Lovely image with good focus, flat background and nice round stars.  Very well accomplished indeed ?.

For my own personal preferences, I find the colours in the galaxies a little too cool, with some of the soft yellows of the cores missing. HTH.

Very impressive. That Nikon seems to be an excellent camera and you have captured a great level of detail.

I can only endorse Barry's comments. A great image, really great, but just a bit 'colour cool.'

What a cracker,  nice and sharp,

looks like you have a real nice setup there, with the f3.9 looks very well collimated.

well done.

Wonderful detail, a superb image.  The colour is perhaps a little cool but that is perhaps down to personal taste and easily altered.

      Hello everyone,
      I have a problem, which I thought for long it's normal: after 2-star alignment I enter an object, after the EQ6 finish moving, I should center the object manually ( I do all the process using my phone via synscan WiFi adapter). If I go to observe other object (which I should again manually center it) and come back to the first object I was observing before, I should again center it as first time!.
      Am I skipping anything? Shouldn't the mount be saving my correction and call the new coordinates back if call the object again (at least in the same observing session)? Anyone can help me with it?
      Best regards,

      Having upgraded from canon 1000D to Nikon D5300  how do users of the 5300 find it for Astro I will be using with APT , and how do you take flats as I can’t use Av mode as there is nothing in tools menu to choose no lens ,  do you use in manual mode  and look at histogram ? .

      I thought i'd revisit this one, as i was never truly sure abut the processing originally. 
      So with this one, i sought to improve the stars (they're a big improvement) but also bring out more of the dark nebulosity. Did i go too far though?! Looking at it again today i think i may have. 🤔
      Ha: 7 x 480s, 6 x 1200, 13 x 1200 (a little over 7 Hrs)
      OIII: 9 x 1200s (3 Hrs)
      RGB (with IDAS-D1 filter): 20 x 60s
      The usual Flats & Bias, stacked in APP and processed in PS. 
      Gear used: Nikon D5300 (modded); SW 80ED (522mm FL); HEQ5-Pro; SGPro and PHD2. 
      The original version can be seen on the Astrobin link.
      C&C welcome and clear skies folks!
      ps - At the moment this is still at 100%, but i'll probably end up down-sampling it to about 50%. I don't think it can hold up to 100% tbh. 
      Edit - Here's the new, now much more toned-down, version. It's a clear improvement, so i'll have to keep reminding myself not to try and go for big & bright, when subdued nearly always ends up looking better!

      Original, nasty over-bright version:

      Hi guys
      First things first, apologies for posting this one out of season. A combination of no astro dark, crappy weather, and being busy at work has meant that there's no imaging getting done at all these days. So, i've had to turn to old data to re-process, and this data set was an obvious candidate as i was never happy with how it came out originally. And looking back on it now with fresh eyes, boy did it need it! 
      Nikon D5300, SW 80ED, HEQ5-Pro. 
      3 x 1200s, 2 x 1380s, and 4 x 1500s of Ha
      9 x 1200s of Oiii. 
      11 x 480s with an IDAS-D1, for RGB stars only
      7 Hrs 54 Mins in Total. 

      Stacked in APP and processed in PS. 
      Combined as SHO (using a 70/30 blend of Ha/Oiii for the Sii). 
      The main differences this time were, using Starnet++ to create the starless versions, using more Ha in the synthesized Sii (70% instead of 50% last time), but mostly the improvement has come from toning down the stretch a lot (ok, a heck of a lot!) before making the colour map for the tone-mapping. From then on it was immediately apparent that i'd made a massive boo-boo first time round 🙈
      I've included a 1080p rotated crop too, as i quite liked the framing.
      Feels like ages since i last did any NB imaging. I almost forgot how much i enjoy it! 🙂 

      And rather embarrassingly, here's the original. Try not to laugh too hard! 😂 😂 😂

      Back in early Feb I tried imaging Markarian's Chain, but after 2 subs I encountered guiding issues (a first for me) so had to give up. 
      So just for kicks and giggles, I decided to process them! ? 
      So this is 2 x 10mins. With the D5300, 80ED and HEQ5-Pro. 'Stacked' (if it's even right to use that term!) in APP, and processed in PS. Then reduced to 75% for posting. 
      Why oh why oh why..... I honestly don't even know myself ?
