  1. Managed to get a second session in on this target last night. Shot in LRGB with a ASI183MM P using ZWO filters. SharpStar 61 on a CGEM . There were 8x240sec images with each filter for a total of 128 minutes of Time-on-Target (ToT). All processing done in PixInSight.
  2. Yes over-sharpened or sometimes called "a look inside".
  3. Guess that doesn't work here.....
  4. Shoot the Helix Nebula over 4 nights, ended up with 31 images @ 240 seconds per image. ASI533MC Pro in a SharpStar 61 EDPH II with a l-eHance filter. Stacked in Astro Pixel Processor ,Processed in PixInSIght, and some had some time in Luminar AI. Several versions: [url=https://flic.kr/p/2nGBTKZ][img]https://live.staticflickr.com/65535/52311847547_061e7b555b_k.jpg[/img][/url][url=https://flic.kr/p/2nGBTKZ]NGC7293 Aug25[/url] by [url=https://www.flickr.com/photos/140934176@N02/]Brent Secord[/url], on Flickr [url=https://flic.kr/p/2nGNiwB][img]https://live.staticflickr.com/65535/52313878627_96060d294a_k.jpg[/img][/url][url=https://flic.kr/p/2nGNiwB]NGC7293 2 Night B[/url] by [url=https://www.flickr.com/photos/140934176@N02/]Brent Secord[/url], on Flickr [url=https://flic.kr/p/2nHm7xr][img]https://live.staticflickr.com/65535/52320085255_2ccd127eca_k.jpg[/img][/url][url=https://flic.kr/p/2nHm7xr]NGC7293 4Nights[/url] by [url=https://www.flickr.com/photos/140934176@N02/]Brent Secord[/url], on Flickr [url=https://flic.kr/p/2nHspkR][img]https://live.staticflickr.com/65535/52321312443_3ef5b9cdd6_h.jpg[/img][/url][url=https://flic.kr/p/2nHspkR]NGC7293 Crop[/url] by [url=https://www.flickr.com/photos/140934176@N02/]Brent Secord[/url], on Flickr
  5. August 22, 2022 Scutum Star Cloud. ZWO ASI533MC Pro, L-eHance Filter, SharpStar 61 EDPH II scope. 2x2 mosaic with each panel consisting of 6-240sec images. Capture/Control StellarMate Scheduler. Integrated with Astro Pixel Processor, tuned in PixInSight and a quick round in Luminar AI for a couple stubborn jet trails.
  6. You guys are Officially FUNNY! 33C here today with a 4o km/hr breeze, going down to 10C tonight. To live where I do (Bortle 1-2 and can watch my dog run away for 3 days) you have to be "Tough" or "Stupid"! Jury is still out on me!!!!
  7. Nice image, and I agree with you, the stars are distracting from the focus object. I see a steep learning curve for you my friend, I see the purchase of a PixInSIght license for you in the near future! There are a lot of processing programs out there, and I have tried a lot of them. PixInSight seems to be the go-to for the really good images. Pix has a tool called "Morphological Transformation" which in simple speak is the ability to reduce the tiny stars with one slider and the click of the mouse. It was pointed out to me a few years ago that background stars should/could be a source of Light Pollution. I was embarrassed as all get out that this concept hadn't been seen by me....... It also seems you were almost on the verge of over exposing your image, "less is more sometimes in AP". All-in-all this is a win for your first attempt at NB imaging. Keep at it.
  8. This is a 2x4 panel mosaic captured with a ASI183MM P, Optolong Ha filter. The scope was a 8" SkyWatcher Quattro (Imaging Newtonian) with the SW coma corrector. It was guided by a 60mm Starfiled refractor with a ASI120MM Mini camera. Al sitting on top of a DIY hypertuned CGEM. The Capture /Control program was StellarMate. I used the Mosaic Sequence Scheduler to run my sequences. Once started I sat back and never touched a thing until the sequence was finished. I could have set it up to Park the mount and warm the camera, but as my SkyShed Pod Obs isn't self closing I like to do the shut-down procedure myself. There data for this image was captured over 2 nights running the same sequence. Each panel consists of 6-240 second images with a Gain of 70 and a offset of 8. I always cool my camera sensor to -15C. Processing was all done in PixInSight. For this image I decided to try using "Masked Stretch" rather than "Screen Transfer Function" as STF left me with visible lines of the overlaps to deal with. I will have to wait for the new Moon to capture the Oiii dat and possibly SII data if I chose to go with a SHO image. I am still refining my work flow for Mosaic Capture and Processing. LOL OSC Mosaics are much easier!
