Had a good night last night:

M101 Pinwheel Galaxy and M66 Leo Triplet

Both 20 x 180s Light, 20 Flats, PHD2 guiding using Altair GP-CAM, Nikon D3200 prime focus

I didn't notice the cover wasn't fully on so the darks were spoiled, so will have to do them again once the temp is down to -1C tonight. This will help the re-processing to reduce the noise and there are hot pixels in there. But I'm happy with the light frames.

Thanks Chris, I need to add the darks so I can stretch the contrast a bit more. There is more data in there, but getting it out without the darks introduces too much noise.

I also need to invest in a light pollution filter as these were a little orange when I started.

This is an example of one light frame:

      Though M101 is a relatively large target it is quite dim and this required a significant effort to get detail into its core. I took 31hrs of 30sec exposures which I then thinned down to the best 18hrs of data. Processed in APP and PS it was tricky keeping the core detail that I had imaged from blowing out.
      Lots of advice and lots of very small curves stretches was the key in the end. Hardly sharpened it much with noise reduction undertaken as and when noise just stared to appear during stretching.
      As the sensor is biased towards red, colour balancing with green and more so with blue was also necessary.  
      Taken at Gain 200 with a UV IR cut ASI224MC uncooled camera, APM107/700 scope on an AZEQ6. 
      It’s a good little sensor if you have the conditions (cold nights) and use Flats, Flat Darks and take Darks every night as the sensor temperature varies being uncooled. For info, I found it ran at about 6 degs above ambient once it was steadily running subs off. 

      Hope you like it.

      I tried imaging M101 here in our Bortle 5 neighborhood and it was sort of tough due to the light pollution but I think I was able to pull off a bit of data. My problem now is that I was able to increase the visibility of the galaxy through stretching but in the process the background noise also increased. I also noticed that my galaxy and stars are a bit orange/reddish compared to the other M101 shots which are kinda bluish in color. Not sure if this is being caused by my astromodded camera but I tried correcting it via Photoshop and this is the best "white balanced" image that I got.
      Looking for some help in this group maybe someone can have a go with my raw file and share some techniques on how to improve my post processing. The stacking was done via DSS and the processing via Photoshop. I also used Gradient Xterminator and also Astrotools.
      Here's my edit and I also attached the raw file so maybe you guys can try tinkering with it also. Also open for any suggestions or comments with my initial edit. Thanks! 😁

      After a day of mixed weather skies looked very clear Thursday 11/3 so headed out around 9pm to take advantage of a moonless night.
      Walking in straight from bright lights seeing & transparency were looking good - double cluster & beehive were naked eye visible with direct vision and some Messier dustiness in Auriga with an averted view.  I had a vague plan to have a proper go at the Leo Triplet & had spent a bit of time on stellarium to plan how to star-hop in via Chertan & L73.  First though I North aligned SynScan on Sirius and Mars (the top 2 suggestions thrown up by the app) & slewed to the the Pleiades to check alignment, which was good. Couldn't resist having a look at the double cluster from there which was so crisp and deep, then via M34 also looking good, to M42 (of course). 
      The Orion nebula was the best I've seen it yet, looking directly at the Trapezium I could see 5 stars & real cloudy swirls above and below, panning upward there was a hint of dust in the running man area, couldn't discern the running man shape, but haven't seen this much before. Moving on up, Sigma Orionis was such a perfect little system & I toyed with the idea of binning galaxy hunting altogether and going after some close Doubles - Sirius even looked quite steady. I resisted as dark adaption was by now starting to work, before leaving the area though I had a quick go at finding M79, a low-down globular in Lepus most of which constellation was just about visible merging into the LP above the centre of town to the South.  I keyed it into the GoTo & was surprised by a short slew to the E.  Looking in the eyepiece I saw...something, very faint, grey glow around two dim fuzzy stars with a hint of  dark lane between, not the expected Globular - checking again it turned out that I had entered M78 by mistake but there it was, a bonus nebula - not visually spectacular but nice to find & fascinating to look-up later.  I made a quick sketch to confirm and tried for M79, but no, far too low by now. 
      I figured night vision was by now good enough to have a crack at the Leo Triplet and took a GoTo to Regulus & centred. I had manually added Chertan and 73 Leonis to the app and duly centred them to get the best possible local alignment.   Putting L73 in the top L of the field I should be able to pick up M66 bottom right. I couldn't be sure so moved in a pattern around & picked up a fuzz patch. Small adjustments gave me a field with two luminous patches to L & R with a star at the top, I couldn't work this out and they were faint enough to be on the borders of imagination. Everything passed behind a bank of thin cloud for a few moments and I used the time to sketch (incredibly roughly) what I had seen so far.  As the cloud cleared away it weirdly helped confirm that the two luminous patches were absolutely real & I gave them a bit more concentrated attention with averted vision. As I did so a third area top R of field made itself vaguely apparent. My expectation management on galaxies is now starting to get a bit more realistic so I let this one sit for a while and added its general position to my sketch. Still baffled by the field related to what I was sure was L73 I made as good a sketch as I could of both the EP & finder fields for later confirmation ( struggling with glasses on/off, red headtorch & not wanting to fire up the bright phone app as magnitude was so marginal).
      I took a last long look and resolved to figure it out with the atlas & app back home. I later realised that what I had done is, after panning around, manage to confuse the star L73 with a fainter close by star (HD98388-apparently) and had absolutely been looking at all three galaxies in the Leo Triplet - the sketch, although crude, gave me no doubt that I had landed in the right spot this time, just the satisfaction was deferred until I was back inside - something I am fast learning goes with the territory of galaxy hunting with a small scope!
      36 Million light years though, a new personal space-travel record
      I moved on to other Leo Messier galaxies & took a quick look at M95 & M96 which I found relatively easily, a dim pair of headlights but no detail, then wandered across to Makarian's chain and marvelled at the sheer number of little fuzzy signatures that wouldn't resolve to points. Concentration was waning a bit by this stage so I decided to save trying to identify precisely what I was seeing to another night when I could be out later and see them higher out of the murk. 
      I finished with the Mak back on M81 & 2 which looked bright by comparison and gave hints of some spiral & shading detail on this night of exceptional transparency - amazing crisp view with them both in the widest field the Mak can deliver (just over 1 degree with a 24mm Baader Hyperion fixed, 63x). 
      As I packed up the scope the naked eye panorama was just fab and seemed after so much dim fuzzy concentration, incredibly bright. I finished with a 15 minute tour of open clusters with a pair of 10x50s that was really stunning. So many stars in the double cluster, the Alpha Perseii , Pleiades, Hyades & Orion's belt just gorgeous  whilst the Beehive lived up to its name like  a swarm of fireflies.  
      Starting to enjoy galaxy hunting for its own sake but for sheer beauty the binoculars had it tonight. A great couple of hours that left my mind in time & space for a long while after I got back.

      I shot luminance for this trio of galaxies in December and after two clear nights in January I managed to get RGB as well.

      M65, M66 and NGC 3628 - The Leo Triplet. Photographed on May 14. Skywatcher 150P with a Nikon D3200 at prime focus. EQ3-2 mount with RA motor drive (no guiding). 
      19 subs at ISO 800 - 30s each. Aligned and stacked in Deep Sky Stacker to give resulting 4min 30s exposure. Processed in Startools to crop, bin, stretch and colour balance.
      This was my second time around to process this image - starting to get the hang of Startools now.
