  1. Hi there nivniv, In my opinion, DSO imaging is possible for light polluted skies but you need to add filters to remove the unwanted light and you cannot expect to capture the very faint detail around some nebulae and galaxies. The LP will simply be brighter that the detail you are trying to image. Reading your posts, I am not sure exactly what you want to do with a scope...you mention earlier that you are interested in DSO imaging but now you also mention interest in Lunar/Planetary imaging. Perhaps you yourself are not sure...an understandable position, I was also unsure when I started. If that is the case, then you should be looking for a good all-round telescope with decent aperture and a focal length that is not too long (IMO less than 1200mm). Other posters have recommended a 100mm APO/ED doublet telescope. This will perform well for both DSO and Lunar/planetary imaging as well as being easier to mount, move about and collimate compared to a larger Newtonian. Might I also suggest you look into local astronomical societies and talk to them. Most societies have observing nights and you can see different telescopes in action and talk to their owners.

    Synguider version 2 issues

    Hi there, Last night was first light for my new Synguider 2, I thought I would post my first impressions and problems with it. I originally used a Synguider 1 and it could guide very well despite not being very sensitive. Here are the problems I came across: - The new Synguider is way more sensitive than the older version, I have to use very short exposures to get a decent brightness level. I worry this will mean I am guiding on atmospheric turbulence rather than the actual drift of the star. - I then found a fainter star (but this was harder to see in the finder-scope). I was expecting to find more stars just pop up on the screen as I increased the exposure time, but this didn't happen. Perhaps I need to play with the noise cut-off settings more to find the point where the background is just being cut-off and faint stars are detected. - Strangely, after I did the auto-calibration, it gave me a DEC aggressiveness of 0, I repeated the auto calibration and I got the same result. So I started guiding and got good round stars... However when I deliberately knocked the telescope to test the guiding the DEC would not come back to zero! How did I get round stars on my 3min subs?! - I actually like the faster refresh rate of the star on the screen, but coupled with the dimmer backlight, the brightness and guiding correction numbers are difficult to read (they change very quickly). So overall, I guess I was expecting the Synguider 2 to be a more sensitive version of the first version but actually, I will need to learn some new set-up techniques before I get the best out of this thing.

    What is this?

    I have seen this effect before (its not that rare), when the Sun is behind clouds sometimes the clouds just adjacent to the Sun in the sky appear as bright or brighter than the Sun itself (at least on the camera sensor). It normally happens when a thicker bank of cloud occludes the Sun (making it appear dimmer) but thinner cloud surrounds it. The thinner cloud scatters the light and appears very bright. Although I can't be completely sure since the photo is over-exposed. As for the reddish colour, I agree with the previous post that it is probably atmospheric dispersion. As a side note for your friend, it this were another planet and this picture was taken during the day, you would expect to see a phase (a light side and dark side). HTH Dan
  5. My ST80 has faithfully guided my scope for the past 4 years. The focuser isn't great but it does lock down quite well. I used some pieces of cardboard to prevent any tilt when using the locking screw. Dan

    Very nice. If you add a Barlow into the mix you'll be laughing!

    AZ EQ6 Alt adjustment bolt

    Is there a way of extending the AZ-EQ6's saddle outwards... I can see replacement saddles but not extensions. You could get one machined, also this would increase the load on the mount quite a bit.

    AZ EQ6 Alt adjustment bolt

    I think you can set slewing limits for the mount. Not done it myself but might be worth looking into.

    Rock painting Messier marathon

    Unfortunately, the Crab nebula turned out to be more of a funky splodge! Also, given my rather poor painting skills, most of the globular clusters will end up looking the same, that's not going to stop me though!

    Rock painting Messier marathon

    Hi all, As I'm sure you are aware, the rock painting craze is going strong at the moment especially up here in Bury and Ramsbottom. My wife and I are really quite keen on it, she is painting Pokemon and I am starting my own Messier marathon. Admittedly, I am just going for a passing resemblance (no plate-solving accuracy here!). Anyone who finds the rocks please take a pic and post to Rammy Rocks on Facebook. Cheers! Dan

    Finally got my 180 Mak and AZ EQ6

    That's a powerful combination Just remember to add counterweights!

    HEQ5 Polar Alignment Help (Newbie)

    Absolutely! I put my camera on live view mode during 3-star alignment and centre it using the grid lines on the screen

    I bricked my Synguider

    That's a good idea, if the new capacitor pops that's the first thing I’ll try!

    I bricked my Synguider

    I've been called worse

    I bricked my Synguider

    Well, I got the Aluminium capacitors (4.7uF) today and I soldered one onto the board. All is working and I have no intention of testing it with the 12V power supply even though it is rated to 50V.