  9. That first image was washed out fairly badly. Lets try this......
  10. As with any use of a new tool that Pix has, getting the Mosaic Script to work was a pain. The research was finally rewarded. Took watching several videos, a few questions on the PixInSIght Forum and a few trial runs but be darned if I finally got something I wasn't ashamed of. The image below was taken August 5 of 2021. 3 300 second images of each panel with a ASI183MM P, Optolong Ha filter all stuffed in a EDPHII 60MM SHarpStar triplet apo scope. All wok done in PixInSIght. This rig is my wide FOV and the East Veil Nebula is some spread out... One thing I would recommend when learning how to manipulate the software a Ha filter will show issues boldly (ask me how I figured that out!). The main issues will show up in the overlap. If anyone is interested I can provide a link to the videos that helped me get to this point. When I have longer nights I will gather up some new data suitible for mosaics. When I become more efficient in using the scripts required I could do a video. Comments or questions always welcome. Hint: The image has been cropped, and not where you'd think!
  11. I had a chance to test out v1.7.1 Last night. Not being a fan of using the "latest and greatest". It was suggested that this new version has the Mosaic issues fixed. I have used the following versions of the operating system. v1.5.4 -used to long ago to remember v1.5.8 -stable but lacks the refinement of tools new versions do v1.5.9 -no recolection of the performance v1.6.0 -stable v1.6.2 -Stable v1.7.0 -Problematic v1.7.1 -appears stable after one nights use I did discover the newest 2 versions (maybe more0 offer both the 32 and 64 bit options. On my set-up the 32 bit is troublesome, the 64 bit versions perform as expected. As with any open source program, growing with the development long term will pay off. I have also used APT, Sequence Generator Pro, SharpCap, and Astro Photography Tool as C/C systems. StellarMate and SGP are close to kissin' cousins in regards to tools.
  12. For me the StellarMate with the RPI is the answer. I shoot year round in Canada. Temps can range from +40C to colder tan -40C. My RPi stays out in the Obs 24/7/365 I would never take a computer put there in the cold. The Rpi handles it like a champ. And since I installed a ethernet cable to the Obs from the house, I can run rvrything but the dome open and close and it's rotation from the comfort of the couch! Point being the RPi runs on INDI, NINA uses ANSI. 3 options for a C?C system for the RPi or the PITA upkeep of ASNI drivers..... I use StellarMate, I have used NINA, SGP and APT. While SM has it's faults, they aren't any worse than anything else.
  13. I use A StellarMate with my ZWO OSC 533MC Pro and my mono 183MM Pro. I have both a EFW and a EAF. Seems with the EAF you have to deem what your backlash is for your setup. Once you have that all figured out and saved the EAF is still a crapshoot. Mine will chug away and get close to a optimum focus most times, other times it gets close then takes off with a huge set adjustment. When I last looked into the issue (probably 8-9 months ago) the common conclusion is there was a glitch in the drivers which caused this. I just read that switching it over to linear works best for some. Now I have to go out and fire the system up, come back in (I run remotely only, I am old it is winter and I hate the cold) and re-visit how it all works. At this time of year I am fortunate enough that the temperature stays within a couple degrees of the focus time. On nights where it over-corrects the focus I re-run the auto focus again note the curve and manually set the set to the lowest point in the curve. Sadly I suffer from poor internet search protocol. LOL Finding useful info on troubleshooting is more of a fluke than a talent. And answers from Jasem never quite satisfy issue that I encounter. Being pre-'puter in school and very isolated in a rural area doesn't help in the learnin' curve of 'puter skills. This leaves my with the trial-and-error method...... I should have chosen knitting for a retirement hobby. Not to say that I can occasionally put together a descent image. I believe I understand your desire to get the best raw data you can. Good to great data is far easier to work with in post processing that a sows ear going into to post....
  14. I'm late to the party, but want to thank steppenwolf for posting this gem of his. Being a new PI user does make the art of processing a pretty vertical learning curve! LOL At least when I go back and use other tools like StarTools or PS they seem kind of easy to use!
