First post - so I hope I'm putting this in the right place. I wonder if anyone can help? I've got an EQ3 synscan mount which sits on top of a concrete pillar. Despite the Rigid Pillar and good Polar alignment I get terrible Goto's and Tracking. I wonder if upgrading to an EQ5 might solve some of the problems. It seems, from the reviews, to be a much more accurate mechanism. But if I did that is there any way I could buy the basic EQ5 and use my current EQ3 Synscan motors/handset with it. Buying the whole EQ5 with synscan is horribly expensive, and having already got the synscan unit would seem a waste.
I bought a Astromaster 130EQ two years ago and bought separately a celestron xcell barlow 2x and a Xcell LX 25mm. I now use my iphone to take photo's with a adapter.
However, I have trouble finding and specially tracking objects. Will an Goto system make this much easier? The next question is, should i stay with my astromaster 130 mm newt. telescope and invest in a goto mount like the skywatcher eq5 with synscan or can i better take an Nexstar 5SE? I am open for other suggestions
I want to make planetary pictures with my cannon camera (moon / mars / jupiter) if possible deep sky. However there is severe light pollution in my area.
Thanks in advance
I am new to this forum and find this forum extremely useful. I have gone through almost all the threads requesting advice on the binoculars for stargazing and hopefully I will not frustrate someone for this additional thread.
I live near San Francisco, CA, USA and in my early 30s. I am planning a trip to Bryce Canyon in 2 months. That place is supposed have very less light pollution and is recommended for Astronomy/Stargazing. I have bought the Sky Safari 5 android app to get me started into astronomy and hopefully I will continue this as a hobby for a long time to come.
I have decided to buy 10x50 bins and have found few of these below that are in my sub $99.99 range. I am looking for the best value for the $$ in this range. I will be carrying them in flight and will not be able to baby sit them.

The struggles of a beginner learning how to use the equipment. :-)
Pointed mount North and Levelled EQ6 pro mount 8:30 pm Attached wireless release, 2" nose and UHC filter to Nikon DSLR Attached scope and camera, balanced scope for camera use Collimated the telescope -took 40 minutes of messing around Waited until dark. Took the dogs for a walk around the field to pass the time Polar aligned using the mobile app and sighting against Ursa major. Rebalanced DEC for eyepiece rather than camera 3 star alignment. 1st star was way off and took ages to get it in the eyepiece Restarted 3 star alignment. - Selected a star behind a house. Restarted 3 star alignment -complete. Checked collimation using a bright star - perfect (should bloody be after 40 minutes!) Tried to fine adjust polar alignment using a method discovered online (not drift- I don't think I have the patience.) Didn't work. Restarted 3 star alignment then used the polar alignment on SynScan Took a look at Jupiter was great to look at but not what I set out to do, I want DS images... Attached camera Used live view (LV) to try to focus stars Pointed the scope at M3 and took a 2 minute exposure Tried again with a 4 minute exposure SD card failed. Lost some family pics, grrr Now I have to explain to my partner that it wasn't because of Astronomy, these things just happen. Replaced SD card Took some cautious 1 minute exposures of M90 expecting the camera to explode Pictures were faint so moved to 4 minute with a little more confidence telling myself SD card failures can just happen. Noticed star trails Located a bright star Decided to give PEC training a try. Couldn't do it with an eyepiece. Tried with the camera in LV but noticed some gradual movement in the DEC axis. Hoped PEC training would sort this. Moved onto the Spiral Galaxy Took some 2 minute exposures of the whirlpool galaxy. Wireless timer worked flawlessly. Still a little faint so up'd the ISO and took some more. More detail but more noise. Took some darks with the same settings. Packed away while the camera did its thing. Viewed the pics briefly on laptop. There was star trails (DEC axis again and blurring) Went to bed 1:30 am
So what have I learned? Well DEC error was probably due to the balance of the scope being off. I never did re-balance for the camera. I've also learnt today that I should bias the balance slightly East so the gears engage better.
PEC training is a waste of time without an illuminated reticule which I don't have the desire to buy. I'd rather save for a guide scope and guide camera. I've learned I can refine the polar alignment after the 3 start alignment process.
I've also read on forums that perhaps I should manually move the scope to the first alignment start then continue with the usual process. I've also seen that two star may be the way forward for EQ6. So perhaps next time I'll start with a 2 star, polar align using the SynScan handset then back to 3 star with the first manual adjustment.
I should also purchase a few SD cards that are dedicated for Astrophotography and upload them ASAP after the session.
The Astronomik UHC Deep Sky Filter worked wonders with the images for where I live. I can now take longer exposures. Assuming I sort out DEC errors and invest in guiding rig.
