Hello all Just thought I was post a couple of pictures from a complete newbie.  Hope you like them.  http://www.astrobin.com/users/gerald%40evans/ Kind Regards  Gerry

Very nice.

Nice images. My eq6 should be here tomorrow and my 150pds has just been flocked so hopefully can get images this good. Are you using a coma corrector. Did you bother with flats?

couple of great images you managed to get there, what kind of gear did you use to capture them ? if you don't mind me being nosy :)

No not at all! Be nosy! I have a eq6 goto with a Skywatcher 150pds along with a canon 550d not modded. I have no Autoguider just doing my best to get polar alignment. The only other thing I have but doesn't seem to work too well is a Baader coma corrector. That's my kit. Nothing special. So the pictures are ok? To an experts eyes?

You are off to a great start. I especially like the Triangulum Galaxy. Your star shape is a bit off but that has nothing to do with the coma corrector. You will have to put a bit more effort in the polar alignment. All star elongations go in the same direction indicating that the stars are drifting. Otherwise your are well and truly on the right track!

Do you have the Baader protective EOS t mount and coma corrector ring? The three of them are designed to work together to achive 55mm between the sensor and lenses. Other EOS T mounts don't seem to get the back focus unless it's very low profile.

Well i am no expert but once i get my rig all up and together in my obsy ( currently half way through build now ) I would be happy to start getting some images as good as yours :) 

Make sure to post some pics of your observatory. I would like to do that sometime in the future but I've already spent too much!

Yes I'm using a coma corrector. Flats! I'm hardly using darks! I just did a few exposures and 2 darks. They are really the first pictures and I'm learning how to use APT. I wanted backyardeos but you know I couldn't find the download link. If you know send me a link. 

You will love the 150. It's a great scope. Looks the part without being too big and on a eq6 im getting 7 minutes although as someone said with very slight star trailing. 

Autoguider later! Until I've got the maximum out of it.

Yes I have a canon 550d with t ring and baader. Yes I have set it to 55mm from the focal plane.  I'm lucky as a 550d has its sensor quite deep in so I get back focus no problem. I'll look at the baader one though. Do you have a link? Thanks.

Yes I noticed that too but that is after 7 minutes. I don't have a Autoguider. I'll keep going at it and see if I can improve on it. Any suggestions?

For an unguided setup 7 minutes is too long. From my experience, about 2 minutes is the maximum. I've seen in your tech card that you took 3 pictures with 7 minutes each. I would rather aim for 30 odd pictures with 2 minutes. Two minute exposures will improve your star shape and 30 frames stacked will improve your signal to noise ratio.

I have a thread running under the DIY Observatory forum. I totally understand the money side of things as do a lot of other guys and girls on here. getting the obsy up and running is starting to cost a lot more than planned plus trying to get some more astro upgrades :) but hay can't take it with me and sure the kids don't want it lol.

I will definitely give it a try. Thanks!

This is the baader T-ring and the adaptor for the coma corrector.

Get yourself a guiding scope you will never look back.

My newly purchased neq6 and 150pds were put through their first stint last night. Maybe I was lucky but I found it really easy to set up once all the lead had been connected. 

You can even polar align using PHD and I was getting 600s subs that were good enough to keep.

I intend to in the future. I just want to learn all I can with what I have first and battle a bit!

Nice image. You may want to check your spider veins are not twisted as there are a few spikes coming off zeta.

What were your exposure times and what do you use for processing if you dont mind me asking.

Gerry, I can only load one (Triangulum) of your images, but it looks great!!  The stars are round and I can't see much that would disturb me.  Of course I'm not where you are in this learning curve.  Another few months and maybe I'll be where you are today, and ecstatic.  Great going!!

BTW, is it only I who can't get your other photo to load from AstroBin?  Do I have to be a member or be registered with AstroBin.  Triangulum has loaded multiple times but not your second image.

