  1. Thanks Wim. I use a Moravian G2 8300 with Baader RGBs. I’m thinking the number of subs as well.
  2. Every time I've imaged this there is always much more of a blue colour to the galaxy. I tried the photometric calibration this time and I'mnot sure about the results. Granted, I haven't go as many blue exposures as red and green (24 vs 12) and my exposure lengths are 300s. So, would increasing the exposure lengths improve the colour or simply more exposures? I've included a cropped version too. Comments will be very welcomed!
  3. This is a difficult target for me as my house gets in the way most of the time an it's not been great weather in Cyprus. I was going for 6hrs in the Ha but decided to process what I had. So, 2hrs each of 300s in RGB and 3hrs in HA (7nm). Processed in PI, spent ages combining the data in different ways and settled for this in the end. The starless version was created using Stratto - very good software, does it in 1 click. Comments and criticisms welcomed as always - hope you like them. https://astrob.in/336163/0/ https://astrob.in/336164/0/
  4. Good to know I’m not the only one!
  5. Interested to know thoughts on contrast levels and sharpening. I did two versions using LHE, one with kernel at 64 and one at 150. This is the 150 version.
  6. I know this is frequently shot subject but I haven't had a go for ages. This is my take - 16 x 1200s exposures in one night. Processed in PI with a bit more attention paid to contrast with LHE which I think has given this a more dramatic rather than softer look. Comments welcomed as always, hope you like it. http://astrob.in/330276/0/
  7. Back Yard Observatory - isn't this a common abbreviation or have I just made this up
  8. This is an 8 panel mosaic shot in 7NM HA. Each panel consists of 9 x 1200s giving a total exposure of 24Hrs. Stacked in PI and the mosaic was then constructed in APP with processing done in PI. Shot over several nights in January in between rain showers from my BYO in Cyprus. Hope you like it. Steve
  9. This has taken a while to get as the weather, even here in Cyprus, has been awful. I'm fairly pleased with the end result though. So this is an 8 panel mosaic, 3 hours in each panel taken with Baader 7NM HA filter. Processed in PI and the mosaic constructed in APP. Comments welcomed as always. http://astrob.in/328762/0/
  10. Olly, any thoughts on the 8 pos fw and possible vignetting?
  11. I see IK does the G2 with an external but integrated 8 position FW which accepts 1.25@" filters. Does anyone now what the vignetting would be like with this option and if flats would handle the amount?
  12. Two set ups......now thats a great idea.....said my wife never!!!!!! I am thinking about selling the rig to get a new one with external wheel but not really prepared to buy a whole new filter set (just upgraded the marine fish tank).I do love my Moravian though.
  13. I use 1.25” filters, changing them isn’t really an option just now.
  14. Hi, it’s not really the FOV that bothers me,if I’m being honest it’s the hassle of changing filters out!!
  15. No not OSC and by faster I mean the exposure lengths. I do minimum of 20mins in HA which means on a bitty night it can be difficult to get even one exposure (winter in Cyprus).
  16. I spoke to Moravian and they basically said there’s no point in adapting my current camera just for the FW but rather sell it and put the money toward a new one with the larger wheel.
  17. I need some advice.....I currently have a Moravian G2-8300 on my ED80 which is a great camera. However, I don't like the fact that my internal FW only holds 5 filters so when I want to do colour NB I have to change out something. I am also quite liking mosaics at the moment but it takes such a long time to construct them that I am thinking of something faster. My idea was to take the jump into the land of CMOS, possibly an ASI1600 MC and buy a larger FW, funded by the sale of the Moravian but I cant decide if I am being daft or not? I'd like some honest impartial advice please!! Thanks, Steve
  18. What is the best way to construct an LRGB mosaic. I am using APP and have not had much luck with my data recently. I want to know if i should create a mosaic of each colour first then combine them in PI or if i should create separate RGB panels and colour calibrate each panel separately then construct after that? I was having real issues with colour being off between frames. Thanks, Steve
  19. I'm only posting this as I've had a nightmare trying to complete an RGB mosaic of Andromeda. Getting the field illumination matched and the colour calibration correct across the panels (6) was just beyond a joke, especially where the frames meet. I had to shoot an extra panel to fill in a tiny gap between frames too. It has been valuable experience but has shown me that I need to do more RGB shots as I am very much out of practise. So this is the L only of M31, 7 panels of approx 5 hrs each not looking great!!! The mosaic was constructed using APP which i cant fault and some post processing done in PI - I am now moving on from this target and treating it as a learning experience. It doesn't always go right!!!
  20. ?I think we’re agreed it’s a bit odd. Morphological selection but tbh I didn’t really spend as much time as I normally would and I only did one pass too.
  21. Only one pass, but yes I think it looks a bit odd too ?. Like they’re an after thought put in with a very light pencil.
