GazAstro Posted April 21, 2021 Share Posted April 21, 2021 (edited) So, I finally got round to trying my C8 Edge on the (Darkframe tuned) HEQ5 ! It's been a roller coaster journey but I'll leave that for another time. This is my first time imaging at 1400 mm so quite a challenge, managed a mere 25 mins of L in 15 second subs @139 gain and 20 mins each of RGB in 30 second subs @ 139 gain. Darks = yes, flats = no, massive amounts of stretching in Photoshop = yes (binned) resized in Photoshop to give more acceptable pixel scale 🙂 I know it's about 3 hours short of data and incredibly noisy / rushed but I was so pleased to capture anything with this set up. Looks way nicer on a mobile phone 🤣 Guiding was 0.69 " over a 2 hour period with some really good spells as can be seen below. Thanks for looking. Off to research ways of adding L to RGB now - did this one by using lab colour and pasting over lightness channel.

Padraic M Posted April 21, 2021 Share Posted April 21, 2021 Looks good! Stars seem fine to my eyes. Are you guiding through OAG or guide scope? You'd be happy with 0.69" on a HEQ5 - I've finally managed to get mine guiding consistently around 0.75-0.85", which is fine for my current pixel scale, but I also have a C8, which I intend to use shortly, and which could be a challenge.

GazAstro Posted April 21, 2021 Author Share Posted April 21, 2021 Cheers Padraic, using the OVL thin off axis guider. Stars are terrible on it but it works 🤞🏻 Quote Link to comment Share on other sites More sharing options...

Looking good for so little data, a few more hours will work wonders on it. The best way to incorporate Lum into the RGB data, is to drag the RGB data as a layer into the Lum image. Make sure the Lum image has been changed to RGB from grayscale. Select the RGB layer, then change the blend mode to color. More tweaking will probably be needed on the saturation etc. 1 Quote Link to comment Share on other sites More sharing options...
MarkAR Posted April 25, 2021 Share Posted April 25, 2021 A good start with the C8, more time and tweaking your set up and you'll be well away. 1 Quote Link to comment Share on other sites More sharing options...
