  1. Thanks, I live on the edge of South London so it's ok as long as the target is pointing South! Anything above 45 degrees North is also ok but then restricted to narrowband
  2. Thank you. Sorry should have put that in when I first posted - I've updated my original post above with the details
  3. The Horsehead Nebula in Orion. This is one of the first deep space objects I saw in a book as a child and it captured my imagination - I’ve been intrigued by this incredible Universe ever since. As a small child, I’d have been blown away to think that 40 years later, I’d capture this image from my own backyard. I've only been astroimaging for less than a year so would appreciate any constructive comments/ criticism. Higher resolution version at: https://astrob.in/393553/0/ I tried something different with this image as I was severely restricted by time and conditions - battling last months full moon and a small cloud free window of about two hours each evening where the Horsehead appeared between some large trees and the edge of our house! I took mainly Ha because of the moonlight but then blended in some Lum and Blue data to one master image. This brought out more detail in some of the nebulosity. The resulting Master was then processed through the red channel only in PixInsight and Photoshop: Ha 36 x 240s Lum 25 x 60s Blue 20 x 60s Scope: Altair 130ED Triplet Mount: Celestron CGX
  4. Lots of cloudy nights lately so revisited my first efforts with the ZWO ASI 1600 from back in October. First go at narrowband and captured about 4 hrs each of Ha, Oiii and Sii (60 x 240s each). Had a few problems with guiding but overall quite pleased with the result. Equipment: Altair EDF 60mm, ZWO ASI1600 Camera, Celestron CGX Mount.
  5. I've recently moved to the ASI1600 from a DSLR and still struggling to get to grips with it for LRGB (longer narrowband seem to be ok). At unity gain (139) the exposures in LRGB come out about 5-10 secs for a correctly exposed histogram. I agree re the number of images this means stacking and haven't quite got my head round it yet. Maybe I'm just doing it completely wrong, which is likely. Have you any experience of theASI1600 and any recommendations. I'm using SGPro fro the image capture....
  6. This is probably a dumb question but I thought I'd pose it anyway. Using the ZWO ASI1600 on some of the Orion targets and with Unity Gain the exposures needs to be between 5 - 10 seconds when using standard LRGB filters. As long as I'm polar aligned, surely the mount will track sufficiently in this time frame without needing guiding corrections from PHD? I'm also thinking that guiding could actually make my images worse as the correction in each exposure would be much more noticeable as it would be a higher proportion of the exposure time - effectively nudging every image? New to this so any thoughts from the experst appreciated...
  7. Had another little play with this image after feedback...
  8. Tom said "Thank you but what am I supposed to do with the SNCR?" Images were captured on his Canon 750D which is unmodified. He took about 60 Lights and then calibrated and integrated 42 of the best in Pixinsight along with Darks, Bias and Flats. Lights were 42 x 300s at ISO1600.
  9. Thanks, I helped with getting the autoguiding set up and focusing but the rest is down to him (and YouTube!).
  10. Thanks, so far he’s been following lots of YouTube Videos, presumably there’ll be one for that as well. Just need to get the PI process flow from him so I can have a go at a few of my more pathetic attempts...
  11. Hi, I helped my 15 year old son to capture some images of Andromeda during the summer. Images were taken on a guided Skywatcher Esprit 80ED using his unmodified DSLR. He's been processing the images in Pixinsight whilst learning to use it - with more success than me so far! He wants to use the image as part of his GCSE Photography exam next year and asked if I could post the image up here for comments. He wants to know if there are areas he can improve so looking for any advice that's out there.....
  12. Looking at a simple and tidy solution for all those cables. I know both are expensive but would be good to hear from people with experience good or bad from either system. Or anything else worth considering?
  13. Thanks Carole, since posting this I've been in discussion with a couple of retailers and one of them has suggested I have another look at the Sky Watcher Esprit ED120 - as I already have and like the ED80. Noticed you've got one of these, how have you found it?
  14. Thanks very much, will try and find out from the retailer if there are similar issues on the larger scopes....
