I'm considering the 250PDS. The main use is visual, and the second is EAA (I currently use a zwo183mm).
What I'm hesitant about is the primary focus. since It's mostly for visual, I'm wondering on how much back focus it has compared to the standard Skywatcher 10" dobsonians? with the standard dobsonias with the same optics and focuser you already need an extension tube for most eyepieces...
Also, there's probably a "bigger" obstruction (bigger shadow on primary)?
I have a SkyWatcher AZ-EQ5 mount. It’s all working fine, except I have an issue with alignment. This applies whether I’m in EQ or Alt-Az mode.
I set it up using one or two star align without problems.
However if I use the handset to GoTo another object, I usually need to do fine tuning adjustments to centre on the new object. But the mount disregards these adjustments, so if I use the GoTo system to centre on a nearby object, or revisit the original object a second time, it’s still off by the same amount.
How do I tell the mount that I have centred on the new object and that it should now be aligned with that object ?
My iOptron MiniTower has a feature that does exactly this – once set up correctly and aligned, for each new object I go to there is an “ALIGN” option, and if I use this it now knows the correct position. Can I do this with SkyWatcher and Synscan ?
I am looking to return my Powerseeker 114eq and get a XT6. I know that my canon rebel T4i will not reach focus. It wont travel enough inwards. I want to know, which is best? Plan A is trying to use Barlow or eyepiece projection. Which will magnify less, eypiece or barlow? Are there any tips for both of tose methods and how to use eyepiece projection? Then, Plan B is moving the mirror. I cant find any good tutorials either. Thanks in advance.
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!
