yes good guiding and nice image and  i like to monitor how the session went ,

PHD is great , and especially the log , this was my last session just on EQR6-R on tripod on patio.

Roger

Really nice rendition , nicely processed,

Roger

OMG! what a setup. Interested to know the specs on the mount ie total weight limits and so..

Lovely M31,

Roger

Great image, especially the colourful starfield, any chance of a few tips for the star colour i always struggle,

I only have Astroart and Photoshop cs2

Roger

One of my favourite nebulas , good one,

Roger

 Nice image, going to try it myself.

Just wondered about the wooden tripod , i have always wondered about flexure and expansion and contraction in hot/cold weather does this happen?

Roger

Thanks all , never heard this talked about till now 😎

Caused by a cosmic ray. See them often when stacking many subs and looking at what sigma clipping rejects.

ok thanks, so they may be in many subs?

On checking my subs last night i noticed what i thought was a scratch in the optical train showing in that sub, so checked the sub before and after to check but its not on those so it only appeared in one sub.
Interested to hear anyones take on this.

Ths sub with the artifact was a Luminance and the others were Red and Green.

Nice Image , lovely zoom.

Roger

This small Sharpless object sits high in the northern fall sky north of SH2-171 which is a common object imaged and south of Abell 85, a supernova remnant. The object responds to mostly red filters so a red luminance can be easily used on this one to produce a nice RRGB. It also does very well with a hydrogen-alpha filter and exposing the camera for a very long time begins to pick up a fainter area around it. It also responds very nice with the sulfur II and oxygen III filters so this one makes for a great narrowband color image.. There is also some fine structure in the object that a larger telescope can capture and produce an amazing image of this object, which is not a common image out there these days.

I saw a colleagues image and thought i might give it a try not expecting much given its faintness, and tried with a 450s sub firstly  and did see ghostly image on live view so doubled to 900s and was sufficiently pleased to setup a Ha plan and managed  22 x 900s (Only 16 would stack in Astroart)with the expectation of getting Oiii and LRGB in future but well pleased with this so far.

Hi, i have that camera as well and wondered what the Temp was as its 17oC here at 3.30 am and the camera has been dead on -20c all night.

Roger

BTW

i am doing 900s subs

Nice one,

Roger

Are you ok with aligning cropping / multiple sessions, as registar is very good.

Roger

Try plugging just the EFW into your laptop and watch what's happening when you change filters in your capturing program.

HTH

Roger

I suppose it wasn't anything to do with Focus ,  sorry to ask but how did you focus with the Baader as opposed to the Astrodon it was a different focus point ?

Stars are naff in the best NB images apparently anyway.

I'm booked on 352 on the Red field from the Wednesday through to the Sunday, but I might stay longer if the weather is good.  I'll have a tent this year rather than the motorhome. 

I'm planning on bringing my ZWO 294MC Pro camera on my trusty 80ED for imaging on my new-to-me AZ EQ6 GT mount.  I probably also bring my Astro-modified Canon 1100D to use on my iOptron Skytracker mount for some wide field targets.

Hi Michael, i would like any tips for my Canon 1000d modified on either of my scopes.

I'd like to come and see your dual rig too. My 2nd attempt is to try a tandem setup. When are you arriving?

23rd Morningish,

your welcome anytime,

Roger

I started with a DSLR (bought a brand new Canon 750d Modded),about 3 years ago with a SW120 and Eq6-r, and got a good grounding. Then last year i got a ZWO ASI ASI183MM Pro with EFW and LRGB filters and used this since with a dual rigged Altair Astro ED66-R and have been amazed with the results and have since gone NB with Ha and Oiii and jumped up to another level although processing is a hugh learning curve, and still got to crack NB star colour.

Roger

Hi all, i am on 314 from 23rd to 30th ,driving a hired caravanette 6 berth for the first time!

Using a dual rig like Carole, Sw120 ed ds-pro , Altair Astro Ed66-r, Canon 1000d and Sky-Watcher EQ6-R PRO and first time at Kelling for my Eagle3 control unit.

Roger

Nice first NB ,i was amazed at the detail in my light polluted sky even with the moon behind me got great results.

I have this camera we should start a help thread for 183 owners to share tips?

I like what i see with the W/O Redcat51,how is it?

Have you seen this

exposure tables 183 chip

Roger

Nice framing, on Gain i have been advised that for these Sony imx183 chips ( i Have ZWO 183mm pro) , a maximum of 178 should be used as Noise tends come to the fore.

How is it with Unity Gain on short exposures as i have good results on those settings.

Checkout this post  Exposure Tables 183 chip

Roger

Nice setup , portable and light.

Roger

I  just wondered why the 200 gain as this affects quite a few areas.
