I'm a Finnish noobie trying to learn. I got my first telescope in the early June, but the skies have been too bright to get a good look of anything.

My latitude is 61.469713°N, which probably explains...

BTW, is there a way to get help with the forum SW itself? I'd like to have a lighter background. Would be easier to read.

 

Moi! Wishing you luck when winter comes....hopefully not too many snow clouds! I am often in Jämsä and never have much luck!

I had a Meade LX90 and bought a wedge for that to try astrophotography. It was a nightmare (not because of the 8"SCT), but it added extra time to set up and the wedge itself is a an extra heavy lump of metal to cart around. A wedge might be suitable for a permanent installation, but if like me you have to set up each time, it just extended the whole process of getting ready- upwards of 40minutes and getting the polar alignment correct was always a challenge.

I now have an AVX with both a 80ed ds pro and an 8" EdgeHD, which I've owned for just over 12 months. I've not encountered any of the heartaches @Waldemar refers to, although I have only just started down the AP route - maybe that is something I will discover this year. There have been various upgrades to the AVX over time (mine is a 2019 version) and certainly the earlier versions had issues. For me, the AVX gives me the right balance of portability and performance - anything bigger would not be used without a permanent observatory. I have starsense and an ipolar which make setting up much quicker.

The most common  mount I see recommended on here for AP beginners is the Skywatcher HEQ5-PRO, and the nice thing about that mount is that there are options available to upgrade its performance at a later date (which does appeal to the inner geek in me, and maybe I would have bought one instead of the AVX had I been reading here first).

Thanks for this. great to hear about your experience of having actually used one. Like you I have to setup every time I want to use it, so it sounds like the wedge would be a PITA! Appreciate the feedback!

Before even thinking of starting to do ap with a SCT mounted on an AVX, please buy this book: "making every photon count" 
it will save you money, frustration and heartaches.... The AVX is a nice mount for visual, not for ap.
Same goes for the C8, very nice scope, but because of the long fl, very skill demanding, not really suited for beginning imagers, so: bad combination...

A better combo would be for example an ED80 refractor on a CEM25.
Of course many other combinations are possible, but you are sort of thinking about the most demanding one...

In fact an EQ mount is kind of a 'must' for ap.

Many thanks for the recommendation! I’ve not heard of this book, so will definitely check it out!

Which mount did you get with the Celestron Nexstar 8 (and is this the C8 SCT?) The popular entry level SE mount is not suited for astrophotography, wedge or no wedge - there is too much wobble and backlash.  A lot of people buy a SCT and wedge with the intention of doing astrophotography, find out the hard way that this was a bad idea and either sell up the whole outfit or buy a german equatorial mount.  Indeed I have seen it written that this is the reason that SCTs are often surprisingly cheap second hand....

One issue quoted is that polar alignment is such a pain that you would only willingly want to do it once and leave the outfit permanently set up.

Hi, I actually miswrote that. It's the Nexstar Evolution 8, which comes with the standard Computerized Altitude-Azimuth Single Fork Arm. I didn't realise that the polar alignment could potentially be more difficult with a wedge. I've watched a few Youtube videos where this didn't come out. I guess unless there is much improvement between the SE mount and the Evo mount, then perhaps a wedge is not the way to go and Eq mount. Appreciate you taking time to respond.

Hi all,

I've recently got some time back in the evenings (kids are growing up a bit), so I've started heading out and have the bug back for getting back into astrophotography. I've very much an amateur. My kit list at the moment is Celestron Nexstar Evo 8 and Nikon 3500. I'd like to do more deep space photography with longer exposures. 

Ideally I would just buy an eq mount such as the Celestron AVX but I am also tempted by the HD Pro Wedge due to the lower cost. I've spent a lot of time on the forums to understand what the general opinion and and it seems to be mixed. What I don't want to do is buy the wedge and find that I have a load of issues that would haven't been evident if I'd just gone for the EQ mount to start.

Any advice appreciated!

Kind regards,

Firoze

Better than your back garden though?

A much better view as Ditchling is high up. I'm planning on heading to Pulborough next.

Wouldn't the city lights of Brighton reach Ditchling Beacon. I'm not from that area so i wouldn't know. 

I was there last night. I have to say I was a little disappointed. There was far more light pollution that I expected. It didn't help that there is a football stadium with it's flood lights on all night!

This is great Dave. Thanks very much! I am certainly going to head down to Birling Gap sometime. I've visited during the day and thought it could be ideal. Ditchling Beacon is certainly an accessible option! Many thanks, very much appreciated!

Hi there all,

I've not been on a forum or actually had much time for any viewing in a couple of years now (young kids), however want to start taking my scope out again. Does anyone have any good locations around Crawley that they wouldn't mind sharing? I've been over to Devils Dyke recently and Ashdown Forest a little while ago. Any other suggestions appreciated!

Kind regards,

This was my first attempt at Orion's Nebula whilst in the desert of Abu Dhabi. Used a Nikon 5200 with Nexstar Evo 8. Would like to try stacking next time. Any feedback appreciated!
