with my Ha data, a little bright and soft in areas but I will try adjusting such areas. What do you guys think? Thanks Ryan 16bitTIF Ha HDR Tonning.tif
  7. These TIF stacks include the median noise reduction and hot pixel removal, however they were stacked prior to changing my stacking settings so they are all stacked via kappa sigma clipping. If this isn't of any use I can restack using average settings and upload 1st thing tomorrow Thanks again Ryan Autosave028 Stacked Ha with 3pix noise reduction.tif Autosave016 Stacked SII 3pix noise reduction.tif Autosave016 Stacked OIII 3pix noise reduction.tif
  8. Amazing thanks P.S I forgot to change the hot pixel removal from 3 to 1. Ryan
  9. I am unable to combine FIT files in PS, so I hope you don't mind that I have attached all three new stacks including 3x3 median noise reduction and a 3 pixel cosmetic hot pixel removal. Apologies I forgot to change to 1 pixel hot pixel removal.

  10. Ok Vlaiv, I will take a set of darks tomorrow night. All subs were 10mins long, how many do you recommend I take? What's your drop box address, I will post all my subs 1st thing tomorrow.
  11. Hi Carol, Thank you ever so much for your input. The H18 is known to be a noisy camera, however I've been advised to apply a 3x3 median noise reduction during stacking (which this stack does not have). Can I restack including noise reduction to see what you think? Thanks again Ryan
  12. Thanks for your efforts Vlaiv. Yes that's correct, due to no set point cooling and SX's H18 manual recommending a 3x3 median noise reduction over dark frames,. I didnt take any. Next time I'm out I will take the necessary darks in between each filter change. Can I upload a new stack of my Ha data including the median noise reduction to see if it helps. Also I will apply a cosmetic removal of hot pixels in DSS. What size pixels should I use to remove them? Thanks Ryan
  13. Hi Vlaiv, Here are my three individual raw stacks straight out of DSS. Hi Vlaiv, Here are my three individual stacks in 32bit Fit straight out of DSS. The amp glow in the Oiii opposite due to a auto meridian flip. These stacks are integrated exactly as you mentioned above, however I unticked background calibration and debloom tabs as I wasn't sure whether to include or not. Thanks for taking a look.

  14. Hi Knobby, Thank you also for your reply. Im quickly discovering its a dark art and I need a magic bullet. Vlaiv has kindly offered his help which I can't thank him enough for. Thanks again Ryan
  15. I'm using a Starlight Xpress H18 mono with the added external cooling fan. Yes apologies I failed to mention that I didn't include my Ha reference frame in stacks of sii and oiii OK Vlaiv, when I get back home I will restack following your instructions and post as 32bit fits Thanks again pal Speak soon Ryan
  16. Hi Vlaiv, Thanks for your reply. During integration I didn't drizzle, will try and give a break down of my stack. Used the best Ha frame as a reference for all 3 stacks. Used a 3x3 median noise reduction as the H18 is really noisy. Lights, bias and flats are stacked via kappa sigma clipping and applied to the three stacks. In the cosmetic section I did apply a 3 pixel removal of both hot and cold pixels (will this effect the weired grainines)? Maybe I have gone wrong during the stacking process. Thanks again Vlaiv
  17. Hi guys, Can anybody help a prevent a Welsh guy from throwing his laptop into one of Brecon Beacon reservoirs I have gathered my 1st set of narrowband images of the Heart Nebula (10x600sec through each Ha, Sii & Oiii). I would really appreciate some help with a basic workflow of my rgb image prior to applying my Ha stack as a luminance layer. All stacks are calibrated with bias, flats and a 3x3 median noise reduction as I'm using a SXVR-H18 mono camera. I've stacked using DSS & am using Photoshop 2019 to post process. I have Adam Blocks Every Pixel Counts video tutorials & Steve Richards Dark Art book, noel carbons action toolset, HSLVG & GradientXterminator plug-ins at my disposal. However I am struggling to determine what steps to take and when. I've decided to assign my stacked filter sets to the SHO Hubble palette. My rgb and Ha luminance layer are aligned and cropped accordingly Here are both my merged rgb Sii-red, Ha-green & Oiii-blue and my Ha luminance image originals. Any help would be very much appreciated. Thanks guys Ryan 16bit tiff Ha aligned to rgb.tif 16bit tiff RGB aligned to Ha lum.tif
  18. Thanks for your info guys. The csx-304 may be the camera for me in readiness for winter. I am keeping a close eye on all your comments Clear skies
  19. A quick update, I had to carefully drill them them out enough to allow me to slide the stock focuser out. Now it's time to order some quality M4 screws. Would anybody happen to know the length? Thanks Ryan
  20. Hi guys, Thank you all for your input, it's greatly appreciated. I am going down the extraction route. I heated one screw before using an elastic band to help grip. The 1st screw came half way out, however the head fell snapped. The next two screws though aren't budging. I understand its far from a quality scope but surely Synta would insert a slightly better grade screw (in my opinion). Thanks again Ryan
  21. Hi guys, I have a Baader Diamond Steeltrack focuser to replace my stock one. However the three screws holding the stock focuser in place don't want to play ball. If I try any harder I am easily going to strip the heads. Does anybody have any tips or experienced similar problems? I cannot afford to be spraying WD40 for drilling screws out. Thanks all. Ryan
  22. It's a wonderful image well done. I have recently purchased the modded version. I've had a few test sessions with it and think I am ready to push it past 5 minute subs. I'm hoping to acquire a 460ex mono soon, yours seem to be providing amazing results. Does it require refocussing between each filter change? Thanks Ryan
  23. Amazing inage Caole?? May I ask, are there any secrets to mainatining guiding accuracy with the HEQ5? Thanks Ryan
  24. Hi Vlaiv, Thanks for your reply pal. Ok so all in all what is my best option? I am keen to image galaxies so would prefer not to change for a shorter FL imaging scope. Maybe a guide scope with a longer focal length, or what about a OAG. I'm not familiar with OAG and what the advantages a nd disadvantages are. My current payload is 7kg so adding a larger guide scope will put me close to the limit. Hmmm decisions decisions, what do you guys advise? Thanks again all. Ryan
