Astrophotography is really interesting and challenging under light polluted area . I always follow below tips you may also follow my deep sky astrophotography tips to get excellent result under bright light pollution.

If you are following my blog , you may know that I am able to capture NGC5139 under Class 8 Brotle light pollution without any light pollution filter. Check here If you don’t know how to read cloud map and check your light pollution.

Astrophotography tips for beginners – deep sky imaging

  • Tripod – for steady imaging, tripod must be properly balance and steady.
  • Mount – to track deep sky objects to get multiple continuous images
  • Fast Refractor or camera lens with small focal factor e.g f5 – f2 to capture more light and Field of view FoV
  • Main imaging Camera – DSLR or dedicated Astro imaging camera
  • Guiding scope – to guide mount
  • Guiding camera – attach to guiding scope which will give input to mount in order to accurate guiding
  • Integrated Device (optional ) – ASIAIR ,Stellarmate etc.
  • Filters – Narrow band , Light pollutions etc

My simple setup for deep sky astrophotography session.

Tripod

If you have one it’s good but if you don’t have then please get one heavy duty tripod , you may find from below my suggested tripods

  1. Heavy duty Tripod from amazon

Mount

Getting useful and powerful Mount is one of the most important astrophotography tips .We would need mount in order to track object , may times it happens that when we try to capture star images and suddenly get star trails , some times we wanted to do that but even if we want to capture M45 – Orion Nebula and get such star trails , how our photography looks like ?

In order to get steady and continuous image we would need tripod and mount which track the stars and deep sky objects.

There are two types of mount EQ and AZ mount

When i started this hobby i brought simple EQ mount with simple tracking motor attached , it works very good with planet and moon but for deep sky object we would need to give guiding input and it doesn’t have that facility , my suggestion is to get mount which has at least auto guiding port or can work with auto-guiding.

I am using AZ GTi skywatcher mount. Some features i am listing of this mount.

  • This mount is easy to carry
  • Works with my ASIAIR via ASCOM driver.
  • Works with WIFI
  • In budget
  • No need additional Tripod – can fit light weight , heavy duty tripod
  • Auto-guiding via ASCOM
  • Less cables
  • Always Works for me !!!!

You can buy it from Amazon – > AZ GTi

Small focal length Lens or Refractor

Deep sky objects are too far from our planet and some of them are very high magnitude (+ more number ) , even we can’t see them under dark skies . In order to get more light we would need small Focal ration lens or refractor.

My favorite is refractor in range of F4-6 , I am using SVBONY SV 48 refractor with aperture 90 mm and focal length is 500 mm which gives focal ration 5.5 .

Here is the detail review of SVBONY SV48.

You can buy it from Aliexpress or Amazon .

Imaging Camera

Imaging camera is the basic need in astrophotography , you can use below cameras for astrophotography

  1. DSLR unmodified
  2. DSLR modified ( removed UV filter )
  3. Astro dedicated cameras – ZWO ASI camera

I am using ASI224 , you may check review of ASI224.

You can buy ASI camera from Aliexpress site.

Guiding Scope and Guiding Camera

As i said earlier we would need mount in order to track stars or deep sky objects. Even costly mount is not so perfect to do tracking exactly without any error.In order to rectify those errors we would need guiding scope and guiding camera to give input to mount with correction of RA and DA.

ASIAIR

This is the device which give you complete help while doing deep sky astrophotography , please visit here for my full review on ASIAIR.

ASIAIR does Plate solving which is exactly same as alignment of the stars . With AZ Gti and ASIAIR my deep sky astrophotography become so easy , I just need to point my telescope roughtly to north for polar alignment then connect everything , go to any object/star , perform Plate solving , done !!! Start capturing imaging !!! so simple.

You can buy ASIAIR – ZWO ASIAIR AMAZON

Filters

These are mostly used when capturing deep sky objects to get more contrast and reduce light pollution.

Types of filters

  1. LRGB filters – used for monochrome camera – I am using SVBONY LRGB filters
  2. L-Pro – For modified or unmofieid DSLR camera under brightest light polluted area – I have Optolong L-Pro filter
  3. UHC filter – Light pollution filter – I have SVBONY UHC filter
  4. CLS Filter – Light pollution filter for modified DSLR camera . I have SVBONY CLS filter
  5. Narrow band filters – Halpha , OIII and SII . I have Optolong narrow band filters,

If you follow my deep sky astrophotography tips , and get same equipment as i have then you might be get exact same results or better results than me.
