The 72ED is Not bad choice at all. I’m actually considering a second telescope for wide field.
-
It almost everything now. I waited two months for the ZWO OAG and still waiting for the ultra narrowband Filter SII( I ordered it in April)
-
Yes, but needs some skill to balance it. Till now I couldn’t get over 900” subs, but i think the limitation comes from using a guiding scope, but anyway I’m waiting for the OAG to come and see if it get more. I’m Also using a 10” Newtonian, ASI 1600mm, automated Filter wheel , autofocuser, and of course a come corrector. i know a guy using a 12” Newtonian and getting such long shots. But he has the NEQ-6 , almost the same load capacity as the EQ6R. If you go for the 10” , you’ll need to buy additional 5kg counterweight, cause the two comes with the mount are not enough to balance it.

Same problem with me, I give it up anyway as I was getting poor results. I think the PS was out of axis.

EQ6-R High accuracy polar alignment
OJ87 posted a topic in Getting Started Equipment Help and Advice
Hi everyone, I’m still young in astronomy and I just leveled up and build a permanent pier, so I can save the time and the most important thing is also getting a high accurate polar alignment, so I can get longer exposures. Unfortunately I didn’t get the PA to a level over 3-4 mins. It was ok before cause I have a fast telescope and used lrgb with bortel 4 sky. But for narrowband not enough. I usually use sharp cap for polar alignment. I tried the also drift alignment in PHD2 but looked unstable to me as it always changed the direction after every exposure (I have been told to wait a 2 min at least to stake it) but I’m not sure if it’s good enough. could you guys guys help me with some advice and tips getting it better? Thanks alot -
Thank you! i think I wasn’t patient enough to see the video till end. you saved my day! best regards

Hi Everyone, i upgraded my cam from DSLR to ASI 1600mm mono and i could make two imaging session the last two days. but unfortunately i accidentally moved my cam during the transport and i figured it out only today, the result is: my target Galaxy (M81) has diffrent positions in every imaging session, stacking every Channel resulted in diffrent angel for every channel. so any one could give me any trick of how i get them all in the same exact position so i can combine them in photoshop? and how to avoid such mistakes in future? i'm using APT for Imaging. Thank you.
-
Thanks, I will post it there
-
I calibrated it , but Maybe i rotated the camera while trying to reconnect the cam. I will try to calibrate again tonight, thanks a lot, I hope the problem would be so easy solved
-
hmm, you mean Darkframe library? or step calibrating?

Hi everyone, i'm trying to autoguide, but i'm always getting poor guiding graph. i did polar aligment with sharpcap, did it to Excellent, then i start guiding with PHD, which stops after while because it's ineffective. here is a Photo of the lines, i did this immediately after polar Alignement without moving the scope. Any ideas why this happening? balancing seems good to me.

Horizontal lines in Flats

Thank you, i will give it a try. best regards -
Hi Every one, i'm just starting with my mono astrophotographie, today i tried to take Flats using my LCD Flat-Lamp. My cam is ASI 1600mm. i'm tried to get ADU arount 23k , but as i get close to it it showes horzontal lines , Exposure lenth about 0,01293sec. is it normal? Gain was 0 and Offset 50. i tried to find it out in Internet, but not body mention it. i would be happy for any suggetions. Thanks

Thank you Anne for reply: In which Teleskop did you used this filters? I’ll use it now with my 1000mm f4 Telescope, as I said, but in future I may upgrade to SC C11 or go for smaller focal length Teleskop. Could it be a problem using those filters then?

Hi everyone, I'm planning to upgrade to cooled mono (AS I 1600mm Pro) and I want to buy the motorised ZWO filter wheel and LRGBcHa OIII and SII 1,25 filters from Astronomik. Since I'm completely new to mono camera and narrowband filters world, I have a couple of questions and I hope if you could help me: If anyone has the same equipment as I have a fast Teleskop F4 and 1000mm focal length. Would I face any problems with vignetting with my telescope? I know 6nm can show more contrast and details than 12nm, should I take all the filters with the same wave length (6nm)? i have a bortel 4/5 skies. Best regards,
