  1. Thought I would have a crack at Venus with my Dob (no tracking), I believe this is referred to as "lucky imaging" ?

    2x barlow on the 178MC. I allowed the planet to drift through the field of view and captured 200-300 frames using ASI Cap.  I repeated this until I had around 3000 frames made up across many individual AVI files.

    I joined the AVI's together then used PIPP (best 2000 frames), AS, Registax and Paint.net to produce the final image.

    I was quite surprised at how it came out, and was a fun thing to do.

    Thanks for looking 🙂

  2. i have just downloaded and installed this onto my astro laptop. Will have a play next time i get chance. The interface certainly looks very simplistic and less cluttered than something like Sharpcap, not sure if this will affect just how good or bad it is in comparison, but im up for having a play with it.

    Thats great. I also use an altaz mount and am always concern about taking more than 2 or 3 minute movies of Venus due to field rotation. I hope the weather improves soon so I can try with sharpcap (focus and ROI) as you did (but with my IMX224 colour camera).

    Thanks for the info,

    I don't think its field rotation as such you need to worry about with planetary imaging. Its the rotation of the planet itself as far as I know. I always thought a couple of minutes was generally "optimal" for planetary work but I may be wrong, it was certainly the case when I got my first scope and modified web cam to have a dabble with.

    With my camera I tweaked the settings and used the ROI at 800x600 along with using the RAW8 setting it enabled a framerate of around 90fps. So a couple of minutes captured lots of frames. My astro laptop only has usb 2 also so perhaps with a newer laptop I could have achieved an even higher fps, not sure. 

    I intend to have a crack at venus with my 90mm mak just for comparison with the 127mm one, hopefully during the next week or so.

  4. Thought I would have another crack at this.

    127mm Mak, ZWO178MC on my AZGTi mount, 2x barlow. 

    The seeing wasn't the best and the whole planet seemed to be shimmering and bubbling but I persisted anyway.

    I had a bit of a play with the focussing assistance in Sharpcap to see if it helped.

    I also used the ROI feature in sharpcap to get a higher framerate and managed 10000 frames in a couple of minutes. I used PIPP to get this down to around 4000 frames, then AS, Registax , Gimp and Windows photo editor.

    Not in the same league as some of the spectacular Venus images in here, but something nonetheless.

  5. I bought the APM 1.25 wedge fairly recently. I have only used it twice so far on my 72mm scope. 

    I would say the granulation was more noticeable than a solar film filter. Definitely more texture visible even with my small scope. 

    Need to hook my ZWO 178 up to it to check how much better the images may well be.

    Makes a great telephoto lens with a DSLR as well.   

    I sold mine,  and sort of wish I hadn't, even though I've  got  (n+1)**2 other scopes as well.

    TBH the scope is literally brand new. It was too good to miss at £50.

    Will give it a go on my DSLR at some point

    I did notice that I couldn't fit the entire moon on the sensor of my 178, even with a 0.5 focal reducer attached to it. lol

    Not to worry, guess I will need to learn how to do a mosaic and stitch it together. I am sure that my 127 mak can fit the whole disk on the sensor of the 178 although I do realise that the focal lengths and f ratios of the two scopes are different I believe.

  7. I bought myself a 90mm Skywatcher Mak recently. I have no need whatsoever for one, lol. But the seller only wanted £50 and it came with a bag, red dot finder, two eyepieces and diagonal. All still in their plastic bags and boxes, the red dot finder still had the plastic to pull out from the battery before use, and there were no marks at all on the dovetail even. 🙂

    Anyway, I had a quick look at the moon last night and then thought why not try it with the ZWO 178MC and focal reducer just to see what I could capture and for a bit of fun.

    This is the result of around 8 or 9 minutes of 15s images livestacked in sharpcap and processed in Startools.

    I like that composition

    Thanks. I had to crop a little bit from the edges due to stacking artifacts. But this is pretty much framed as I saw it on the laptop screen. 

    I think there's another pass tonight. More directly over/in front of M45. 

    I won't have an opportunity to capture it tonight tho. 😞

    Managed to bag a few other targets too. Not processed yet.

    A good effort, not seen star flares like the brighter ones before. 

    I think they are created by the aperture blades in the lens. I stopped it down to f5.6 I think. Not sure if they would be minimised by stopping down further or not. 

    Personally I've always liked them. As I do diffraction spies where people have used Reflectors for imaging.
