    mono to colour?

    If you mean can you false colour your final stacked image then yes that is quite possible. It is exactly what I do for all my solar images. I don't use Registax but rather use AS!2 followed by final processing in Photoshop. I just convert the the final mono image to a 'RGB' file, add a mono layer and use the 'Tint' function to provide the false colour. Examples on my Flickr page using the link in my signature.

    Absolute newbie

    Hi Ian, if you want to image planets there are several key things. Firstly, focal length. The image scale in the C80 will be far too small for the usual planetary cameras. An SCT or Mak are the scopes of choice. For example I use a 9.25” SCT at a focal length of between 2.3 and over 5 metres. Secondly, and particularly from your latitude the planets are very low in the sky. This introduces the challenge of overcoming atmospheric distortion and you will need a corrector for this called ADC for short. Thirdly you need a fast frame rate planetary camera of which there are many choices. Because a technique called ‘lucky imaging’ is often used it is best to take short video files containing lots of frames. In this scenario tracking becomes less important so a basic tracking mount is fine. If you have a steady hand it can be done manually! The video files may be 30 seconds or a couple of minutes in length depending upon the target and contain up to a few thousand files. There is a planetary imaging section on this forum that is worth checking out. Also, check the web for tutorials on Lucky Imaging of planets, the Moon and the Sun. If you have planetarium software then you can check how the planets are positioned over the next few years. Other than Mars in 2020 it’s not great news I’m afraid. examples of my results are in my weblink in the signature below.

    HEQ5 Synscan Pro issue

    Yes, as above, but is this happening when your controller is set at ‘Rate 9’? If so then it’s likely a fault. If however you have the rate set low, say at #2, then it could indicate backlash in your Dec axis and the mount drive takes a few moments to ‘catch up’. So if you are experiencing a delay rather than a complete failure it could mean you need to adjust out the backlash in your Dec axis. There are online guides on how to do this. Let us know and we can advise again.

    Refractor advice

    Is your DSLR standard or is it astro-modified? You may wish to consider a specific clip-in LP filter depending upon your sky light pollution?

    Small worlds: Mars, Uranus & Neptune in 1 night...

    Very interesting thread. I'm interested to know if you run the C14 at native f/11 with the 290MM or do you Barlow to 1.5x or 2x?

    AZ Planetary Imaging and Field Rotation query

    When I did the transit of Mercury I took ser files every 15 minutes. In that case I used PS to remove the field rotation of the Sun’s disc.

    AZ Planetary Imaging and Field Rotation query

    Autostakkert automatically derotates to a point. All my lunar solar and planetary are done in Alt Az mode. AS!2 can easily deal with a 2 minute ser file and automatically compensate for field rotation. You don’t need to switch anything on in the software. Once you have stacked the file you can see how the corners are adjusted. Just crop the tiff file before further processing to avoid clipping.

    The Veil gets its tail!

    That's crazy. It looks like the Witch's Broom has a shadow imprinted on the background stars. I've never seen such a complete image. Ace.

    A short but unexpected EAA session

    Yes, me too. I have two CMOS cameras but not cooled. I don’t have Hyperstar for my 9.25 though.

    Get Triton

    Yes, I get what you mean. The human brain is capable of integration so what you describe is quite possible. I have put it on my observing list.

    A short but unexpected EAA session

    That M33 has come out extremely well. Just to be clear, is that with the Hyperstar connected?
  12. You would be better looking to swap things around and go for something like a 2” 24mm 82’ EP in that scope. I have one made by Explore Scientific and it was a rich viewing experience with my 12” Dob. I don’t have the scope anymore but use the EP frequently in other scopes. I would have gone longer in fl but age and exit pupil dictated otherwise. i have the Altair equivalent of the reducer you describe but its use is restricted to my Quark EP and my planetary cameras, situations where the vignetting is not an issue due to the small FOV.

    Get Triton

    Mmmmm..... I wonder? It’s billed as 12” distant on Saturday night, my next opportunity to try the new toy. I may even tandem mount it with the 9.25 SCT.
  14. Thank goodness I'm not going. My wallet may have taken a severe beating! Next year I hope to make it.

    Skywatcher Evostar ED150 snaps the Moon

    Yes, I saw that review but I found the stock focuser to be very good, even better than the one on my ED80. I could not get it to slip even loaded up with some hefty kit. Also, whilst using a Bahtinov mask I didn't get any movement in focus when using the locking screw at all. See more detail here:
