  1. Looking for a camera mainly for Solar/Lunar work. Equipment will be a 4" F7 refractor,and a Daystar Quark,which will push F-ratio to around F30. Will the ASI 120M be a suitable option? (i use that for guiding at the moment). Failing that,i have been looking at the 174M,178 and 290.But not a clue which would be best! Regards, Sooty.
  2. I just have a basic Skywatcher Crayford focuser at the moment Pete. It's the 2nd one i have brought,after managing to 'break'the other trying to fit a motor focuser to it. I'm very reluctant to try again.lol Sooty.
  3. Taken with a Mak 180.and asi224c. On the look out for a ADC,although most places seem to be out of stock at the moment. A autofocuser would be a godsend,but struggling to find 1 for the the Mak. Sooty.
  4. Just purchased the the above camera,and intend on using it with Sharpcap. Can anyone familiar with this camera give me a few basic settings? I’ve read unity gain is around the 120 mark. Also,am I right in thinking that with it being a cooled camera,I could start building a dark library within the comforts of the house? Thank you in advance. David.
  5. The 115 triplet is very tempting,at around 8kg, + finder guider,reducer and hypercam,should just be within the limit of my mount??.Although the 102 at 5kg will pose no such problem,easier to handle and guide.Will sleep on it me thinks! Thanks all for the replies. Sooty.
  6. Hmmm. Just as i'd narrowed it down to the Skywatcher or Altair! You've got to love this hobby at times like this! lol Sooty.
  7. Personally i'd rather have a refractor,but thats just me.Haha. I'd looked at the Skywatcher Espirit 100 ,and also the WO 103ED, Altair Astro 102 triplet. Obviuosly galaxy imaging is very demanding of the mount,but was hoping to maybe catch some of the fainter ones. Sooty.
  8. The camera i use at the moment is a Altair Astro 183C hypercam,the fan cooled version,but eventually/hopefully,the Pro version,which i could then set the cooling point.I also have various Nikon DSLR's (D300S.D90,D7200),as my other hobby is Aviation photography. I'd say im in a average light pollution area,and use a moon and skyglow filter at the moment.Still waiting for the weather to clear up before i try a UHC filter.Also,at some point in the future,id like to try Narrowband. Main interests are Galaxies,the wide field images i use a D90/lens combo. Sooty.
  9. Currently imaging with the above scope (and pleasantly surprised with the results),on a HEQ5 Pro. My imaging time due to houses,trees,hedges etc is around 2.5hrs if im lucky! Therefore,am i right in thinking a faster scope would enable me to catch more data? The ED80 is around 6.4 with the reducer fitted. If so,any suggestions? Budget around 1500 max. Bearing in mind the imaging weight of the HEQ5 is around 9kg depending on which site you read! Regards, Sooty.
  10. Hi.Yes,debayer ticked in Registax. Hoping to get a half decent image of Saturn,before the trees block my view. David.
  11. Hi all. When i try to stack my images in Registax 6,the final image has no colour to it at all. I capture the frames with Sharpcap (latest version) and a ASI120MC camera. The original picture shows some colour, but alas, the end result is rather disappointing. Settings were [ZWO ASI120MC] Debayer Preview=On Pan=320 Tilt=240 Output Format=AVI files (*.avi) Binning=1 Capture Area=640x480 Colour Space=RAW8 Temperature=26.7 Discard Split Frames=Off High Speed Mode=On Turbo USB=68(Auto) Flip=None Frame Rate Limit=Maximum Gain=32 Exposure=0.1 Timestamp Frames=Off White Bal (B)=53 White Bal (R)=73 Brightness=2 Auto Exp Max Gain=50 Auto Exp Max Exp M S=30000 Auto Exp Target Brightness=100 Mono Bin=Off Apply Flat=None Subtract Dark=None #Black Point Display Black Point=0 #MidTone Point Display MidTone Point=0.5 #White Point Display White Point=1 TimeStamp=2018-07-06T21:10:23.9394231Z SharpCapVersion=3.1.5193.0 Thanks in advance. David.
  12. Cheers for that. I use the Altiar Hypercam 183C for DSO's in RAW16. With RGGB debayering selected. Will try the same with the 120MC. David.
  13. Thanks. Will hopefully get time to try again sometime this week. David.
  14. I'm sure it was RGB24,alas i didn't save the settings. David.
  15. Beast 10% of 2000 frames stacked in Registrax,captured with Sharpcap. Not used the 120MC before,and after a few attempts,with the laptop crashing/freezing/blue screen of death etc,managed this image. Any advice on how to get rid of the 'grid lines'.Also,i read somewhere that there is a maximum time limit for imaging Jupiter,due to it's fast rotation,i think it was 2.5 minutes? For some reason the lines don't seem to appear on this image! And the the focus could be a lot better. Regards, David.
  16. Sorry for the confusion,i have had the mount a couple of years now,normally with a Mak 180 on it. I got the ED80 at Xmas,so i could try some imaging.The mount has been re-located on a permanent pier,hence the rough polar alignment.Still got to get the ST80 and GPCAM to work with each other,then try guiding with PHD2.Well,that is the plan anyway.haha. Sooty.
  17. 20x180sec exposures,with around 12 dark frames.Just a quick polar alignment,as i couldn't wait to try it out! Doesn't help with there being a street light in the vicinity,but thought i would give it a go.Was rather hoping for something a little better.The mount is a HEQ5/ED80 Pro. Sooty.
  18. Thanks guys.Thought it was just me! I've just got the free trial for Alignmaster,so expect it to be cloudy for a while.
  19. I'm unable to find any links to Astro Baby's tutorials! Just keeps coming up,Error 404,page not found. I followed it a few years ago,and was happy with my polar alignment,have since re-located my mount, and not 100% sure how i did it. My mount is a HEQ5 Pro Synscan. Thanks in advance.
  20. Success at last.Have managed to get the ED80 and ST80 to focus on the Moon,and marked the focus tube for future reference.I then got some of M45 in the eyepiece with the ED80,GPCAM in the ST80,where it will 'live' for the foreseeable future.I then started Sharpcap but couldn't see any stars.I'd read somewhere,that stars should show,without having to alter the focus??.I presume it must be something to do with the settings,but didn't know where to start!.I then opened up PHD Guiding but nothing showing there either.Any advice regards settings for either,will be greatly appreciated. Regards, Mitt.
  21. Thanks for that.So,something like this? http://www.rothervalleyoptics.co.uk/antares-125-extension-tube-2-long.html Mitt.
  22. Thanks for the replies all. Doesn't look like i will be guiding any time soon then. Was rather hoping to try my PA with Alignmaster. Regards, Mitt.
  23. Hi All. I'm really struggling to get my Altair Astro GPCAM (colour) version,to focus with the ST80. Have tried with and without the supplied 45* diagonal. Do i need extension tubes,do you think? Regards, Mitt.
  24. Cheers.Will have a go,if this fog ever lifts!
  25. Thanks for the link. Am i correct in thinking that i can take some shorter exposures and use the original saved Tiff file? David.
