Hi,

since i started work on my observatory there hasn't been much time for AP, but since lunar photography is done in minutes i had a go yesterday.

Gear:

SW AZGTI with the Skymax127 and Sony A6300 and Baader Neodymium Moon & skyglow filter.

100 frames taken and 50% used to stack in autostackerd.

Very nice image Miguel.

Where is your filter mounted? I ask as I have a 6300 and I can't mount a filter with my set up- my filters are 1.25"

I have the filter mounted on the 2” nosepiece witch is mounted on the T-ring adaptor attached to the camera.

So, 2" filters?

I can't acieve focus with the 1.25" adapter on the noseiece.

Yes, 2”. 

I have no issues with focus, the nosepiece is mounted straight in the visual back of the Maksutov.

Thanks Miguel. Looks like I will have to buy some 2" filters then.

Swoop1, 

what about this

IMG_7387.thumb.JPG.6ae5196af8f0606163116c6be51584e1.JPG

This is how i do it, the difference with the 1,25" nosepiece is minimal.

Is it also a Mak you're using ?

I use a Newtonian- currently a 150mm Skywatcher

So i guess you need more outward travel on your focuser ?

there are extension tubes available, but that would put your camera quite far above your telescope, making it more difficult to balance and you would have more vibration in your image train.

Is this the field of view you have ?

Doesn't seem to bad no ?

There is an option to move the primary mirror further into the tube. You have to replace two sets of bolts (6 in total), and probably get three longer springs, but if you don't mind taking your primary mirror out (simply done with 3 screws), then it isn't difficult. 

I've done it to a SW 1145P small newtonian (that needed quite long , and to my SW150PDS when I fitted a baader cliklock (only an extra 10mm needed for that one).

Ady

- this advice is based on you having a newt. Rereading the thread, I may have got that bit wrong 😉

Yes that is about my FOV with the Barlow.

When I originally started exploring imaging, I had a Sony a350 and bought a T ring with nose piece as a kit. I paniced when I couldn't get focus until I removed the nose piece and screwed the 1.25" adaptor directly to the T ring.

When using the Barlow, I do end up with a lot of focuser tube exposed.

then you also need a barlow, the barlow lens extends the focal point.

      Sunday 30th June.
      NLCs started appearing as the skies cleared around 1.45am.
      Grabbed gear and headed off around 2.15am to the same location as last two sessions. Another 90 shots taken!
      Nikon D3 and Nikkor AF-S 70-200mm f/2.8G ED VR II, tripod mounted, cable release and mirror lock function.
      Lightly processed in Adobe Lightroom and (where required), stitched shots together in Photoshop CC2017
      Taken from north Lichfield (Staffordshire).
      Clicking the pictures should open the hi-res images.
      Panoramic 1 - 7 shots. ISO 200, 2.5 sec, f/2.8, 70mm, 2.56am. Note over in the far right the Pleiades.

       
      Panoramic 2 (Detail) - 4 shots. ISO 200, 2.5 sec, f/2.8, 200mm, 3.01am

      'The Saucepan and NLCs' - Single shot - (Nikkor AF-S 24-70mm f/2.8G ED). ISO 200, 2 sec, f/2.8, 24mm, 3.22am

       
      Started to pack away just as 'Mr Blackbird' started to sing - the dawn chorus broke.... then noticed a beautiful sight over in the East, switched back to the Nikkor AF-S 70-200mm f/2.8G ED VR II and added the TC-14EII 1.4x
      A 7% Crescent Moon.
      Single shot - ISO 200, 0.8 sec, f/4, 280mm, 3.28am

      Yesterday's Moon with the straight wall. Rupes Recta (middle right) and the crater Pitatus (bottom left).

      Dear all,
      yesterday evening, I started observing the moon and sketching crater Copernicus even 15min before sunset. The contrast on the moon wasn't perfect yet, but on the other hand the contrast on the sketching paper was better - no need for LED.  Copernicus with its prominent ray system is wonderfully appearing on the full moon but this time I just concentrated on the 96km crater itself:

      Telescope: Celestron NexStar 127SLT
      Eyepiece: ExploreScientific 6.7mm/82°
      Date & TIme: June 12th, 2019 / 2130-2230 CEST
      Location: home terrace, Dusseldorf region, Germany
      Technique: Koh-i-Noor chalk and charcoal pens on black sketching paper
      Size: appr. 30x30cm
      Looking in my filed skeches, I figured out that I have visited Copernicus five years ago. Here's a comparison of the two sketches showing some changes in technique:

      Clear skies!

      c925 and 294mc pro bin 1  with ir/uv cut filter. 2 panel mosaic best 25% of 1,000 .   Had to convert to jpeg as i keep getting an error 200 when trying to upload a larger file. ( 50+ mb )  clicky for full rez.
       

       
      and a few with the 385c camera with neodymium filter and mostly barlowed.

      So I'm looking for the best grab and go planetary viewing (and maybe some DSOs) telescope that is relatively cheap (below 500$) that will also support some Astrophotography. I know the SkyMax 127 is a Maksutov and therefore has a high F number, but I'm okay with that because I'll just pop on a 0.5x focal reducer to bring it down to F/6 (still a bit high though.) With said Grab and Go I'm interested in viewing Saturn and Jupiter with high detail. What do you recommend?
       
      Clear skies,
      Leon.
      Edit: I need one that'll fit into the Sky Watcher EQ5.
