Mounting star adventurer on tripod?
DorsetBlue replied to Nerf_Caching's topic in Getting Started With Imaging
A lot of tripods have the option of unscrewing the ball mount from the top, just leaving a larger screw (my Manfrotto did). The SA comes with a screw in adapter on the base for the smaller ball joint screw, this can be unscrewed to convert it to the larger size for direct mount on the tripod. -

I have one of those and have successfully used it for some astrophotography. Focus is an issue though and difficult to counter, as the primary is fixed. -
Imaging with a Star Adventurer
DorsetBlue replied to M Astronomy's topic in Getting Started With Imaging
No, it can only drive in one axis and that is at guide speeds - not slew speeds. -

Hi, I cannot find a Yongnuo 200mm f2 lens, they seem to stop at 100mm? -
There is always the option of piggy-backing a DSLR on the Mak.

Yes, I think it was. The tracking improved towards the end of the capture run, where I suspect it moved away from the zenith slightly. I suspect I might have been a bit viscous with the colour module in StarTools.

Had the Starsense equipped SW130P/Alt Az setup out last week and had a go at M51 and M81/82 - pretty happy with the results, although the tracking on M81/82 was a bit erratic, hence the short exposures: M81/82 - Best 67 exposures of 10s - stacked in DSS and post-processed in StarTools. M51 - Best 15 of 60s exposures (cloud came in and I lost a lot) - stacked in DSS and post processed in StarTools.

Need less cloud first lol. My SS had the new USB port connections, so I have a USB-Serial converter built into the handset. This apparently simplifies the connection greatly (it did for the Firmware update) but we will see. The SS is currently connected to a bitsa (i.e. Astroboot special) SW AltAz BTW.

I believe you can but I haven't tried it yet (only just got my Starsense for SW kit).
-
Yes. Although to be honest, and being in a similar situation to you, I would probably customise my existing 130p for prime focusing with the DSLR if you are going to use it purely on a AZ Synscan. I assume it is the 650mmFL 130 and not the 900mm FL?

I cannot use prime focus with my existing telescopes with the DSLR (but do with the GPCAM), neither have sufficient inward travel.
-
Not as impressive as some others here but below are a couple quick experiments I did with a basic setup Monday night. Both taken using a Canon 100D, prime focus via a T-mount 2x Barlow on a SW 100 Heritage Reflector (yes, the little Dobsonian) mounted on a SW SynScan AltAz mount. Both 10x 30s exposures at max ISO and then stacked in DSS and lightly processed in StarTools. M31 M92 A little soft on focus (I was in a hurry, experimenting with my GPCAM v2 at the same time).

That app is certainly quicker than opening my clock app on the phone for the exact time - very useful. After a few months with mixed results from my bitsa (made from bits from Astroboot) Alt-Az Synscan, I thought I would include the following: 1) Yes, level is very important but I have had good results from the built in spirit level. 2) As my mount did not come with a telescope, I was using my SW 130P (900FL) that came with my EQ2. I think this scope is pushing this mount to its limits, mainly due to the length. I have just tried my little SW100 Heritage reflector on it and it is much happier. 3) Make sure the alignment stars you use ARE actually those stars, even with a 25mm Plossl this isn't immediately obvious. This was one problem I had last night *SLAPS FOREHEAD*. 4) My mount does not immediately start to track accurately on GOTO. Last night, I had to "tinker" with the position on the handset for a little while before the tracking settled down each time (yes, this was some time after the confirmation BEEP). 5) My home position is indeed flat and North (although I am not sure if this is required or not). Although I have a great urge for a Celestron Evolution, I think this mount will keep me going for a little while yet.

If you are bothered by the refraction spikes, have you tried using the ST Heal/Synth modules (not tried them personally, as I have been using my DSLR lenses up to now)?
