How to mount apo on edge 8hd
Astrosharkey replied to Shaun Sr's topic in Getting Started Equipment Help and Advice
ADM do a kit that would do the job, but it is a long dove tail, i mounted my guide scope this way https://www.firstlightoptics.com/adm-mini-dovetail-series-mds-kits.html I dont think mounting like the finder scope would be rigid enough for the weight of an 80 but i may well be wrong- 1 reply

Which Lenovo is it, I have a t420 (all usb2) and a t430 (2 usb3, 1 usb2 and 1 powered usb2)

I have a Pegasus V1 fitted to my 80ed, I mounted it on a longer dovetail which does move weight back a bit but offset it with a counter weight up front, never had any issues and use it remotely via sharpcap

Which camera settings are relevant for darks/bias cali frames?
Astrosharkey replied to Revs's topic in Discussions - Cameras
I use an offset of 50 for all my imaging, tried 30 but it clipped so now just stick to one setting for all -
Which camera settings are relevant for darks/bias cali frames?
Astrosharkey replied to Revs's topic in Discussions - Cameras
I keep everything the same for all settings, and use -10c for all my imaging. When I make a library i take 50 frames with the cap on in a dark place, all the same cables in the same ports and then when i process my first image with the darks let DSS stack them into a master frame. I have a set for 350 and 500 gain (but that is my camera) and a range of exposure times that I might use. -
I use one of these with extra lead attached to get balance on my scope https://www.firstlightoptics.com/counterweights/baader-dovetail-bar-levelling-counterweight.html

Telegizmos covers, I have a 365 and leave my mount and scope out for weeks at a time, waterproof and thermally protected as well

Anyone tried the combination before I possibly toast something??

Yep, its a different world, much easier to use and a wide field for those bigger things out there (with my camera I get 2.5 degrees fov), no use at all on plantery or the moon really, but things like the rosette and California nebula just pop, although that said I am waiting to get outside and start setting my new edge 8 up to get back in close again, just remember no one scope does all

How can I improve my seeing conditions?
Astrosharkey replied to WilliamAstro's topic in Getting Started With Imaging
Only use the best frames not all of them, I tend to stack with autostakert and you can see what % of frames are good and only use those -
What else do I need for my 55mm backfocus?

https://www.firstlightoptics.com/adapters/baader-t2-extension-tube.html 7.5mm and 15mm together = 22.5mm -
First AP Rig...
Astrosharkey replied to Tenor Viol's topic in Getting Started Equipment Help and Advice
HEQ5 and camera bodies all sound good, cannot comment on the scope as don't know it, get your basics sorted first, accurate Polar Align, learn the mount and you should be good for 30 sec subs to start with, when you are confident you can start adding guide scopes etc. I am also a Mac user but after lots of looking around for software etc (I now use PHD2, Sharpcap, ASCOM filter wheel and focus unit, DSS, Photoshop, registack, autostackert, pipp etc etc) I found it easier to get a second hand windows 10 refurbished laptop for putting out in the cold and damp with all the free software and monitor it all via chrome remote viewer on my Mac from the sofa! Not a purist in the slightest but even at the observatory means I can sit inside with a warm drink during the hours of imaging. -
Skywatcher Refractor Autofocus Upgrade?
Astrosharkey replied to David Smith's topic in DIY Astronomer
I have a Pegasus focus cube fitted to my 80ED and works a charm both in and out of sharpcap -
Help with Beginner Astrophotography Setup
Astrosharkey replied to Ryan Adams's topic in Getting Started With Imaging
Nexstar is an Altaz mount and although fine for moon and planets will not really do the job for long exposure long duration deep space photography, the eq5 will achieve but ideally you want the HEQ5 as a minimum (I started with an eq5 goto mod)- 17 replies

What to buy as a 1st Astrophotoprahy setup ?
Astrosharkey replied to Kenboy's topic in Getting Started With Imaging
I started with a second hand 200p and eq5 with loads of bits and bobs, quickly modified it to GOTO, followed by filter wheel, cooled camera, guide scope, new telescope, then new mount! Good luck, you cant go wrong with the 200p to learn with, robust, easy to use and a good learning tool, but expect to start acquiring more stuff. It can be problematic in any kind of breeze due to its size. -
I use the mono version of this in my guide scope with no issues, was originally bought as a lunar / planetary camera and repurposed

Scope balancing WO 71GT
Astrosharkey replied to Martthebass's topic in Getting Started With Observing
I had the same issue with an 80ED, I got a longer dovetail and extended it forward then ended up with a baader clamp and counter weight, I recently switched mounts which moved all the weight back again so ended up adding another counter weight and 2 kg of lead to get it to balance (I cant move any further forward because of an auto focuser fitted. -
Scope to get started with deep sky AP
Astrosharkey replied to JoshHopk's topic in Getting Started With Imaging
I started off with a 200p and last year switched to an Ascent 80ed Frac (about £390) and added a reducer / flattener and have done all my imaging with it since, at 80 its very wide with my camera (about 2.5 degrees) so good for the large stuff (but not great at the small stuff). It always worth using the astro tools FOV to play around with possible scope / camera combinations to see what you can achieve -
Yep, love them I will PM you a link to my Flickr and you can look at what I do

Can it wait 15 years till I finish my current job, local and already know some of you lol

I never had enough out focus with my Newt, just use an extension tube or a parfocal ring on the camera.

I have had a CEM60 (Non EC) for about 6 months and love it, Yes you do end up with a single cable going to the main camera (but I would do that anyway as I guide and don't like two sets of pictures trying to go down the same wire). The USB 2 hub gets filled anyway with the guide camera, filter wheel, focus unit and mount control as do the 2 power outlets. I regularly get guiding down at 0.3. It is a beast but I cant see myself changing it till my back gives out (and that will hopefully be a few years away yet.
