Hi All!
I am currently in the market for getting a new telescope, as I have outgrown my current one (celestron 130eq). I own a DSLR camera already and have been experimenting with some astrophotography (first stage of getting addicted). Over the last few months I have now developed an urge to purchase a telescope that will allow me to take semi-decent deep space photos (Second stage of addition). The crux: I have a fairly limited budged, of around $ 1,000-$1,500 AUD, but I can't seem to find one that fits within the scope (pun not intended) of astrophotography. After doing some research, it seems that the ED80 is a great option, however, I can't find a EQ mount that will not exceed the limits of my budget. If anyone has any suggestions, it would be greatly appreciated.
Disclaimer: I already have a DSLR and T-ring (not included in the budget).

Hi!
Firstly apologies if this is in the wrong section (this is my first post on any kind of forum!) and I'm aware its a question thats probably been asked thousands of times. Please let me know if I should post elsewhere or anything...
So I've made some progress with astrophotography but as much as I try I get so confused with lenses and the specifics so thought I'd ask people who understand them more. My setup so far is a Canon EOS 550d, with a 70-300mm f4-5.6 lens all on a Star Adventurer pro tracker (recently upgraded from an Omegon LX3 mini track). The camera and lens were both second hand and passed down to me so I dont really know how old they are now but I've been getting good results so far (uploaded one of my recent images, still using the minitrack for reference)
Basically I dont know if I'm better off upgrading the camera and sticking with the telephoto lens (from what I can find its a good lens), or would changing to a small telescope be better. If I was to, from what I've found the Sharpstar 61EDPH II would be a good choice?
I've researched a lot and just dont understand the technical side enough to know where I'm better off putting my money. My budget would be around £1000, maybe slightly more for a camera as I do use it for other photography too. Any advice would be very appreciated, sorry for the long post!

I would like to share my fourth image.
With my "lucky week" of imaging, along with M33, I managed to finish also this project. This is my longest integration to date.
These are IC 405 and IC 410, also known as the Flaming Star Nebula and the Tadpole Nebula, respectively, taken over 7 nights, under my Bortle 5/6 home sky.
Total integration time: 18h 29m 00s.
Here are the acquisition details:
Mount: Sky-Watcher NEQ6 Pro
Telescope: Tecnosky 80/480 APO FPL53 Triplet OWL Series
Camera: D5300 astromodified
Reducer/flattener: Tecnosky 4 elements, 0.8x
Guide-scope: Artesky UltraGuide 60mm f/4
Guide-camera: ZWO ASI 224MC
2020/11/18: Number of subs/Exposure time: 41@240s + 1@300s. Notes: L-Pro filter, no Moon
2020/11/21: Number of subs/Exposure time: 48@300s. Notes: L-Pro filter, Moon 46% illuminated
2020/11/24: Number of subs/Exposure time: 48@300s. Notes: L-Pro filter, Moon 75% illuminated
2020/12/07: Number of subs/Exposure time: 15@300s. Notes: L-Pro filter, no Moon
2020/12/13: Number of subs/Exposure time: 22@300s. Notes: L-Pro filter, no Moon
2021/01/10: Number of subs/Exposure time: 37@300s. Notes: L-Pro filter, no Moon
2021/01/11: Number of subs/Exposure time: 18@300s. Notes: L-Pro filter, no Moon
Total exposure time: 66540s = 18h 29m 00s.
Pre and post-processing: PixInsight 1.8.8-7.
This image was particularly hard to process, since there are many bright stars and stretching the nebulosity while taming the stars was quite difficult. I am sure I didn't manage it as well as I would have liked.
Here's a link to the full resolution image: Flaming Star Nebula (IC 405) and Tadpole Nebula (IC 410)
Thanks for looking!
C&C welcome!

I would like to share my third image.
I finally had a "lucky week", since my last session, December 18th. I managed 5 clear nights out of the past 6 (has to be a record, at least for me and my area) and I was able to finish a couple of projects I had started long ago and start a few new ones.
This is M33, also known as the Triangulum Galaxy, taken over 10 nights, under my Bortle 5/6 home sky.
Total integration time: 10h 14m 00s.
Here are the acquisition details:
Mount: Sky-Watcher NEQ6 Pro
Telescope: Tecnosky 80/480 APO FPL53 Triplet OWL Series
Camera: D5300 astromodified
Reducer/flattener: Tecnosky 4 elements, 0.8x
Guide-scope: Artesky UltraGuide 60mm f/4
Guide-camera: ZWO ASI 224MC
2020/11/08: Number of subs/Exposure time: 11@240s. Notes: L-Pro filter, no Moon
2020/11/09: Number of subs/Exposure time: 10@240s. Notes: L-Pro filter, no Moon
2020/11/20: Number of subs/Exposure time: 15@240s + 4@300s. Notes: L-Pro filter, Moon 30% illuminated
2020/11/21: Number of subs/Exposure time: 22@300s. Notes: L-Pro filter, Moon 45% illuminated
2020/11/24: Number of subs/Exposure time: 20@300s. Notes: L-Pro filter, Moon 75% illuminated
2020/12/13: Number of subs/Exposure time: 12@300s. Notes: L-Pro filter, no Moon
2020/12/14: Number of subs/Exposure time: 8@300s. Notes: L-Pro filter, no Moon
2020/12/18: Number of subs/Exposure time: 6@300s. Notes: L-Pro filter, Moon 20% illuminated
2021/01/10: Number of subs/Exposure time: 9@300s. Notes: L-Pro filter, no Moon
2021/01/11: Number of subs/Exposure time: 15@300s. Notes: L-Pro filter, no Moon
Total exposure time: 36840s = 10h 14m 00s.
Pre and post-processing: PixInsight 1.8.8-7.
Image was Drizzle Integrated and then cropped to original sensor size (6016x4016), without resampling. So, it appears as if taken ad double the focal length (768mm instead of 384mm). Image scale 1.04 arc-sec/pixel.
Here's a link to the full resolution image: Triangulum Galaxy (M33)
Thanks for looking!

Made a new video, this is a Astro Systeme Austria specific video, which has direct driven servo motors.
To get them to perform perfectly and be able to track unguided, you have to tune theese motors.
I made a quick video of how the three different methods is working in the "Autoslew" software to run theese mounts.
Maybe this method of tuning mount motors is related to other brands which has direct driven mounts?
Best regards / Daniel
