  1. Really? Is that where the majority of the internal reflection problems lie then? Very useful info!
  2. Just as a side note, did you find a dew shield to fit the 130 PDS? I was after something to reduce internal reflections from a street light without flocking and asked FLO about the Astrozap ones who replied that none were suitable.
  3. Ah great advice thanks. I didn't even notice or maybe didn't look far enough down the list to see the newts in brackets. Thanks again!
  4. Here's my quick and dirty PA routine using SharpCap. When placing tripod, try to aim the North leg at Polaris. Run SharpCap and connect camera, set exposure to 2s then run polar alignment routine. Let the first stage plate solve, hit next, release clutch and rotate RA 90° as instructed. My Az is usually over a degree off so I tend to nudge one of the rear legs a few inches, otherwise I'll run out of Az adjustment. I do this till the Az is within 20 or 30 arc minutes. I then adjust whichever has greater error between Alt and Az to within 30 arc seconds, then the other.
  5. Try inputting the ra and dec into APT. Coordinates can be found here: https://theskylive.com/c2019y4-info
  6. Just seen some of the solar images here and as it's something I'd like to try myself with my 130PDS, could anyone advise as to the best ready made filter? I'm looking at the Astrozap Baader one here https://www.firstlightoptics.com/solar-filters/astrozap-baader-solar-filter.html Would the 136-146mm be the most suitable? Cheers all
  7. Hey. It's a Skywatcher Evoguide 50ED, 242mm Edit: misread the question. 2 second exposures.
  8. Hey, For the last couple of nights while polar aligning with SharpCap, Polaris is dancing about when I get close to alignment. I'm then seeing quite bad guiding in PHD until I try polar alignment again. On the second try, Polaris is still dancing about as shown but I guess with a bit of luck I'm getting closer to the money and my guiding looks better with under 1.00" total error. I've played with the settings in SharpCap as far as the black threshold and minimum star pixel but it doesn't seem to change the dancing Polaris, only making it a bit harder to solve.

  9. Comet C/2019 Y4 ATLAS 120x60s @ISO800 / 10 dark, 30 flat, 50 bias Individual frames calibrated in DSS. Processed and animated in Photoshop
  10. Thanks for the excellent advice on this one. I was able to extract the calibrated frames from DSS with the above setting (plus the debayering option). I then loaded one into Photoshop and recorded a new action of stretching it and dealing with noise. Then using File > Automate > batch, point Photoshop at the right folder and away it went. Took about 30 seconds per frame so about an hour of automation. I then created the following gif.
  11. Just found this setting in DSS which should help
  12. @Craney that's incredibly helpful, thanks. I'm gonna give this a crack tomorrow. Regarding DSS creating a calibrated frame prior to stacking, would this be in the registering phase? I'll have to have a check to see if I can pull calibrated frames out of it before stacking. Thanks again
  13. Cheers Dave. I'll have a fiddle and might try Maxim.
  14. Cheers Dave, Sounds like a lengthy process? Would I have to use DSS to apply my calibrations to each sub individually? Is there a way for DSS to do this automatically rather than me doing it 120 times? How about histogram stretching/colour balancing? Is there a way to batch process or again is it a case of stretching 120 images? I'm still extremely novice at processing DSOs so don't have much experience beyond following a standard workflow. Thanks again
  15. Hey, I captured 120x60s subs of comet 2019/Y4 Atlas last night. I wanted to make an animation of its movements across the star field. I have no idea how to process it. My usual process for DSOs is DeepSkyStacker and Photoshop, and lunar images with PIPP and AutoStakkert. I have no idea how to proceed with calibration files, colour balancing etc (I use a light pollution filter so everything is green). What's the simplest method to process the 120 frames and create a gif or avi? Cheers