Sorry about that, no idea what happened!  http://www.astrobin.com/users/gerald%40evans/

Yes I noticed that too. I'll check those. For the Triangulum it was 5 x 7 minute frames. I've since learned that without Autoguiding that was too long but the stars are not terrible. The horse head was 27 frames of 3 minutes. The processing I do everything on Lightroom as it's the only one I have.

Gerry,

Great Images!!!  You seem to have this down cold.  I am for sure going to have to keep in touch with you.  I have no confidence that my initial efforts will be anywhere near your results.  Great going.

Thanks! Well I like them. If you do need any help I'm happy to help if I can but there are some very experienced astronomers on here but I'm happy to share what I know. What equipment will you be using?

Should of kept quiet about your veins I have just noticed that mine our out too.

      Finally I have something like First Light with the ODK12. This is just 6 x 600 sec subs Luminance with the Moravian G3 16200 and Chroma filters. Sigma Add stacking in AstroArt 7 followed by a slight crop to get rid of dither edges, Gradient Reduction (As the moon was starting to interfere), DDP and Unsharp Mask.
      Calibration was with Darks and Flats only as I had neglected to do Dark Flats *slapped wrist*.

      Reduced 50% for upload and JPEG. Yes it's a bit noisy, and I think I may have focus issues.
      C&C welcome as usual.

      M33 captured over 4 nights, 16hrs of data using 300sec subs, darks from library, mixed flats for an average and bias frames. Camera: Canon 600D. Everything put into Deep Sky Stacker and the resulting image processed in PS.
      I used a video made by Scott Rosen on processing to help me process and I learnt some really powerful techniques to use in PS.  I think this is my best processed image to date, so I feel happy I have made some progress. Looking forward to reprocessing my old data armed with the new knowledge 🙂.

      Messier 57 is is just coming into a position for a decent look around 11 30 pm. IT is a colourful object and I thought it would give me a good target with which to practice my colour developing in PS/Lightroom. I have read so much about how to produce a LRGB image from the four stacked/calibrated luminance, red, blue and green images,  a lot seems contradicatory and some, when followed, gave me colour yes, but not as we know it. I am sure a fair chunk must be put down to me. Anyway, I now have a work flow which gives me colour, sometimes resembling what other people have obtained. Progess of sorts.
      This images is based on 114s subs at gain 139, offset 21.
      L 39, R 20, G 20, B 19
      Calibrated  and stacked in DSS (flats, dark flats and darks)
      Messier 57 Ring Nebula in Lyra
       

      NASA: M57, or the Ring Nebula, is a planetary nebula, the glowing remains of a sun-like star. The tiny white dot in the centre of the nebula is the star’s hot core, called a white dwarf. M57 is about 2,000 light-years away in the constellation Lyra, and is best observed during August. Discovered by the French astronomer Antoine Darquier de Pellepoix in 1779, the Ring Nebula has an apparent magnitude of 8.8 and can be spotted with moderately sized telescopes.
      Equipment: Celestron 9.25 XLT at F10,  Skywatcher EQ6 Pro GEM, ZWO 1600MM Pro, ZWO EFW with ZWO LRGB filters, QHY5IIC guide camera on Skywatcher 9 x 50 finderscope, Celestron Focus Motor
      Software: Ascom 6, Eqmod, Cartes du Ciel, AstroPhotography Tool, PHD2

      At the same astro party where I shot the Pleiades and partially Iris + the surroundings, I started gathering data for M33.
      For this image I used only a SkyWatcher 150PDS through which I recorded the photons on an ASI1600MMC.
      Curiously enough, I shot ~3.5h of luminance there under Bortle 2 skies, but a simple STF in PixInisght revealed less details than in 4h of luminance (through a LP filter) shot from home under Bortle 6-7 skies.
      Nevertheless, I put all the luminance together, I shot another 40mins of each RGB + 1h45min of Ha and made an image. A bit of colour only I also borrowed from an image I made 2 years ago, but in a small ratio.
