What on earth is causing this...π
Ryan_86 replied to Ryan_86's topic in Discussions - Scopes / Whole setups
Thanks for your replies guys. Star tests showed perfect round stars when out of focus. This led me to look at the camera/oag/filter wheel end and it looks I'm on the right path as the oddly shaped stars rotate when I rotate the camera 90 degrees. -
Hi guys, Following the collimation of my laser collimator this is the shap of the red dot exiting my quadruplet refractor. Notice towards the bottom it becomes pointed. I plan to fix a little focus tilt, if this doesn't resolve the problem i guess I'm stuck as it has no collimation screws for the lens Has anybody seen anything similar? Many Thanks Ryan

Hi guys, I'm wondering if anybody has experience adjusting a rack & pinion focuser to fix tilt issues. My stars are triangular and have eliminated sensor tilt and pinched optics. My scope is a Primalucelab Airy 65F with a hybrid 2 dual speed focuser. The tilt is visible especially when I slight tighten the foxuser tube focus locking thumb screw. I removed the focuser mechanism revealing two beefy looking grub screws. I back them out and gave a turn each alternating between the two until a gentle contact was made. This has cured the tilt but am unable to adjust the focuser tube as the grub screws are holding the focuser tube in place. If i loosen slightly to be able to adjust focus the tilt come back. I've contacted Primalucelab but are unable to supply a manual. I'm hoping I've missed how to do it properly. Many Thanks Ryan

Hi Micheal, No there were no warnings following calibration bwfore running a GA. Next time I'll calibrate as close to 0 dec as possible, I can get within 20deg for sure. I didn't manually clear the backlash prior to running PHD2, I'll try that also. Maybe I'm going a bit OTT with this but was a bit taken back by the backlash as I've adjusted the meshing and cant feel any play or binding. Much appreciated ππΌ

Thanks foe your replies guys. Yes Clarkey, I've adjusted the dec and ra worm gear meshing because i could feel some play in both axes. After lot's of adjustments I'm pretty certain there's no backlash or binding. Also the belts move precisely when moved at 0.2x via the hand controller. Also I've adjusted plastic casing where the counter weight shaft goes through and the ra nut behind the polaracope. Balancing is spot on and really smooth. My guiding was consistently at 0.6rms that night even with really strong winds. I'm wondering whether the winds effected it along with my balance on the 3rd axis not being good enough as it does pull to the left when parked and clutches are released. I was unable to take any subs due to my shutter being stuck closed. I'll try these and go again. Does this calibration graph look ok, Indone thia bwfore running thw guide assistant. Sorry guys I've been out of the game for 3 years so am a bit rusty π¬πππΌ Thanks again guys Ryan

Hi oal, just read you post. May I ask, didi you resolve it? My Eq6r pro just reported 3.7 sexonds of dec backlash. I tinkered with my deca and ra worm adjustment because I could wobble axis. However there's lots there, so not sure whether to adjust mechanically again or isnit a guiding setting π€ Here's a pic of graoh, 10 ga. Total rms 0.6 with strong winds π³ No images though, as half of my shutter wouldn't open lol. Thanks Ryan

I love the look/spec of the SS 15028, I can see this being added to my artillery next year ππΌ

sgp v3(sequence generator pro) any better
Ryan_86 replied to iwols's topic in Discussions - Software
Thanks for the info guys, I panicked when I first read about a SGPro annual payment. Anyhow I'll stick to my v3 for now and must admit SGPro is absolutely fantastic. Clear skies Ryan -
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 π¬ If all else fails then I will be looking at alternative options ππΌ Ryan

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

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 -
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

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

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.

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

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.

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 oiiiππΌ OK Vlaiv, when I get back home I will restack following your instructions and post as 32bit fitsππΌ Thanks again pal Speak soon Ryan
